Connecting Redressing PO with shipment PO

Problem statement : Redressing PO in not in scope in TrackIt, so the redressing PO can only show in Lastmile after the Goods are in QI status (movement 101).

Users need to have the PO shown in Lastmile when it is created so that then can monitor the redressing status They agreed to enter the shipment PO when they create the redressing PO in SAP.

Acceptance Criteria :

User will enter the shipment PO number in SAP "Our reference" , so  we can show the PO number under "Original Shipment PO" 

and when there is a shipment PO number entered, we show the redressing PO as "in redressing"

1. Can we check what we have in  SAP "Our reference"?
2. Can we display the redressing PO when it is connected to a shipment PO?
3. OR we should rename  "Original Shipment PO" to "Redressing PO" and ask user to enter the redrssing PO in ?
