Supplier profile change request automatically canceled after all approver approves

Hi,

We are facing an issue when updating the IBAN number for a supplier's bank account at the supplier site level. After the change request is approved, we receive a notification stating that the Supplier Profile Change Request was canceled due to the following reason:

Error: You must enter a valid value for the Account Number field.

The bank account country is Finland.

However, if we remove the IBAN number and then submit the change request, the request gets completed successfully.

Please assist us in understanding why the system is not accepting the IBAN number.

The IBAN we are entering is valid and contains 18 characters, in accordance with the requirements for bank accounts in Finland.
