Differences between Macros & Subroutines in SAP

Differences between Macros & Subroutines:-

 Macros Subroutines

1. In macro definition should be the 

first & the calling should be the next. 

2. The definition of the macro as 

well as the calling of the macro in 

the same program.

3. Macros can take up to 9 place 

holders. 

4. We can place any executable 

statements after the definition of the 

macro.

5. Macros are used in HR ABAP.

1. In subroutine calling should be the 

first & definition should be the next.

2. The definition of the subroutine as 

well as the calling of the subroutine 

may or may not be in the same 

program.

3. Subroutines can take any number 

of place holders.

4. We can‘t place any executable 

statements after the definition of the 

macro.

5. Subroutines are used in both 

ABAP & HR ABAP.

Global data:-

 Subroutines can access the global declarations in which they are 

defined.

When ever the changes occurred in the subroutine those changes will be reflected 

to global declarations. 

Note:-

LOCAL is the keyword to avoid the changes in subroutines.Differences between Macros & Subroutines:-
