Revenue mismatch between Project Contract and RMCS

Revenue mismatch between Project Contract and RMCS

Content

We have noticed that for a foreign currency (e.g. USD) project contract, the revenue which get generated in contract currency is finally converted to ledger currency (e.g. GBP) using the exchange rate of transaction date in project contract whereas when this revenue is transferred to RMCS it is converted to ledger currency using the exchange rate of contract start date. No where this revenue variance is captured in RMCS. How can we force the project contract to generate the ledger currency revenue using a fixed exchange rate (exchange rate of contract start date) throughout its contract life cycle.
