1. What is the typical structure of an ABAP program? Secretary




2. What are field symbols and field groups.? 
Ans: Field symbols: Field symbols are like pointers. Placeholders for fields or arbitrary data objects.
Field group: A field group combines several fields under one name. 
****	Have you used "component idx of structure" clause with field groups? 





3. What should be the approach for writing a BDC program? 
Ans. 
•	Analyzing data from local file.
•	Analyzing transaction
•	Declaring internal table
Similar to local file.
Similar to BDCDATA.
•	Transferring data from local file to internal table.
•	Population of BDCDATA. using call transaction/session method)

4. What is a batch input session? 
Ans. In this method transfer data from internal table to database table through sessions. Session is intermediate step between internal table & database table. Unless session is processed, the data is not transferred to the database table.

5. What is the alternative to batch input session? 
Ans. Call transaction method.

6. A situation: An ABAP program creates a batch-input session. We need to submit the program and the batch session in background. How to do it? 
Ans. You should process batch-input sessions in the foreground or using the error display if you want to test the data transfer. If you want to execute the data transfer or test its performance, you should process the sessions in the background. To process the sessions in the background, Set the Run mode to Background.

7. What z the diff b/n a pool table and a transparent table and how they are stored at the database level.
Ans. From user point of view all tables are used to store data. From administrator point of view Transparent tables do exists with the same structure both in the dictionary as well as in the database.
Pool & Clustered tables are Logical tables, which are arranged as records of transparent table. These are not manageable directly by using database system tools.

8. What are the problems in processing batch input sessions? 
Ans.




Q.   How is batch input process different from processing online? 
Ans. For online (Session method) external data is deposited in a session for later processing. 
For inline (call transaction method) the entire batch input process takes place inline in your program. 

9. What do you define in the domain and data element. 
Ans. Domain is formal definition of data types from a technical point of view. Sets attributes i.e., type, range, length . . . 
DataElements are definition of the properties and type for a table field. It is an intermediate between the object type domain & table filed.

10. What are the different types of data dictionary objects? 
Ans.
•	Table.
•	Structures.
•	Views. 
•	Dataelement.
•	Domains.
•	Lock Objects.
•	Match code objects.
