What is a Validation Rule?
Definition
A Validation Rule is a rule applied to a specific field link in a Map that controls how the field value is validated or transformed during document processing.
Validation rules can be set at different levels — Global, Reseller, Partners, Customer, or Custom partners — giving each level the ability to override or supplement rules set above it.
Where to Find It
Validation Rules are configured directly on map links inside a Map Configuration. Navigate to: Advance Config → Maps → click ··· → Config on a map:

Maps list — ··· actions menu (Edit / Config / Export / Delete)
In the Map Configuration, right-click (or click the context menu) on any link row to see Set Source Validation and Set Destination Validation:

Map Configuration — link context menu with Set Source Validation and Set Destination Validation options
How to Add a Validation Rule
The Add Validation dialog shows the field path and document type. Select the Customer tab to add a rule for your own account. Choose a Rule Type:

Add Validation dialog — Customer tab, Rule Type: Optional (value is optional)
Search for a rule type by name to see available options and their descriptions:

Add Validation — search "har" showing AddPadChar and HardCode rule types with descriptions
After selecting a rule type, configure its parameters in the Rule Configuration section:

Add Validation — HardCode rule selected with "Hardcode value" field showing "abc"

Add Validation — click Save to apply the rule
Once saved, a yellow dot (●) appears on the link row in the map to indicate a validation rule is active:
