Fisrt, sorry but my english is not good.
I need to use a SD BOM on SO to applicate a item category usage to BOM Item.
My SD BOM is create in CS01.
A10 The header is a Material (item category group Zxxx for BOM)
There are two items on the SD BOM
A50 Material (item category group ERLA)
A70 Material (item category group LEIH)
I would like use a item category usage on the second item in SO (fisrt item of the BOM) to definite the item category of the third item in SO (the second item of the BOM) .
In T184 table SAP considere the header item to applicate the item category usage. Doesn’t applicate if the item category usage is applicate on item of the BOM category usage.
In other term, i would like that the item category of the material A70 (on the SD BOM) on SO can be to change according to the customer when i use the VD51
Thank for your help.
