Item category based on Plant
I have a scenario where the same material can have different item categoies like TAN, TAS or MTO etc based on plant.
for example material A can have item category as TAN in plant1, and MTO in plant2.
requirement is to automate the item category determination logic based on the plant, is there a way to acheive this?
as for as I know, we may have to do the custom development in the user exit MOVE_FIELDS_TO_VBAP.
but my question is
1. How do I link the plant to the item category?
2. is there a way to acheive this with SAP standard techniques(may be some thing like CMIR or usage etc)?
Thanks in advance for your help.
