SAP ABAP QUESTIONS & ANSWERS-3


SAP ABAP QUESTIONS & ANSWERS-3 :-


Q. What are interface/conversion programs in SAP ? 
ANS :- 
CONVERSION : LEGACY SYSTEM TO FLAT FILE.
INTERFACE  : FLAT FILE TO SAP SYSTEM.

Q. What are logical databases ? What are the advantages/disadvantages of logical databases ? 
ANS:-
To read data from a database tables we use logical database.
A logical database provides read-only access to a group of related tables to an ABAP/4 program.
Adv:-
The programmer need not worry about the primary key for each table.Because Logical database knows how the different tables relate to each other,and can issue the SELECT command with proper where clause to retrieve the data.
i)An easy-to-use standard user interface.
ii)check functions which check that user input is complete,correct,and plausible.
iii)meaningful data selection.
iv)central authorization checks for database accesses.
v)good read access performance while retaining the hierarchical data view determined by the application logic. 
Disadv:-
i)If you donot specify a logical database in the program attributes,the GET events never occur.
ii)There is no ENDGET command,so the code block associated with an event ends with the next event statement (such as another GET or an END-OF-SELECTION). 

Q. What specific statements do you using when writing a drill down report ? 
ANS:- 
At line-selection,at user-command,at pf.

Q. What do you do when the system crashes in the middle of a BDC batch session ? 

ANS:- 
We will look into the error log file (SM35).

Q. What do you do with errors in BDC batch sessions ? 
ANS:-
We look into the list of incorrect session and process it again. To correct incorrect session we analyize the session to determine which screen and value produced the error.For small errors in data we correct them interactively otherwise
modify batch input program that has generated the session or many times even the datafile.

Q. How do you set up background jobs in SAP ? What are the steps ? What are the event driven batch jobs ? 
ANS:- 
Go to SM36 and create background job by giving job name,job class and job steps(JOB SCHEDULING)

Q. Does SAP handle multiple currencies ? Multiple languages ?

SAP ABAP QUESTIONS & ANSWERS-2



SAP ABAP QUESTIONS & ANSWERS-2 :-


Q. What is a function group ? 
ANS:-

Group of all related functions. 

Q. How are the date and time field values stored in SAP ? 
ANS:-
DD.MM.YYYY.  HH:MM:SS 

Q. Name a few data dictionary objects ?
ANS:-
Tables,views,structures,lock objects,matchcode objects.

Q. What happens when a table is activated in DD ? 
ANS:-
It is available for any insertion,modification and updation of records by any user.

Q. What is a check table and what is a value table ? 
ANS:-
Check table will be at field level checking.
Value table will be at domain level checking ex: scarr table is check table for carrid.

Q. What are match codes ? describe ? 
ANS:-
It is a similar to table index that gives list of possible values for either primary keys or non-primary keys.

Q. What are ranges ? What are number ranges ? 
ANS:-

Max,min values provided in selection screens.

Q. What are select options and what is the diff from parameters ? 
ANS:-
select options provide ranges where as parameters do not. 
SELECT-OPTIONS declares an internal table which is automatically filled with values or ranges of values entered by the end user. For each SELECT-OPTIONS , the system creates a selection table.
SELECT-OPTIONS <SEL> FOR <field>.
A selection table is an internal table with fields SIGN, OPTION, LOW and HIGH. 
The type of LOW and HIGH is the same as that of <field>. 
The SIGN field can take the following values: I Inclusive (should apply) E Exclusive (should not apply) The OPTION field can take the following values: EQ Equal GT Greater than NE Not equal BT Between LE Less  than or equal NB Not between LT Less than CP Contains pattern GE Greater than or equal NP No pattern.
Diff:-
PARAMETERS allow users to enter a single value into an internal field within a report. 
SELECT-OPTIONS allow users to fill an internal table with a range of values. 
For each PARAMETERS or SELECT-OPTIONS statement you should define text elements by choosing 
Goto - Text elements - Selection texts - Change. 
Eg:- Parameters name(30).
when the user executes the ABAP/4 program,an input field for 'name' will appear on the selection screen.You can change the comments on the left side of the input fields by using text elements as described in Selection Texts.

