Need to restrict the Update or Correction at "Position Details page" when Requisition_id is present

Summary: If a requisition ID is present on a Position then Update or Correction at "Position Details" or "Request a Position change page" should be restricted through UI. This restriction should not be applicable for HDL as HDL updates should happen.

Attribute9 - Requisition Id (DFF)

Customer Name : Axis Bank

Code Snippet (add any code snippets that support your topic, if applicable):

The below rule is working.

But the issue here is edit access should be allowed through HDL but due to this rule HDL update also restricted. So, please guide me to create a rule to allow edit through HDL.
