When a receipt is posted against a direct ship (a.k.a., drop ship, buy-to-order) purchase order, the posted quantity is also reflected in the sales order line item's Receive Now. However, the sales order's packing slip does not get posted after the purchase order packing slip.
Is this by design or am I missing a control point somewhere?
If it is not by design, where is the bit of code that causes the posting of the sales order packing slip? I've been through PurchFormLetter and PurchFormLetter_PackingSlip dozens of times and cannot locate it.
