restrict hiring manager to view position related to his department while creating job requisition

Summary:

restrict hiring manager to view position related to his department while creating job requisition

Content (please ensure you mask any confidential information):

There are two hiring manager- Hiring manager A and Hiring Manager B with different departments but same Business Unit.

I tried this with Position Security Profile secured by Area of Responsibility

Responsibility Type - Human Resource Representative

Scope of Responsibility - Department

when I added this AOR to both Hiring Manager A & B and under scope I selected their respective department from dropdown.

Now the main issue is Hiring Manager A is able to see only position related to his department, But Hiring Manager B is also only able to view position related to Hiring Manager A department.
