When getting this error, you are probably trying to validate a payment journal, where you are using a reference payment type.
When using reference payment types, there are certain things that must be met:
- The payment reference Id must be filled
- The length of the reference Id must meet the demands for the current receiver’s country
- The Reference Id must comply with the modulus check for the current receiver’s country
If it is not possible to comply with these requirements, you need to select another payment type for the current transfer.
