Receipt routing blanks out unit cost and extended cost in F43121

Hello,

Scenario is as follows when we use the option of "Price at Receipt" functionality.

1. Enter a PO for an item with a price of "X"

2. Move the PO through the statuses

3. Price is changed to x+n in the Supplier item catalog (P41061) before the receipt

3. PO is received in P4312 with "Price at Receipt" turned on

     - Line is updated in F43121 with unit cost and extended cost

     - Items entered into routing

     - Item price is reflecting with a unit cost of x+n

4. Move the items through the stages in routing and finally to stock

5. In F43121, the document number (OV) gets updated (overridden) , but the unit cost and extended cost for that line disappears.
