AR INVOICE NEED TO BE UNACCOUNTED

We have raised the export invoice through Order Management module. At the time of creating invoice, we have provided wrong Exchange rate, as it is refelecting in AR.

In order management module we can change the exchange rate from Back-end. But in AR module, we couldn't change it. We need to change the exchange rate by unaccounting the particular invoice.

So invoice unaccouting script needed. Please provide the source so that we can use it.
