Question

Hi,
I'm trying to use the Set External PVs Activity smart service. There is the process variable(boolean) which is set to false in 50 instances. Now I want to set the value of that process variable to 'true' in all those 50 instances. I'm trying to do so using this smart service. However its not working and null pointer exception is thrown. Can anybody tell me what value shall be provided in Operations and Target PVNames in the Input tab of this smart service?

Thanks in advance!...

You can use messages instead. Check docs.appian.com/.../Send_Message_Event.html and docs.appian.com/.../Receive_Message_Event.html .
