3503779 - Error FINS_ACDOC_CUST484 occurs in SSCUI 103379

When making configuration in SSCUI 103379 - Define Currency Settings for Ledgers and Company Codes, error FINS_ACDOC_CUST484 "You can't make currency type changes; postings exist in company code *" occurs.

SAP S/4HANA Cloud Public Edition

The error occurs because it is not possible to configure a new currency type for company code with postings existing.

It is not possible to add a currency type to a company code if there are postings because all existing data in table BSEG and ACDOCA will be incomplete, this will cause severe inconsistency in systems. Thus the message cannot be configured in this situation.

The definition of currency types for company codes is a fundamental configuration and must be done carefully at the very beginning. Once postings are made with the currency configuration, it is not possible to add, change or delete currency types anymore.

The functional currency is not an additional currency type but it is reusing an existing currency type. Therefore the functional currency could be changed though there are postings. But after a change of the functional currency all postings must be corrected. For specific postings e.g. from Advanced Foreign Currency Valuation the migration report for functional currency is not able to correct the journal entry completely. That's why a change of a functional currency is  a risk.
