Custom role to access "Supply Order Lines" based on BU or Inventory Org assigned to the user

We have a custom role for Warehouse Manager which gives access to SFO work area to view and Manage the Supply Orders. However, irrespective of the assigned inventory organization in the user data access for the custom role.

This issue impacts multiple users in the live system. We need information on which data security policy / privilege should be updated to restrict the access based on assign Business Unit / Inventory Organization. As of now, all users can see all BU supply orders which is not appropriate.

Attached is the custom role privileges, including the DSP.
