I am trying to update a field in my child record automatically when a parent record gets deleted. I have 2 objects, 1. Team 2. Player. I have lookup relationship between both objects. Team is parent object. There is a checkbox field in player object called, is free agent. Each player is related to a team. What i want to do is, I want to check the "is free agent" check box once the related team to this player gets deleted. I am trying to do it using process builder. I cannot use apex triggers. Because I am practicing salesforce built-in UI tools.
here is what i have tried.
Checking criteria if lookup field is empty in player object
