I want to make the Material Group 1- MVKE-MVGR1 (Field Selection Group 54) field in the Material Master as a mandatory field. The problem is, when I make it mandatory (be it via the Material Type or the Transaction code e.g. MM01) in Tcode OMS9, not only is Material Group 1 made mandatory, Material Group 2, 3, 4 and 5 is also made mandatory. I just want to make the Material Group 1 field as mandatory but the other fields such Material Group 2,3,4 and 5 optional (not mandatory).
How can I do this ? If anybody can give me some step by step instruction, I will really appreciate it.
