Summary :
SAP Note addresses the enhancement of the "IBAN Valid From" field's prefill functionality within the Bank Account Management component. Initiated due to a program error, the field was previously auto-filled with SY-DATUM upon IBAN generation via the SAP button but remained unfilled when manually entered. The correction ensures that whether IBAN is generated or entered manually, if "IBAN Valid From" is empty, it will now be auto-filled with SY-DATUM. Additionally, clearing the IBAN will automatically clear the "IBAN Valid From" field. Implementation requires applying the note or installing the latest support package stack.
