In Dynamics 365 and AX 2012, When a user creates a general ledger transaction and change the rate on line 1, they would like the system to have the ability to apply the same rate to all the lines for the voucher.  For example, if line 1 has exchange rate of 100, then all succeeding lines that belong to the same voucher in the same currency should have the same exchange rate setup.  What is currently happening is that the system is defaulting in the exchange rate from the Exchange rate setup based on the transaction line.
