Came across the adjust exchange rate function in BC. It allows you to revalue foreign Bank, Customer and Vendor accounts at period end.
Very useful if at period end you have a lot of foreign currency accounts that you wish to revalue. By clicking Adjust Exchange rate, Select the currency that you wish to revalue the ok. BC will automatically revalue and post the revaluation in your general ledger. Note you must have your currencies setup with the accounts to post to.
You may get an error that the currency is not in the filter period. To resolve this you should ensure that FLOAT rates or your exchange rate is updated for that day.
