3733976 - IBAN auto-derivation when bank account is '-' and blank not allowed; different IBANs not possible for same bank key/account

• The system automatically derives an IBAN when the Bank Account field is entered as “-” (hyphen).
• Blank entries for the Bank Account field result in an error and prevent IBAN creation (including in transaction TIBAN).
• Changing the derived IBAN updates existing vendor/business partner bank records.
• Duplicate key entries are not allowed for the same Bank Key and Bank Account.
• A business partner record exists with the same Bank Key and Bank Account but a different IBAN; attempts to create another such entry are rejected.

• SAP ERP
• SAP S/4HANA
