Why doesn't the Sales Order number come through to the Posted Sales Invoice when a Sales Invoice is created and the Get Shipment Lines function is used to complete the invoicing process? The Posted Sales Shipment has it. Is there a way to make it come all the way through to the Posted Sales Invoice?
Because with this process you could add shipment lines from different orders to a single invoice. When you post and ship from the sales order it is one to one, so it populates at that time.
