- Search for Bank ID.
- Choose Edit.
- Navigate to Bank Accounts.
- Add the details and press Save.
The error "Combination of Bank, Company and Bank Account already exists" appears.
Cause
The system currently checks for duplicate IBANs across Bank Accounts.
It is no longer permitted to add a bank account with an IBAN that is already being used by another bank account.
Resolution
The code logic has been changed after 2018 and you cannot add a bank account with an IBAN that is already used by anther bank.
The system works as designed.
