@DharanitharanR Data instances of Channel and interfaces are stored in the Pega Platform as rules, such as harnesses, sections, and portal rules. When deploying these rules to higher environments, you need to create a product rule file in the Development environment, which generates the artifacts to the repository and is used to promote the changes to other environments. The product rule must include all relevant rulesets and data instances except the application itself.
