Changing calling programs field's value in called exit/program

Hi all,

I have a subroutine and it is passed a structure

This subroutine is calling a FM which is an exit .

Can i access and change the value of field in the structure ( which is passed to subroutine ) in the exit.

Currently , that structure is out of scope in the exit.

Please help me .

Thanks and Regards
