Minimum check amount for Internal bank account

Hi ,

Need a clarification on how the minimum check amount in internal bank account is calculated in case if the bank is set for multi currency payment in Oracle Payables

For example. If the bank account currency is USD with minimum check amount set as  1  and bank account is used for multi currency payment.

If there are invoices for INR how the minimum check amount would be calculated. Is it 1 INR  ( In transactional currency) or is it  1USD converted to INR  (  68 Rs)/

Thanks.