Q. How do you validate the selection criteria of a report ? And how do you display initial values in a selection screen ? 
ANS:-
validate :- by using match code objects.
display :- Parameters <name> default 'xxx'. select-options <name> for spfli-carrid.

Q. What is CTS and what do you know about it ? 
ANS:-
The Change and Transport System (CTS) is a tool that helps you to organize development projects in the ABAP Workbench and in Customizing, and then transport the changes between the SAP Systems and clients in your system landscape.
This documentation provides you with an overview of how to manage changes with the CTS and essential information on setting up your system and client landscape and deciding on a transport strategy. Read and follow this documentation when planning your development project.
For practical information on working with the Change and Transport System, see Change and Transport Organizer and Transport Management System.

Q. Are programs client dependent ? 
ANS:-
Yes. Group of users can access these programs with a client no.

Q. Name a few system global variables you can use in ABAP programs ? 
ANS:-
sy-subrc,sy-dbcnt,sy-lilli,sy-datum,sy-uzeit,sy-ucomm,sy-tabix.....
sy-lilli is absolute no of lines from which the event was triggered.

Q. What are internal tables ? How do you get the number of lines in an internal table ? How to use a specific number occurs statement ? 
ANS:-
i)It is a standard data type object which exists only during the runtime of the program.
They are used to perform table calculations on subsets of database tables and for re-organising the contents of database tables according to users need.
ii)using SY-DBCNT.
iii)The number of memory allocations the system need to allocate for the next record population.

Q. How do you take care of performance issues in your ABAP programs ? 
ANS:-
Performance of ABAPs can be improved by minimizing the amount of data to be transferred. 
The data set must be transferred through the network to the applications, so reducing the amount OF time and also reduces the network traffic.
Some measures that can be taken are: 
- Use views defined in the ABAP/4  DDIC (also has the advantage of better reusability).
- Use field list (SELECT clause) rather than SELECT *.
- Range tables should be avoided (IN operator)
- Avoid nested SELECTS. 

Q. What are datasets ? 
ANS:-
The sequential files(ON APPLICATION SERVER) are called datasets. They are used for file handling in SAP.

Q. How to find the return code of a statement in ABAP programs ? 
ANS:-
Using function modules.



SAP ABAP QUESTIONS & ANSWERS-1


SAP ABAP QUESTIONS & ANSWERS-1 :-


 
Q. What is the typical structure of an ABAP/4 program ? 
ANS:-  Header ,body,footer.

Q. What should be the approach for writing a BDC program ? 
ANS:-
step 1: converting the legacy system data to a flat file to internal table called "conversion".
step 2: transfering the flat file into sap system called "sap data transfer".
step 3: depending upon the bdc type
         i)call transaction(Write the program explicity)
         ii) create sessions (sessions are created and processed.if success data will transfer).

Q. What is a batch input session ? 

ANS:-
Batch input session is an intermediate step between internal table and database table. 
Data along with the action is stored in session ie data for screen fields, to which screen it is passed,program name behind it, and how next screen is processed.

Q. What is the alternative to batch input session ? 

ANS:-
Call transaction.

Q. A situation: An ABAP program creates a batch input session. We need to submit the program and the batch session in back ground. How to do it ? 
ANS:-
Go to SM36 and create background job by giving job name,job class and job steps (JOB SCHEDULING) 

Q. What are the problems in processing batch input sessions ?  How is batch input process different from processing online ? 
ANS:-
PROBLEMS:-
i) If the user forgets to opt for keep session then the session will be automatically removed from the session queue(log remains).  However if session is processed we may delete it manually.
ii)if session processing fails data will not be transferred to SAP database table.

Q. What are the different types of data dictionary objects ?
 
ANS:-
Tables, structures, views, domains, data elements, lock objects, Matchcode objects.

