Posting Open Balance to a All Currencies G/L Account

Hi All,

I have a situation for which some assistance is required.

I am trying to post opening balance to the G/L bank account which is defined as ALL Currency.

On the G/L the system show that Account as Currency = All Currencies and adjacent to the Balance it shows that currency ID as GBP.

This account is a $ Account and I want to post the Open Balance in $. However, when I try to create the Open Balance the FC columns are disabled.

What am I missing?

Best regards

Earl
