3227634 - Error: "Field 'Account Currency' contains an entry, although it is hidden"

You attempt to change an account type to 'Cash Account' with sub-type 'B' or 'S' in the 'Manage G/L Account Master Data' app (ID F0731A) but when saving you encounter error message  "Field 'Account Currency' contains an entry, although it is hidden" (Error FH738)

S/4HANA Cloud

The account currency field is suppressed for cash accounts with sub-type 'B' or 'S', as the account currency field is always filled by the company code currency.

When posting to such an account, the specification of a house bank account is required. The transaction currency check is done based on the house bank account provided in the document, meaning the G/L account master is no longer responsible for this; hence any transaction currency can be used.

Ensure that the account currency and company code currency are the same for any cash account with sub-type 'B' or 'S'
