Payables Agent Stream Page - How to Restrict Visibility by Business Unit?

Summary:

User has access to only one Business Unit, but the Payables Agent Stream page/Invoice List displays invoices/documents from all Business Units. Looking for Oracle guidance on whether Stream visibility can be restricted by Business Unit. Example one user have access to specific BU like Italy business unit where he can create & view invoice for Italy BU but when he go through to payable agent stream page, he is able to see the Invoices across all Business.

We have create custom role to access the Payable agent. We have configured security according to the Payables Agent Getting Started Guide and security setup documentation. Final payables-agent-getting-started-guide.pdf describes the setup of custom roles, permission groups, and Business Unit data access required for invoice access.
