GL Clearing through F-03

Hi Gurus,

I want to clear some items in Shipped but not Billed GL Account.

For eg.

While shipping we credited in EUR currency amount 100

While Billing we debited in USD currence which is equivalent to 100 EUR

Both entries made on 4th of month.

If i want to clear these two items on 10th, system is picking exchange rate of 10th which is creating difference and not allowing me to clear.

Please revert, how to solve this issue

Thank YOu
