I am trying to ensure that all new Leads are processed by the Active Lead Assignment Rules upon creation.
I have configured the Page Layout properties as follows:
Page Layout > Layout Properties > Lead Assignment Checkbox
Show on edit page: Checked
Default: Checked (True)
The Problem: I want this to be mandatory. I tried hiding the checkbox from the user (by unchecking "Show on edit page") while keeping the "Default" set to True. However, when the checkbox is hidden, Salesforce seems to reset the Default to FALSE, and the Lead is simply assigned to the creator instead of being routed by the rules.
What I've tried:
Setting the default to True (works only if the checkbox is visible to the user).
Hiding the checkbox (causes the assignment to fail/default to the creator).
Looking for a "Required" property (the checkbox is not a standard field, so I cannot find it in the field list to make it required).
Question: Is there a way to force Lead Assignment Rules to run on every Lead creation via the standard UI without allowing the user to uncheck the box? Or is there a workaround (like a Flow or Apex) that can "re-check" this logic during the save process?