Q. How many types of tables exists and what are they in data dictionary ? 

ANS:-
4 types of tables
i)Transparent tables - Exists with the same structure both in dictionary as well as in database exactly with the same data and fields.   Both Opensql and Nativesql can be used.
ii)Pool tables
iii)Cluster tables - These are logical tables that are arranged as records of transparent tables.one cannot use native sql on these tables(only opensql).They are not managable directly using database system tools.
iv)Internal tables.

Q. What is the step by step process to create a table in data dictionary ? 
ANS:-
step 1: creating domains(data type,field length,range).
step 2: creating data elements(properties and type for a table field).
step 3: creating tables(SE11).

Q. Can a transparent table exist in data dictionary but not in the data base physically ?
ANS:- NO.
Transparent table do exist with the same structure both in the dictionary as well as in the database,exactly with the same data and fields.

Q. What are the domains and data elements ? 
ANS:-
DOMAINS : Formal definition of the data types.they set attributes such  as data type,length,range.
Data element : a field in r/3 system is a data element.

Q. Can you create a table with fields not referring to data elements ? 
ANS:- 
YES.
eg:- ITAB LIKE SPFLI.here we are referening to a data object(SPFLI) not data element.

Q. What is the advantage of structures? How do you use them in the ABAP programs ? 
ANS:-
Adv:- GLOBAL EXISTANCE(these could be used by any other program without creating it again). 

Q. What does an extract statement do in the ABAP program ? 
ANS:-
Once you have declared the possible record types as field groups and defined their structure, you can fill the extract dataset using the following statements:
EXTRACT <fg>.
When the first EXTRACT statement occurs in a program, the system creates the extract dataset and adds the first extract record to it. In each subsequent EXTRACT statement, the new extract record is added to the dataset
EXTRACT HEADER.
When you extract the data, the record is filled with the current values of the corresponding fields.
As soon as the system has processed the first EXTRACT statement for a field group <fg>, the structure of the corresponding extract record in the extract dataset is fixed. You can no longer insert new fields into the field groups <fg> and HEADER. If you try to modify one of the field groups afterwards and use it in another EXTRACT statement, a runtime error occurs. 
By processing EXTRACT statements several times using different field groups, you fill the extract dataset with records of different length and structure. Since you can modify field groups dynamically up to their first usage in an EXTRACT statement, extract datasets provide the advantage that you need not determine the structure at the beginning of the program.

Q. What is a collect statement? How is it different from append ? 
ANS:-
If an entry with the same key already exists, the COLLECT statement does not append a new line, but adds the contents of the numeric fields in the work area to the contents of the numeric fields in the existing entry. 

Q. What are the events in ABAP/4 language ? 
ANS:-
Initialization, At selection-screen,Start-of-selection,end-of-selection,top-of-page,end-of-page, At line-selection,At user-command,At PF,Get,At New,At last,at end, at first. 

Q. What is an interactive report ? What is the obvious diff of such report compared with classical type reports ? 
ANS:- 
An Interactive report is a dynamic drill down report that produces the list on users choice.
diff:-
a) The list produced by classical report doesn't allow user to interact with the system.
   The list produced by interactive report allows the user to interact with the system.
b) Once a classical report executed user looses control.ir user has control.
c) In classical report drilling is not possible.in interactive drilling is possible.

Q. What is a drill down report ? 
ANS:-
Its an Interactive report where in the user can get more relavent data by selecting explicitly.

Q. How do you write a function module in SAP ? describe. 
ANS:-
Creating function module:-
called program - se37-creating funcgrp,funcmodule by assigning attributes,importing,exporting,tables,exceptions.
calling program - SE38-in pgm click pattern and write function name- provide export,import,tables,exception values.

Q. What are the exceptions in function module ? 
ANS:-

COMMUNICATION_FAILURE 
SYSTEM_FAILURE

General Interview Questions


General Interview Questions :-



Q) Tell me about yourself.
A) Make a short, organized statement of your education and professional achievements and professional goals. Then, briefly describe your qualifications for the job and the contributions you could make to the organization.


