Exchange Rate Date used for AR Auto Invoice(AGIS transaction)

Summary

Exchange Rate Date not using GL Date even though its on the Interface

Content

While importing an AGIS Auto Invoice, the GL date/Transaction date was populated on the Interface Lines. The expectation was that the exchange rate will be populated based on the GL Date. However the import failed because the exchange rates were not available for the Transaction Date. Whats the expected behavior here? How do we default the GL Accounting date to be chosen as the Exchange Rate date.
