Oracle Payment Bank Account currency and ledger currency different

We have Business Case where
Bank account currency is loaded as USD for all non US countries
This is currently system limitation. For AP payment, Bank account currency should be same a ledger currency.
For example
India ledger has functional currency as USD
So India bank account, should have USD currency in system. Else we face error in non USD payments
Please note
multi-currency check box will be enabled.

Business functionally question :-
As understand actual bank account currency is not USD for APAC, EMEA and Latin countries. However, we have enable the multi-currency check box and keep it as USD.