Q) Why do you want to work here ? or What about our company interests you ?
A) Few questions are more important than these, so it is important to answer them clearly and with enthusiasm. Show the interviewer your interest in the company. Share what you learned about the job, the company and the industry through your own research. Talk about how your professional skills will benefit the company. Unless you work in sales, your answer should never be simply: "money." The interviewer will wonder if you really care about the job.


Q) Why did you leave your last job ?
A) The interviewer may want to know if you had any problems on your last job. If you did not have any problems, simply give a reason, such as: relocated away from job; company went out of business; laid off; temporary job; no possibility of advancement; wanted a job better suited to your skills.

If you did have problems, be honest. Show that you can accept responsibility and learn from your mistakes. You should explain any problems you had (or still have) with an employer, but don't describe that employer in negative terms. Demonstrate that it was a learning experience that will not affect your future work.


Q) What are your best skills ?
A) If you have sufficiently researched the organization, you should be able to imagine what skills the company values. List them, then give examples where you have demonstrated these skills.


Q) What is your major weakness ?
A) Be positive; turn a weakness into strength. For example, you might say: "I often worry too much over my work. Sometimes I work late to make sure the job is done well."


Q) Do you prefer to work by yourself or with others ?
A) The ideal answer is one of flexibility. However, be honest. Give examples describing how you have worked in both situations.


Q) What are your career goals ? or What are your future plans ?
A) The interviewer wants to know if your plans and the company's goals are compatible. Let him know that you are ambitious enough to plan ahead. Talk about your desire to learn more and improve your performance, and be specific as possible about how you will meet the goals you have set for yourself.


Q) What are your hobbies ? and Do you play any sports ?
A) The interviewer may be looking for evidence of your job skills outside of your professional experience. For example, hobbies such as chess or bridge demonstrate analytical skills. Reading, music, and painting are creative hobbies. Individual sports show determination and stamina, while group sport activities may indicate you are comfortable working as part of a team.

Also, the interviewer might simply be curious as to whether you have a life outside of work. Employees who have creative or athletic outlets for their stress are often healthier, happier and more productive.


Q) What salary are you expecting ?
A) You probably don't want to answer this one directly. Instead, deflect the question back to the interviewer by saying something like: "I don't know. What are you planning on paying the best candidate?" Let the employer make the first offer.

However, it is still important to know what the current salary range is for the profession. Find salary surveys at the library or on the Internet, and check the classifieds to see what comparable jobs in your area are paying. This information can help you negotiate compensation once the employer makes an offer.


Q) What have I forgotten to ask ?
A) Use this as a chance to summarize your good characteristics and attributes and how they may be used to benefit the organization. Convince the interviewer that you understand the job requirements and that you can succeed.





SAP BI QUESTIONS & ANSWERS-10


SAP BI QUESTIONS & ANSWERS-10 :-


1) Transaction Code for the following ?
A) 1) To delete setup tables -> LBWG
2) To fill setup tables -> OLI*BW
3) Currency exchange rates -> OB08
4) BW Delta Queue Monitor -> RSA7
5) DB connect -> RSDBC

2) What is Real Time Data Acquisition ?
A) Real-time data acquisition supports tactical decision-making. It also supports operational reporting by allowing you to send data to the delta queue or PSA table in real-time. You then use a daemon to transfer Data Store objects to the operational Data Store layer at frequent regular intervals. The data is stored persistently in BI.

3) Difference between display attributes and navigational attributes ? 
A) Display attribute is one which is used only for display purpose in the report.Where as navigational attribute is used for drilling down in the report.We don't need to maintain Nav attribute in the cube as a characteristic(that is the advantage) to drill down.

