set not visible in GGB0
I've created a set ZZZZ based on table USER_ADDR and field BNAME to have a set of user names.
in GGB0, I'm making a validation on FI document header level. so in the 'check' section I select
"SYST-UNAME" "IN" and go to setdiretory to look for my set, but I get the message GB551 "Set ZZZZ does not exist or cannot be used. "
Anybody any idea?
