Adding new validation steps

If you are using customized SEPA schemas, you must customize the framework, and possibly the validation maps, that the validation framework calls.

Here you will find a description of how to add new schemas or customize existing ones. Even if you are using only the existing SEPA schemas, you may want to add a new map step. One example could be that your overall implementation requires you to process SEPA messages that only contain a certain number of payment transactions, which is less than the number allowed by SEPA.

Creating a new map step involves updating the validation framework maps to:

Optionally extract a subset of information from the message to make downstream mapping more straightforward, with the use of a NVP WorkTemp. See About NVP WorkTemps(s).
Set up the new step as a call to a functional map.
