  • Integration Capability: They integrate seamlessly with external systems or services through connectors, facilitating data exchange and workflow orchestration.
  • Execution Context: Activities can be triggered by user actions, events, or automated processes like flows and agents, supporting both interactive and batch processing scenarios.

9. What is Flow Action in Pega?

In Pega, a Flow Action is a user interface component that allows users to interact with and progress through a business process or flow. It represents a specific step or task within a larger workflow and enables users to input data, make decisions, and move the process forward.

Key characteristics of Flow Actions in Pega include:

  • User Interaction: Flow Actions provide an interface for users to perform actions such as entering data, making selections, or submitting forms within a business process.
  • Integration with Processes: They are integrated into flows, where they represent individual steps that users need to complete to advance the flow to the next stage.
  • Configuration: Flow Actions can be configured with predefined behaviors, validations, and conditions based on the requirements of the business process.
  • Form Generation: They automatically generate forms or screens for users based on the defined fields, sections, and layouts, facilitating a consistent user experience.
  • Event Handling: Flow Actions handle user events such as button clicks, form submissions, or decisions made during the process, triggering corresponding actions or transitions in the flow.
  • Accessibility: They ensure that users have appropriate access rights and visibility to perform actions and progress through the flow based on their roles and permissions.
