Accounts Receivables or Accounts Payable account cannot be associated in the manual journal Exchange Gain or Loss Account

Accounts Receivables or Accounts Payable account cannot be associated in the manual journal Exchange Gain or Loss Account


Dear All, 

I need to make two Journals as adjustments, one in my Accounts Payable and the other in my Accounts Receivable but it is not possible since there is this ERROR: Accounts Receivables or Accounts Payable account cannot be associated in the manual journal.

Is there any other way to make this adjustment since the difference is purely exchange/currency rate and my Accounts Payable and Accounts Receivable are zeroed/liquidated? I need a solution to trasnfer the "open" values from Accounts Payable and Accounts Receivable, that are not realy open since it is just a currency problem, to the Exchange Gain or Loss Account.  

Thank you. 

Kind regards,
