purchasing scenario

Dear all,

we have a the below purchasing scenario, which i am not sure how to address it on SAP

We place a PO for an import vendor, and we are taking care of the transportation and the insurance (third party)..

During the shipping, some quantity is lostu2026 now we need to do the following:

1. We need to receive the actual quantity (less than what is in the PO) and mark the line as fully received (this is fine).

2. We want to charge the insurance company about the loss, and we want this to be recorded in the PO history.

3. The vendor should be paid fully as in the PO (it is not his fault that some quantity is missing).

Ddo you know how to apply this on the SAP..

thank you
