Exchange rates are rounded to 6 digits when we completing AR transaction

Hi,

We are trying to convert AR transactions from legacy to Oracle and in the exchange rates columns, we are passing more than 10 decimals. When the invoice is imported, on the exchange rate column, I can see the 10 digits present as per what we have passed in FDBI file. But when I try to complete the transaction, the system is rounding the same into 6 digits. What we need to do to have the system accepts 10 decimals or more of exchange rates.

Regards,
