Hi @sateeshp0869,

lData Transforms share the same name (e.g., SetDefaults). Pega climbs up the class hierarchy → executes the top parent Data Transform first. Then moves back down, applying each child class’s Data Transform. Each level can add or override values.

• Execution happens in sequence:

  1. Pega executes the parent (superclass) Data Transform.

  2. Then it executes the child class Data Transform.

• If both set values for the same property, the child value overrides the parent value (last one wins). How to Avoid Overriding (without using When conditions)

• Use Separate Properties for Parent & Child

  • Instead of setting the same property, define parent-level default property and then map/merge to child when needed.

• Use Append and Map to (for Page Lists/Page Groups)

  • If you’re setting on collections, instead of overriding, append new values.
