Converting Existing Ledgers - Sales & Purchase Ledgers - Screen Design, Reports and Statements

The only mandatory change is to provide an option on the accounts maintenance screen(s) to enter the currency code for the account. You may want to amend the ledger enquiry options to include currency values (for when the customer/supplier enquires on balances or transactions)

Report changes are unlikely, except for potentially including the currency code for reference purposes, as the reports are for internal use you will be primarily concerned with base values.

Statement changes are also unlikely. A run-time parameter controls whether details are printed in the base currency or the currency of the account.
