Return to Vendor on dropship didn't generate the accounting.

hi all

I got a problem in DropShip.

Problem how to happen, steps below

1.Create SO the Line is external

2.AutoCreate Purchase Order

3.Receipt Purchase Order

  the accounting in periodic costing

  Cr. Logical_Receipt (Clearing account)

     Dr. Logical_Receipt (AP Accural)

  Cr. INV

     Dr. Clearing

4.SO Line Closed

5.SO added on RMA Line, RMA Receipt

6.Return to Vendor

   the accounting in periodic costing

   Only got the Return to Vendor accounting

   Cr.Receiving Inspection(got the wrong type)

       Dr. INV

   No AP Accural accounting, No logical Return???

Anyone has the same problem in 11.5.10.2?
