In SAP S/4HANA Cloud, the multiple address functionality of Business Partner (BP) allows one BP to have multiple addresses. However, when you assign a partner function (on the Partners tab) during sales document creation, the partner function can only use the BP's standard address.
· Solution 1
Create a unique BP for each unique address and give that BP the correct role (for example, customer).
· Solution 2 (available in S/4HANA Cloud 1811 and later versions)
Create multiple customers and assign them to the same BP. Based on such operations, you can pick a non-standard address of the BP during sales order creation.
· To assign multiple customers to a BP, use the Manage Customer Master Data app based on role “SAP_BR_BUPA_MASTER_SPECIALIST”.
· To create a sales order, use the Create Sales Orders app based on role “SAP_BR_INTERNAL_SALES_REP”.
