Quite often, customers have multiple shipping addresses. In fact, it is not uncommon for a single customer to have dozens of shipping addresses. There is currently no way to automate the entry of shipping addresses to D365FF. This can't be done through RapidStart, nor can it be done via Excel (from the "Ship-to Address" list). We need to be able to do this.
You've been good enough to include a "Customer" spreadsheet in the RapidStart workbook, but the real data volume is typically in the shipping addresses.