4) What are the different variables used in BEX ?
A) Variable with default entry
Replacement path
SAP exit
Customer exit
Authorization

5) What are Return Tables ?
A) When we want to return multiple records, instead of single value, we use the return table in the Update Routine. Example: If we have total telephone expense for a Cost Center, using a return table we can get expense per employee

6) What are Start routines, Transfer routines and Update routines ?
A) Start Routines: The start routine is run for each DataPackage after the data has been written to the PSA and before the transfer rules have been executed. It allows complex computations for a key figure or a characteristic. It has no return value. Its purpose is to execute preliminary calculations and to store them in global DataStructures. This structure or table can be accessed in the other routines. The entire DataPackage in the transfer structure format is used as a parameter for the routine.
• Transfer / Update Routines: They are defined at the InfoObject level. It is like the Start Routine. It is independent of the DataSource. We can use this to define Global Data and Global Checks.

7) What is the difference between ODS and InfoCube and MultiProvider ?
A) ODS: Provides granular data, allows overwrite and data is in transparent tables, ideal for drilldown and RRI.
• CUBE: Follows the star schema, we can only append data, ideal for primary reporting.
• MultiProvider: Does not have physical data. It allows to access data from different InfoProviders (Cube, ODS, InfoObject). It is also preferred for reporting.

8) What are the steps involved in LO Extraction ?
A) The steps are:
• RSA5 Select the DataSources
• LBWE Maintain DataSources and Activate Extract Structures
• LBWG Delete Setup Tables
• 0LI*BW Setup tables
• RSA3 Check extraction and the data in Setup tables
• LBWQ Check the extraction queue
• LBWF Log for LO Extract Structures
• RSA7 BW Delta Queue Monitor.

9) Can an InfoObject be an InfoProvider, how and why ?
A) Yes, when we want to report on Characteristics or Master Data. We have to right click on the InfoArea and select "Insert characteristic as data target". For example, we can make 0CUSTOMER as an InfoProvider and report on it.

10) What are Process Types & Process variant ?
A) Process types are General services, Load Process & subsequent processing, Data Target Administration, Reporting agent & Other BW services.
Process variant (start variant) is the place the process type knows when & where to start.

11) Four types of Sid tables ?
A) X time independent navigational attributes sid tables
Y time dependent navigational attributes sid tables
H hierarchy sid tables
I hierarchy structure sid tables.

X-table = A table to link material SIDs with SIDs for time-independent navigation attributes.
Y-table = A table to link material SIDs with SIDS for time-dependent navigation attributes.

12) How can you improve the performance of a query ?
A) Query Performance can be improved by making the Aggregates having all the Chars & KF used in Query.





SAP BI QUESTIONS & ANSWERS-9


SAP BI QUESTIONS & ANSWERS-9 :-



1) what is the t-code to create INDEX in SAP BI(7.0) ? /How can we create the index in SAP BW/BI ?
A) I am sorry as I am not aware of TCode for Index. But, I can roughly tell how to create Index. Creating Indexing is apart of Performance Issues on Query. As we know thatwhenever we load data to the data target, Primary indexesare created automatically and uses Linear search i.e, searchrecord by record, whereas when we can create SecondaryIndexes, it will follow Binary search and hence the queryperformance improves.
To create a Secondary Index,
1. Select your data target(Infocube or DSO)and select contextmenu and select Manage.
2. Select the Performance tab and select 'Create Index' button.
3. In the new dialog box, Select 'Selection' and then select'Immediate' and click Save.
4. Select 'Start' and click 'Continue'.
Once the Secondary Index is created, a check mark is createdin front of the data target.
B) Index can be created by managing a cube. There are two types of indexes. They are primary index and secondary index.Primary index is automatically created by the system ie system generated index. Secondary index is created by us.
Indexing is a process of storing data according to an index like in a phone book. Secondary indexes are of bit map andbinary tree.

