What is the diffrence between Automation rule and Activity?
Automation rules react to conditions automatically; Activities are called explicitly and execute step-by-step procedural logic.
Automation Rule
- A declarative construct that triggers automatically based on conditions (data changes, events, or time-based triggers)
- Runs without explicit invocation — the platform watches for the condition and fires it
- Configured via a when condition + action pairing
- Best for reactive logic: “when X happens, do Y”
- Lower-code, easier to maintain, and runs in the background
Activity
- A procedural construct — essentially a step-by-step method made up of discrete steps (Java, utility functions, property sets, etc.)
- Must be explicitly called (from a flow, another activity, a data page, etc.)
- Gives you fine-grained control over execution order and logic
- Best for a defined sequence of operations
- More powerful but heavier — considered a legacy pattern in modern Pega (App Studio favors Data Transforms, automations, and case-level logic instead)
