What is the distinction between a local action and an optional process?

The correct answer highlights the unique characteristics of local actions and optional processes in the context of case management and user interactions within Pega.

Local actions allow users to perform specific tasks or actions in the context of a case. A defining feature of local actions is that they require a primary return path, which means that after the local action is completed, the user must be directed back to the main flow or the next logical step within that case. This requirement ensures that there is a clear and structured route for users to follow, keeping the overall case progression coherent.

In contrast, optional processes do not necessitate a primary return path. They are designed to provide additional functionalities that can be engaged or skipped by users without affecting the flow of the primary case. Optional processes can be executed at various points within a case, adding flexibility to the case management experience.

Overall, the distinction between local actions and optional processes is crucial for understanding how user interactions are managed within Pega applications, emphasizing structured flow versus optional enhancements.
