Hi All,

We are testing Oracle apps Mobile functionality. Connectivity has been achieved succesfully and the Mobile apps is working successfully. when a Buyer creates a PO from his Desktop and submit for approval  , the PO goes  to his manager ,managers approves the PO.via Approvals Apps  But  in Procurement Apps , we cannot see the headers information but can see only line details . Can anyone please suggest , how one can see the Header details as well.
