I have a problem where user choose item from integrated SAP catalog CCM 1.0 and add it to the shopping cart (EBP is 5.0).
When SC is displayed Category is different than in catalog.
I have only one backend (R/3 4.7) working in classic scenario.
During testing I copied material groups several times from the same backend with TCode R3AS but using FM BBP_CATEGORY_GET_GUID I checked that I have only one GUID per product grup in EBP.
User does not have default category.
In OrgStructure > Extended Attributes there is no limit on Product Categories ("*" for backend system). In this case EBP is always using alphabetically the first listed category.
If I list categories in Extended Atributes, system always use the first listed and not the proper one from the catalog.
