Conversion of foreign currency AR invoices so that they can be revalued accurately going forward

Summary:

What is the best way to handle the conversion of foreign currency AR invoices to ensure that they can be revalued accurately going forward?

Content (required):

We are converting unpaid foreign currency AR invoices. After conversion, Create Accounting will be run for these invoices, transferred, and posted in GL. The journals will be reversed in the same period, nullifying the accounting impact, since accounting for these will come through GL balance conversion.

These invoices will need to be revalued every period end. However, since the journals were reversed in the same period, revaluation cannot be done for these invoices.
