General
Q. What are ABAP Program Types?
- Executable Program[Type 1]- This is REPORT program which can be executed by the program name or using a transaction code or can be called using SUBMIT and can have its own screens.
- Module Pool [Type M] - Usually a PROGRAM statement can be started using a transaction code, can be called using CALL TRANSACTION or LEAVE TO TRANSACTION & have their own screens.
- Function Group[]Type F- This is a FUNCTION-POOL statement, non-executable which acts as a container for function modules & can have its own screens.
- Class Definition[Type K ]- This is a CLASS-POOL statement, non-executable and container for classes.
- Interface Definition [Type J]- This is a CLASS-POOL statement, non-executable & container for interfaces.
- Subroutine Pool [Type S ]-This is a PROGRAM statement, non-executable & container for subroutines .
- Type Groups [Type T ]- This is a TYPE-POOL statement which is non-executable and acts as a container for type definitions.
- Include Program [Type I ]-Non-executable and container for source code modules.
