Can the Local or System Currency be changed once transactions have started posting in the company?

Changing the Local or System Currency in SAP Business One after transactions have begun posting is not permitted. This restriction is in place because once transactions are recorded in the accounting books, they are tied to specific currencies. Changing the currency could lead to severe discrepancies in financial reporting and accounting integrity.

When transactions are posted, they create a historical record that reflects the currency conditions at the time of the transaction. Allowing changes post-transaction could result in confusion surrounding exchange rates and financial reports, making it difficult to maintain accurate and reliable financial statements.

Consequently, the system is designed to ensure the stability of the currencies used after transactions have been entered into the system, thereby protecting the integrity of the data and ensuring compliance with accounting principles. This is why the correct stance is that once transactions have started posting, the Local and System Currencies cannot be changed.
