About pre-activity or pre-data transform

[MaxonL16591286 (Maxon Liang)]

Hi in below course,

Event processing with action sets | Pega Academy

It mentions below:

///

• If the pre-activity or pre-data transform runs in the same context as the section refresh, configure them in the refresh section action.
• Modify the content of your pre-activity if needed when running it in the context of the refresh section.

///

Pls refer to attached picture.

may I know what are “pre-activity” and “pre-data transform”? could you help to explain the concept? Thanks.

@MaxonL16591286 I guess this is what the it is trying to say, minimize the number of calls to the server by wrapping them.

If this is your configuration, there would be 3 calls to the server.

To minimize the number of calls, the run data transform and run activity which are running before the refresh-this section action can be wrapped up inside it.
