Default Purchase Order Currency Conversion Rate in Multi-Currency Orgs when Currency Matches Ledger

Hi there,

Currently, it is a known issue that in a multi-currency org you cannot create a Payable for a Purchase Order that does not have any items received against it.  

This is because you cannot create a Payable unless the currency conversion rate is set, and it only becomes set once at least one item is received.

Please automatically set the currency conversion rate to 1 for any PO where the currency of the PO matches the currency of the ledger.  This rate will ALWAYS be 1 and should default to that so that Payables can be created even if an invoice is received before the items have been received.
