Also, I am getting error while trying to build a new function. My Activity has got no IN parameter- it will pick values in runtime, while a work item is open. It needs to return a TrueFalse Value to the when condition. ***Edited by Moderator: Pallavi to update platform capability tags*** Pega Platform System Administration Data Integration Java and Activities Technology Services System Architect × Close popover Facebook Twitter Linkedin Email Copy Link Copied!
