What occurs when a data transform for concatenating first and last names is added to a flow action?

When a data transform for concatenating first and last names is added to a flow action, it runs every time the flow action is performed. This means that every time the user interacts with that flow action, the data transform is triggered, processing the input data accordingly. This behavior is essential in many scenarios, such as updating the case state or displaying the full name in real-time as the user is filling out the form or making changes.

In the context of Pega, flow actions are dynamic, and they rely on executing steps to gather, process, or display information whenever the user navigates through the application. By setting the data transform to run with each performance of the flow action, developers ensure that the output is always current and reflects any recent changes made by the user. This consistent execution is crucial for maintaining accurate information in applications.

Other options imply different conditions of execution that do not align with how flow actions and data transforms operate, such as limited execution to saving states or requiring a manual trigger, both of which would hinder the efficiency and accuracy of the functionality.
