When you select Post, Post and Send or Post and Print in Business Central, the default selection value is always “Ship and Invoice” for Sales documents and “Receive and Invoice” for Purchase documents.
For our customer’s workflow defaulting to Ship for sales and Receive for purchases was much better. We made new settings in Sales & Receivables and Purchases & Payables setups, that allow selecting new default values. In addition to this, we made it possible to override the default selection per user in User Setup.
