Fiori - Approve Purchase Order

Hi All,

In Approve Purchase Order App, user is able to see the PO which is created by them and also can see approve button, reject button and forward button. By right the user/creator should not see their own purchase order, only the approver can see and approve.

i checked in ECC, the user can view PO in business workplace inbox. is that why they can see their PO.

Please advice.

Thanks.
