# Validate Logic and Debug Data 360 Runtime Definitions Faster with Data Preview

Validate definitions during the design phase by previewing node-level data transformations. Confirm that configurations meet business needs and identify logic errors early. Data preview is available for Data 360 and CRM Analytics definitions. Debug configurations in a controlled environment before saving or running definitions.

**Where:** This change applies to Lightning Experience in Professional, Enterprise, Unlimited, and Developer editions where Data Processing Engine is available.

**How:** In the Data Processing Engine builder, click **Generate Data Preview** and configure settings to view node output records. Use input variables to simulate runtime conditions and apply filters to isolate specific data. To verify transformation, inspect node output records and trace data flow across nodes.
