Decision tables

The Decision tables tab lets you manage DMN decision tables for automated business decisions within the case definition.

A decision table encodes business rules as a structured table: given one or more input values (process variables), the table evaluates the matching rule and returns an output. Decision tables follow the DMN (Decision Model and Notation) standard and are executed automatically as part of a process.

Use decision tables to separate business logic from process flow — for example, to determine eligibility, calculate a fee, or classify a request based on its attributes.
