SAP QM Inspection - Drop Shipment with Partial GR

Hi,

We have configured the system for QM Lot generation on GR against PO.

Now we have come up with a requirement that Inspection to be carried out before GR. I assume that SAP covers with the Drop Shipment process. I have following concerns and how to address them:

The link

https://blogs.sap.com/2020/07/13/quality-inspection-in-drop-shipment-process/

provides all the details but I cannot find any link between the PO and the Inspectio Lot created.

I have following 02 queries for now:

1. How would i link the PO with the Inspection Lot created for tracking and reportign purposes?

2. If requirement is for partial GR against PO from time to time, then how to handle that through Drop Shipment process, such that for each Lot created prior to GR is linked with same PO and different GR# (MIGO Doc No.)
