Does every ABAP/4 have a modular structure

Yes.

What is Modularization and its benefits

If the program contains the same or similar blocks of statements or it is required to process the s...

Name the ABAP/4 Modularization techniques

• Source code module.
• Subroutines.
• Functions.

How can we create callable modules of program code within one ABAP/4 program

• By defining Macros.
• By creating include programs in the library.
M is the attrib...

Is it possible to pass data to and from include programs explicitly

No. If it is required to pass data to and from modules it is required to use subroutines or functio...

What are subroutines

Subroutines are program modules, which can be called from other ABAP/4 programs or within the same ...

What are the types of Subroutines?

• Internal Subroutines: The source code of the internal subroutines will be in the same ABAP/4 ...

It is not possible to create an ABAP/4 program, which contains only Subroutines

False.

A subroutine can contain nested form and endform blocks. (T/F)

False.

What are the different types of parameters

Formal Parameters: Parameters, which are defined during the definition of subroutine with the FORM ...

How can one distinguish between different kinds of parameters

• Input parameters are used to pass data to subroutines.
• Output parameters are used to ...

What are the different methods of passing data

• Calling by reference: During a subroutine call, only the address of the actual parameter is ...

How can an internal table with Header line and one without header line be distinguished

Itab[] is used in the form and endform if the internal table is passed with a header line.

What should be declared explicitly in the corresponding ABAP/4 Statements to access internal tables

Work Area. This is required as the Work Area is the interface for transferring data to and from the...

A subroutine can be terminated unconditionally using EXIT

True.

Function Modules are also external Subroutines

True.

What is the difference between the function module and a normal ABAP/4 subroutine

In contrast to normal subroutines function modules have uniquely defined interface. Declaring data ...

What is a function group

A function group is a collection of logically related modules that share global data with each othe...

What is the disadvantage of a call by reference

During a call by reference damage or loss of data is not restricted to the subroutine, but will ins...

A function module can be called from a transaction screen outside an ABAP/4 program

True.
