P43081 Filtering Requisitions and purchase orders

Hey everybody I hope that you can help me about this doubt.

I´m using approval routes at the time of requisitions and purchase orders generation.

My question is, how can I filter my two versions of P43081 program (Requisition and order approvals) to only show requisitions or orders awaiting approvals.

I have diferent statuses in the two versions, but the version of approve requisition still show purchase orders.

Requisition. PO Values.

Awaiting approval: 110
Approve: 130

Orders. PO Values.

Awaiting approval: 230
Approve: 280

Thanks.
