Cross Business Unit PO access by Expense Auditor Role

1. When attempting to search for POs to match and create an invoice, users with the AP Specialist role are able to access POs from other BUs. 2. The user had access to only one BU. In addition to the AP Specialist role, the following roles were assigned: - Expense Auditor - Advanced Procurement Requester - Employee EXP - Enterprise Resource Planning Self-Service User 3. Upon testing, it was discovered that the Expense Auditor role triggers the access to POs from other BUs. 4. The user not only has visibility of POs from other BUs but can also process and create invoices. Is there a specific privilege within the Expense Auditor role that grants access to POs across all BUs?