2) how can we enhance the data sources, explain me with example ?
A)

1.find the structure of the data source and goto se11 using append structure add the require fileds to the structure and activate
2.goto rsa6 select ur datasource and click on change icon and unhide the fileds and generate the datasoure.
3. goto tcode cmod create a project and assign RSRA0001
write the require code in the standard Include.
enhancement name is RSAP0001
find the structure of the datasource i.e in rsa5 and goto se11 using append structure add the require fileds to the structure and activategoto rsa6 select ur datasource and click on change icon and unhide the fileds(important)and generate the datasoure.
goto tcode cmod create a project and assign RSAP0001write the require code in the standard Include.

3) Explain about monitering tcodes RSMO RSPC RSPCM and how to work with the DATA LOAD issues ?
A)

RSMO: monitoring the data loads.
RSPC: for creating process chains
RSPCM: monitor daily process chains.
RSPC: using RSPC we can create a process chain to schedule any data load.
RSPCM: After creating the process chain at RSPC level, if u wants to monitor the data load(data failures)we should add that process chain to RSPCM which is used to monitor all the data loads.
RSMO: used to monitor data loads which are scheduled by only process chains.

4) what are the errors in process chain, how can we solve them ?
A) IN log overview we can check what all errors are there and Accordingly handle the errorsThis key figure (0TCTNPRSTER) specifies the number of Processes or process chains that finished with errors. The key figure has the data type DEC (number).

5) What is difference between BI and BO'S with BI ?
A) In BI we are using BEx suite for different reporting requirements but in BO's we have so many components which solves various reporting requirements in terms of more visualization.

Crystal report designer in BO similar to Report designer in BI
Xcelsius similar to WAD,
Bex analyzer similar to Voyager

By using Universe designer we create a universe (similar to Multiprovider) in BO and we can use this universe to create reports. A BI connection is needed to create universe in BO (nothing but source system connection in BI.

6) I want to start a new project with NW BI 7.0. Which frontends do I use ?
A)
• It is generally recommended to evaluate and use the Busines Object premium packages.
• For selected areas, such as web- & Excel based OLAP analysis, it will still be beneficial to leverage BEx Analyzer & BEx Web Analyzer for new projects as they provide superior OLAP features compared to Busines Object Voyager.
• Projects requiring an Excel OLAP Integration should be carried out with BEx Analyzer until Pioneer arrives.
• If you are already experienced with the BEx Web Applications Designer, and want to build heavy weight BI Web applications, you can still do this using BEx Web Application Designer, but please evaluate Visual Composer in NW Composition Environment 7.1.1, as VC/CE tools will be the go-to solutions for design of web-based, composite applications in the future.

7) What is variable exit ? Give me its structure ?
A) SAP provides a variable of type customer exit for BW queries which customer is able to manage its values depends on their business requirements. It is necessary some background in ABAP to start in this area, the proposal of this document is to help on those tasks. It is structured in the following sequence:
Project management of SAP Enhancements
Query BEX Query Designer and Variable Type Customer Exit
Customer Exit and ABAP Code
Test and Debug
Additional Information

8) After starting an InfoPackage, I can't see any job running in SM37. How can this possibly be ?
A) In the source system, the extraction job has the name BI*<request id>. If the DataSource is in SAP ERP, you can check for this job in your ERP system and see what's the status of the extraction. If you're moving data from BW to BW itself (e.g. you're loading data from a DSO to a datamart InfoCube), the extraction job will be running in BW itself.
Once the extraction job has been completed, in the BW system the data update is done through a dialog process, which you can only monitor in SM50. You won't see any jobs in SM37 related to the update.

