Which of the following is NOT a common method in Pega activities?

The choice of "Process-Start" accurately identifies a method that is not commonly used within Pega activities. In Pega, activities are primarily geared toward performing actions on data or managing the flow of the application. Methods like "Property-Set," "Page-New," and "Apply-Data-Transform" are integral tools used within Pega to manipulate data and control the behavior of the application.

"Property-Set" is used for setting values of properties, which is fundamental for data manipulation within activities. "Page-New" allows the creation of a new page instance, which is essential when initializing new data objects needed for processing within the application. "Apply-Data-Transform" is instrumental in transforming and mapping data between different objects, often used to change data structures or adjust values.

On the other hand, "Process-Start" is not an activity method; it is more of a step in the context of orchestrating processes or cases, rather than a direct function performed in an activity. Activities are designed to execute specific actions, and the other mentioned methods align with the core functionalities of activities, emphasizing data handling and object management.
