No Transfer of sy-subrc

The system field sy-subrc must not be used in ABAP Objects - and, since Release 7.0, also outside of classes - as an actual parameter for the output parameters of external procedures
.

In ABAP Objects, the following statement causes an error message:

CALL FUNCTION func IMPORTING p = sy-subrc.

Correct syntax:

DATA subrc TYPE sy-subrc.

CALL FUNCTION func IMPORTING p = subrc.

Reason:

After parameter transfer, sy-subrc is set by the call statement. This overwrites the transferred value. With a few exceptions, system fields should never be overwritten explicitly in a program.
