There is a gap in the intercompany functionality that I wish to get supported by standard D365. It is the ability to generate an intercompany receipt (and PO invoice) for a sales order packing slip that contains order lines from multiple sales orders.

D365 has a standard feature to generate the PO packing slip (and PO invoice) from the sales documents however this fails when the user ships a consolidation WMS shipment and/or uses the "Arrange" function to group multiple sales orders on a single packing slip.
