Exchange Rate Differences management in GR/IR Clearing

Hi,

When there is Exchange Rate Differences in the GR/IR Clearing run, the system automatically put this difference on the account set in Determination account > Accounts Payable > Exchange Rate Differences

We would like the system not to put the difference on this account (Exchange Rate Differences) but in the purchase order main account.

Is there a way to set that up somewhere or it is the only way to manage it?

Thanks for your help,

Elen
