Passing sy-repid Not Allowed
In ABAP Objects, the following statement causes an error message:
CALL FUNCTION func EXPORTING p = sy-repid.
Correct syntax:
DATA repname TYPE sy-repid.
repname = sy-repid.
CALL FUNCTION func EXPORTING p = repname.
Reason:
When the parameters are passed to the formal parameters, sy-repid already contains the name of the
main program of the procedure you have called, even though you intended to pass the name of the calling program.