In the Scheduling tab of an InfoPackage, you can choose between two options:
• Start Data Load Immediately - The request will be created in foreground using dialog process;
• Start Later in Batch - The request will be created using a backgroud job.
However, this only refers to the request creation. Even if you choose the 2nd option, the completion of this job doesn't mean that the load has been completed as well. It just means that the request has been created successfully.
Only when you check the option Request Batch Process Runs Until All Data Has Been Updated in BW this job will be running in SM37 till the upload is complete. Otherwise the only way to monitor your load is SM37 for the extractor job and SM50 for the ETL processing and the update into a data target.
Notice also that the Start Later in Batch setting is hidden if the InfoPackage is used in a process chain. This is because the start of the request is determined by the process chain itself. Therefore, the request is created by the job associated to the process chain's process

9) What is the use of BI accelerator monitor ?
A) The BI accelerator monitor is used for the technical administration and maintenance of the BI accelerator. It provides an overview of the current status of the BI accelerator.
The BI accelerator monitor displays the results of the consistency checks. These checks run periodically on the BI accelerator. If problems occur, the system automatically proposes appropriate actions. These actions involve BI accelerator repair functions which can be used to fix problems.
The detailed BI accelerator monitors offers a detailed, technical overview of the hardware, BI accelerator services, any trace files that exist and the BI accelerator indexes.

10) Why do you go for function module in generic extraction ?
A) If you have to get data from more than 1 table and also incorporate some logic then you would use a fn module extractor. It is like a program where you would code using ABAP and have all your logic incorporated.

SAP BI QUESTIONS & ANSWERS-8


SAP BI QUESTIONS & ANSWERS-8 :-


Q) Different types in LO's ?
A) Direct Delta, Queued Delta, Serialized V3 update, Unserialized V3 Update.
Direct Delta: - With every document posted in R/3, the extraction data is transferred directly into the BW delta queue. Each document posting with delta extraction becomes exactly one LUW in the corresponding Delta queue.
Queued Delta: - The extraction data from the application is collected in extraction queue instead of as update data and can be transferred to the BW delta queue by an update collection run, as in the V3 update.

Q) What does LO Cockpit contain ?
A)
* Maintaining Extract structure.
* Maintaining DataSources.
* Activating Updates.
* Controlling Updates.

Q) What are Process Chains ?
A) TCode is RSPC, is a sequence of processes scheduled in the background & waiting to be triggered by a specific event. Process chains nothing but grouping processes. Process variant (start variant) is the place the process chain knows where to start.
There should be min and max one start variant in each process chain, here we specify when should the process chain start by giving date and time or if you want to start immediately
Some of theses processes trigger an event of their own that in-turn triggers other processes.
Ex: - Start chain &#8594; Delete BCube indexes &#8594; Load data from the source system to PSA &#8594;
Load data from PSA to DataTarget ODS &#8594; Load data from ODS
to BCube &#8594; Create Indexes for BCube after loading data &#8594; Create database statistics &#8594; Roll-Up data into the aggregate &#8594; Restart chain from beginning.

Q) What are Process Types & Process variant ?
A) Process types are General services, Load Process & subsequent processing, Data Target Administration, Reporting agent & Other BW services.
Process variant (start variant) is the place the process type knows when & where to start.

Q) Difference between MasterData & Transaction InfoPackage ?
A) 5 tabs in Masterdata & 6 tabs in Transaction data, the extra tab in Transaction data is DATA TARGETS.

Q) Types of Updates ?
A) Full Update, Init Delta Update & Delta Update.

Q) For Full update possible while loading data from R/3 ?
A) InfoPackage &#8594; Scheduler &#8594; Repair Request flag (check).
This is only possible when we use MM & SD modules.

Q) Why it takes more time while loading the transaction data even to load the transaction without master data (we check the checkbox, Always Update data, even if no master data exits for the data) ?
A) Because while loading the data it has to create SID keys for transaction data.

