I am facing this issue in maintaining a UoM. I have marked the specific UoM (PC) as Non-Commercial unit (by removing the Commercial Unit tick box) and hence as per standard sap it should not appear in F4 search help in Material Master. However, it is appearing in F4 search help when I try to check this in Alternative Unit of Measure (Additional Data). And I can also use the UoM for commercial transactions like posting consumption.
Can you please let me know the reason for this anamoly? Your comments are greatly appreciated.
