Unable to restrict the Product Manager for editing other Item Master Organization

Hi everyone,

I'm reaching out to the Oracle Community for some assistance with a security concern related to Security to Product management

My client has a user assigned with both the "Product Data Steward" and "Product Manager" roles, allowing them to create and manage items within the system. However, the user is able to view and edit items belonging to other Item master organizations, even though they shouldn't have access to data outside their specific organization.

We need to prevent this user (and any future users with similar roles) from seeing or modifying items that belong to organizations they are not explicitly granted access to. We want to ensure data security and maintain clear ownership boundaries within the system.
