We have the following scenario:
For certain material types we recieve the materials via ALE from an external system. As the external system controls the short description we need to block the short description from being changed in SAP ECC directly.
What is the best way to accomplish this?
Currently we have a custom field reference group assigned to a set of material types and defined via field control customizings that for this field reference, field group 020 would be read-only.(020 included the short descriptions out of MAKT)
This works fine in online mode, however it seems that this is also blocking updates coming in via IDoc. Now strangly we also have long texts out of STXL blocked via customizing, but here the problem doesn't occur. We can still set those via iDoc updates.
Did anyone experienced similar problems and how were they solved?
Thanks in advance,
