Receipt Match Option - Exchange Rate Update

Hi,

We are matching invoices to purchase orders and receipts and have the Matching Option setup as 'Receipt'.

Regarding Purchase Orders entered in foreign  currency we have the following issue:

- We enter a PO by 1000 units and price = 1 - We select the Corporate Date when the PO was created 25/05/2013 i.e. 5

- We receipt the PO on the 02/07/2013 and the system defaults the Corporate Exchange Rate from the PO (25/05/2013). But we want the system to default the Corporate exchange date of the date that we are receiving the PO so the user doesn't need to update the exchange date at receipt level. In my example 02/07/2013.
