I have an object (Oppoortunity) that creates another object (Assessment) when the field "Assessment date and time" is updated. I only want the Object Assessment to be created once; the first time the "Assessmend date and time" field is updated.
I've added a checkbox "Has been edited" to the Opportunity object.
My process builder is as follows: When formula evaluates to true -
Immediate Actions: Create and Assessment Record, and Update Has Been Edited Boolean to true.
This Process flow is not working; i.e. the "Has been edited" box does not select as true when the date'time field is edited.
What am I missing?
