Unit of Measure missing in Shopping Cart
Currently, we have implemented BADI BBP_CATALOG_TRANSFER to map Unit of Measure from z-table, based on shopper's backend system. The mapping is done successfully when it return to Shopping Cart (e.g. PAC (catalog UoM) -> PAK (backend system's UoM)).
When I am at "Step 2: Shopping Cart", I've tried to view Item details (click on Magnifier icon in 'Action' column), and I noticed that mapped UoM 'PAK' is still there. However, when I click on 'Check' button, I found that the following error message returned:
"Enter a unit of measure"
I am wondering why UoM will be missing, and I notice that when the time I click on 'Check' button, it went through to BADI BBP_DOC_CHANGE_BADI of Method BBP_SC_CHANGE. I have checked import table IT_ITEM and found out that IT_ITEM-UNIT is missing.
Although I have put an breakpoint in Method BBP_SC_CHANGE, I discover that IT_ITEM-UNIT is missing ONLY when I click on 'Check' button from Item detail page above.
Is there any steps missing in config, or otherwise?