Q) For what we use HIDE fields, SELECT fields & CANCELLATION fields ?
A) Selection fields-- The only purpose is when we check this column, the field will appear in InfoPackage Data selection tab.
Hide fields -- These fields are not transferred to BW transfer structure.
Cancellation - It will reverse the posted documents of keyfigures of customer defined by multiplying it with -1...and nullifying the value.
I think this is reverse posting

Q) Transporting.
A) When it comes to transporting for R/3 and BW, u should always transport all the R/3 Objects first………once you transport all the R/3 objects to the 2nd system, you have to replicate the datasources into the 2nd BW system…and then transport BW objects.
First you will transport all the datasources from 1st R/3 system to 2nd R/3 System. Second, you will replicate the datasources from 2nd R/3 system into 2nd BW system. Third, you will transport all the BW Objects from 1st BW system to 2nd BW system.
You have to send your extractors first to the corresponding R/3 Q Box and replicate that to BW. Then you have to do this transport in BW. Development, testing and then production

Q) When does a transfer structure contain more fields than the communication structure of an InfoSource ?
A) If we use a routine to enhance a field in the communication from several fields in the transfer structure, the communication structure may contain more fields.

Q) What is the PSA, technical name of PSA, Uses ?
A) When we want to delete the data in InfoProvider & again want to re-load the data, at this stage we can directly load from PSA not going to extract from R/3.

Q) Variables in Reporting ?
A) Characteristics values, Text, Hierarchies, Hierarchy nodes & Formula elements,

Q) Variable processing types in Reporting ?
A) Manual, Replacement path, SAP Exit, Authorizations, Customer Exit

Q) Why we use this RSRP0001 Enhancement ?
A) For enhancing the Customer Exit in reporting.

Q) What is the use of Filters ?
A) It Restricts Data.

Q) What is the use of Conditioning ?
A) To retrieve data based on particular conditions like less than, greater than, less than or equal etc.,

Q) What is NODIM ?
A) For example it converts 5lts + 5kgs = 10.

Q) What for Exception's ? How can I get PINK color ?
A) To differentiate values with colors, by adding relevant colors u can get pink.

Q) Why SAPLRSAP is used ?
A) We use these function modules for enhancing in r/3.

Q) Where are workbooks saved ?
A) Workbooks are saved in favorites.

Q) Can Favorites accessed by other users ?
A) No, they need authorization.

Q) What is InfoSet ?
A) An InfoSet is a special view of a dataset, such as logical database, table join, table, and sequential file, and is used by SAP Query as a source data. InfoSets determine the tables or fields in these tables that can be referenced by a report. In most cases, InfoSets are based on logical databases.
SAP Query includes a component for maintaining InfoSets. When you create an InfoSet, a DataSource in an application system is selected.
Navigating in a BW to an InfoSet Query, using one or more ODS objects or InfoObjects.
You can also drill-through to BEx queries and InfoSet Queries from a second BW system, that isConnected as a data mart.
The InfoSet Query functions allow you to report using flat data tables (master data reporting).
Choose InfoObjects or ODS objects as data sources. These can be connected using joins.
You define the data sources in an InfoSet. An InfoSet can contain data from one or more tables that are connected to one another by key fields.
The data sources specified in the InfoSet form the basis of the InfoSet Query.

Q) LO's ?
A)
Synchronous update (V1 update)
Statistics update is carried out at the same time as the document update in the same task.
• Asynchronous update (V2 update)
Document update and the statistics update take place separately in different tasks.
• Collective update (V3 update)
Again, document update is separate from the statistics update. However, in contrast to the V2 update, the V3 collective statistics update must be scheduled as a job.
Successfully scheduling the update will ensure that all the necessary information
Structures are properly updated when new or existing documents are processed.
Scheduling intervals should be based on the amount of activity on a particular OLTPsystem. For example, a development system with a relatively low or no volume of new documents may only need to run the V3 update on a weekly basis. A full production environment, with hundreds of transactions per hour may have to be updated every 15 to 30 minutes.
SAP standard background job scheduling functionality may be used in order to schedule the V3 updates successfully. It is possible to verify that all V3 updates are successfully completed via transaction SM13. This transaction will take you to the “UPDATE RECORDS: MAIN MENU” screen. At this screen, enter asterisk as your user (for all users), flag the radio button 'All' and hit enter. Any outstanding V3 updates will be listed. While a non-executed V3 update will not hinder your OLTP system, by administering the V3 update jobs properly, your information structures will be current and overall performance will be improved.
