Standard Class for QR Reference Number (QRR) and ISO Creditor Reference (SCOR) Validation in SAP?

[friendlycoder]

I'm working with Swiss QR-bills and need to implement validation for both reference types:

1. QR-Reference (QRR): a 27-digit numeric reference with a check digit calculated using modulo 10 recursive algorithm. This requires a QR-IBAN.
2. Creditor reference according to ISO 11649 (SCOR): a 25-digit alphanumeric reference that starts with RF followed by 2 check digits calculated the same way as IBAN check digits. This uses a normal IBAN.

Does SAP provide any standard class or function module that can:

• Validate existing QRR and SCOR references (verifying check digits are correct)
• Generate check digits for new references of both types
• Format references appropriately for Swiss QR-bills

I understand that the customization is determined via T049Q. I'm looking for the most efficient way to implement this validation without creating custom code if standard solutions exist.

Has anyone implemented either or both of these reference types in their SAP system? Any guidance on standard objects or best practices would be greatly appreciated.

Thank you!
