Create OT order if Item Branch has Stock Type U in receiving branch?

Client is upgrading from OneWorld Xe to EnterpriseOne 9.1  In Xe, if they enter a Transfer Order for an item where the receiving branch has Stocking Type U, the OT order line WILL NOT be created.  In 9.1, for the same conditions, the OT order line WILL be created. 

My understanding is that the U code would be used when the item has gone obsolete, but there is still some stock on hand.  So, it is okay to enter a sales order line, but it is not okay to enter a purchase order line.  The ST/OT order is of course a matched pair of sales order and purchase order.  It seems like you might want to allow Transfer Orders for these items, because you may be able to transfer them to another branch where they can more readily be sold, or otherwise dispositioned.
