We have requirement for Creation/extension/changing of MMR (MM01/MM02/MM12).
Creation of MMR for certain material types carried out by MDM team from SRM side.In this case these materials replicated from SRM-MDM to R/3 4.7.
In such case core users from R/3 side can able to change MM fields relevent to MDM managed to fields.So that we want to restrict these fields (Replicated from MDM).to further change
The changes to MMR is only from the MDM side.Not from R/3 side
we dicided to make these fields grey out(Not Editble).through ABAP Development
If we go through standard configuration of field stutus as a grey out from Field selection/Field Reference.based on materials types/Transaction.then we will face problem while replicating master data from MDM to R/3 .this means that
If we r creating/changing materials from MDM side.and replicated to R/3 side.
Because in R/3 side if i make these fields as grey out .It won't take input values while replicating data from MDM to R/3.so i could end up with idoc error.
Finally the above process is excluded
If want to go through ABAP development,plz guide on this
If any one face this kind of requirement.Plz guide me
