Hi!
Facing the same problem with field ZLSPR in tcode fbz0 (Payment proposal).
I did everything as described above, more than that i also assigned my authorization object to FBZ0 in SU24 and checked auth/object_disabling_active = Y. But anyway any user can change the value in this field. Trace shows nothing.
What could i miss?
Thanks in advance!
Regards, Ilshat.
