For a Remittance -inward registration, the Test Key received is the sum of all the code value of the parameters Maintained for the Instrument Code and External Bank code (Inter-bank remittances). If no Test key maintenance is available, test key validation is skipped.

The External Banks for which Test Key Maintenance is present for the instrument code and issuer code, the Remittance-Inward is not saved without the Test Key being validated.

The Test Key validation fails for Remittance Inward, if the corresponding code value of the (any) parameter is not maintained.
