What type of rule requires explicit execution to perform actions in Pega?

Procedural rules in Pega are designed to define a sequence of steps or actions that must be performed explicitly within a flow. They are typically used to encapsulate business logic or instructions that need to be executed in a specific order. This means that the actions defined in procedural rules do not occur automatically but rather need to be triggered by a user or a specific event in the system.

In contrast, declarative rules automatically update data or perform operations based on conditions without requiring manual triggering. Policy rules are typically related to business decision-making and do not inherently involve procedural execution. Workflow rules, while they manage the flow of processes, also include behaviors that may not necessitate explicit execution on the part of the user.

The distinguishing feature of procedural rules is their requirement for explicit execution, making them essential for scenarios where precise control over the sequence of operations is necessary. Understanding this can help in effectively utilizing and managing these rules within Pega development.
