Cascading exceptions through calling chain

[Former Member]

Debbuging SAP code over the years, I often witnessed a situation where exceptions were cascading automatically between successive nested function calls. I try to reproduce the same without success

If I do not declare the exception at the call, I end up with a short dump(classic), if I do declare it, then I get the requested subrc but it does not casade back to the calling function.

How the hell SAP manages this

I don't exactly understand the situation, but if in the calling program, you put something like:

CALL FUNCTION abc

EXPORTING

IMPORTING

TABLES

EXCEPTIONS

error_message = 1.

Any A,E errors in the called FM will be handled/cascaded to the calling program.

For more information, check out the online documentation (t-code ABAPDOCU) for 'CALL FUNCTION'

Thanks & regards,
