1. SAP S/4HANA Help Portal
"Business Partner Category": This official documentation defines the three standard BP categories. It states
"You create a business partner in the category Organization for a legal entity... A business partner in the category Group cannot be the direct party in a business transaction." (Accessed under SAP S/4HANA -> General Functions for Key Users -> Business Partner).
2. SAP Note 2743348 - "BP of category 'Group' can't be used as Customer/Supplier/Contract Partner": This official SAP Note explicitly confirms that the 'Group' category is not intended for transactional roles such as customer or supplier
reinforcing that option B is incorrect.
3. SAP Education Courseware TS462 (SAP S/4HANA Sales - Upskilling): The unit on "Business Partner in Sales" details the BP concept
specifying that customer roles are assigned to BPs of category 'Person' or 'Organization'. It also distinguishes BP categories from BP roles (partner functions) like 'Sold-to party'.
