we have a new new Z field called "Vendor material class" created in "MRP 2 view" as per the customer requirement . we maintained the values all the values via a Z transation code. but when you want to save a value for this filed in MM02 it is not getting saved and a message " No changes made" in our Production system.
but where are in our test box we were able to save the values. the program versions are same in both the systems. let me know if i am missing any congigurations for this field which saves the value in Production system.
appreciate your help on this.
