Question:
Stumped trying to add additional field to VA05.
Running R/3 enterprise (v4.7 to release SAPKH47010).
Have followed SAP OSS note to add a field to VA05 display, by mod to structure VBMTVZ & User-exit V05tZZMO (even though this OSS note is only released for 4.6).
Field (KVGR3) is filled in user-exit (seen by debug), but does not appear in the ALV selection popup.
Welcome any suggestions for adding fields to VA05 (both list display and selection criteria).
Thanks,
A
