Applying postal code validation in processes
Pega Government Platform includes an edit validate rule that verifies if the postal codes that users enter have the correct format. Ensure that processes capture correct postal data by applying this rule to flow action rules that you define in your application.
In Dev Studio, search for and select the flow action rule that you want to modify, for example, BusinessAddLocation.
On the Validation tab, in the Validate field, enter ValidatePostalCode.
Save the flow action rule.
