Hi,

Here are two effective methods:

Using Access Groups and Record Rules:

Step 1: Create Access Groups:

Create two new groups: "Dept A HR Manager" and "Dept A Supervisor."

Assign relevant users (HR Manager and Supervisor for Department A) to each group

Step 2: Define Record Rules:

Domain: [('department_id', '=', a_department_id)] (Replace a_department_id with the actual ID of Department A)

Groups: Choose "Read access" and "Write access" for both "Dept A HR Manager" and "Dept A Supervisor" groups.

Hope it helps
