GL Report Open Balance should be in Current exchange rates

Hi All,

Kindly suggest the appropriate solution on the below requirement-

Scenario:-

My client provides the services, after completion of the half work done client post JV towards unbilled revenue & Unbilled Revenue Receivables account

Suppose 50 Hour work is done out of 100 hour work than for 50 Hour client post JV of 50 USD through user exit in FB50 t code

Dr        Unbilled Revenue Receivables              50 USD

Cr        Unbilled Revenue                                      50 USD

And when billing request is created for this 50 hour work then, they post the reversal entries through T code FB50, it is the reversal of the above entry posted

Dr        Unbilled Revenue                                      50 USD

Cr        Unbilled Revenue Receivables              50 USD

Requirement of the Client:-

Scenario 1.

Suppose for the month of April total value of JV posted is 50 USD for which accounting document is passed with exchange rate of 52 INR.

The requirement is that at month end if system is showing the open balance of 50 USD & exchange rate is 55 INR than system should re-determine the INR value of G/L with new current exchange rate & show the balance. 

Kindly suggest the possible solution on the same!!
