SAP Note 27052 - RFDKAG00, RFKKAG00: no list output when run in background

Symptom:

No list is displayed for the RFDKAG00 and RFKKAG00 programs when they
are run in the background.

Cause and prerequisites

At the AT SELECTION-SCRREN point in the program, the system asks for
confirmation of the SY-UCOMM system variable (function entry in OK-CODE). The variable is, however, not set when the program runs in the background.

Solution
Turn the query of the SY-UCOMM system variable into a comment line, or delete it from the coding. Corrected for Release 3.0B. An advance correction is also possible.
