Buyers don't see any results in Communicate Purchasing Documents screen

Summary:1- How can we give the buyer access to the results?

2- Is this screen secured by data access? (In order that the buyer only sees the Processes for the Purchasing Documents for the Business Units he has access to).

Content (required):Via the Purchase Orders Overview pane in the Menu > Administration > Communicate Purchasing Documents a buyer is not possible to see any result, except for the Scheduled Requests he has submitted himself.

But for the processes that are submitted after the successful approval, the buyer does not see any result in this screen.

Most of the processes are submitted by user 'FUSION_APPS_PRC_SOA_APPID'.
