[Solved] Sales Order Allocations disappear when a Shipment is confirmed - Bug or designed behavior?  

On our Sales Order screen, we're Allocating serial numbers using the Allocations button and pop-up, just like is done on the Shipment.  We can then create a shipment and/or an Invoice and the serial number Allocations are copied to these documents and stored in their respective DAC, SOLineSplit.LotSerialNbr, ARTran.LotSerialNbr, and SOShipLine.LotSerialNbr, respectively.  On the Sales Order and Shipment screens we can click the Allocations button and see the serial number that's been allocated.

However I just discovered that when the Shipment is confirmed, the Allocations on the Sales Order disappear! They continue to appear on both the Invoice and Shipment and if we create a Invoice after they have disappeared from the Sales Order (after we've confirmed the Shipment) they are copied over to the Invoice.

Now, I think we'll be able to work around this, but first I'd like to know if this is proper behavior we need to work around or if this is indeed a bug.  Our printed Sales Order form currently contains the serial/lot number, but now only works if we print it before we confirm the shipment.  Anyone have any insight or know where else the Lot/Serial Number might be stored wrt the Sales Order?  I know I can pull in the Shipment table, but that seems like it's not the most elegant solution.
