I am not sure about Process builder will work for this scenario or not but can anybody please tell me How to Notify the User If
OpenActivity related list is blank of the Particular Opportunity
(Opportunity.OpenActivities == Null) ? (Related list of OpenActivity is totally blank in Opportunity detail page)
I tried to create Process builder with Using Opportunity object & Task Object but i could not find the way to achieve this (In Task Process builder i used
Related To as in my criteria).
I have Professional Edition and i do not have permission to create Apex trigger or Workflow Rule for the same.
