Global valiable

[Former Member]

Hello Experts.

I'm beginner of ABAP.

I think valiable declared on the top of program is global valiable

and those declared under subroutain are local valiable.

is it right?

And

If a valiable is declared under event line such as START-OF-SELECTION, AT SELECTION-SCREEN,

which group is this valiable?

Hi Kim,

It is also global. One of the best practise is to create an include. This will separate all the global variables that you declare. Its the common practise. 😃 Hope this will help you.

Rewards if useful.

Hi Kim,

- A variable declared in subroutine is a local variable . it s value will not be accessible outside the subroutine.

-Whereas a variable declared anywhere in the main program is global can be accessed even with the subroutine.

example:

- if a variable say 'z_abc' is declared in main program (global variable) then it can be acessed in the subroutine too.
