Manage Procurement Agents Configuration

Summary:

Content (required):

Hello,

can someone explain the folowing questions regarding Manage Procurement Agents configuration?

1) Manage Requisition - Access to Other Agents' Documents

I suppose that this setiing is related to Process Requisition form (as the access to the other's preparer requisitions in Manage Requisition form is driven by functional security). When I set this option to Full, I'm able to see and process requisition lines assigned to other buyers. When I set this option to None or View, I'm not able to see requisition lines assigned to other buyers. So I wonder what is the difference between None and View.
