It is not a best practice to call an activity from Data Transform rule. 

You may try the function pxExecuteAnActivity or similar code, if your use case demands that.

Hi Lavanya,

You can have a look into the use case that i created for another user over here which might be helpful to achieve your requirement if you still want to call activity from data transform.

Hi,

Try the below function

Param.Activity == @Utilities.pxExecuteAnActivity(PageName,yourActivityName)
