Approve input data with Validation Rules

DML is also used to define the rules that check whether input data is eligible to be processed by a Mapping Flow. These rules are called Validation Rules and are attached to Business Documents. The following graphic shows a Validation Rule as it might be displayed in Axway Mapping Services:

Similar to individual rules in the Maps, expressions in Validation Rules produce a value that is either yes, the data is eligible, or no, it is not. You can define one or more Validation Rules for each of your Business Documents. The document is accepted as an input only if every defined Validation Rule returns true.
