Partial deliveries and partial invoices in P2P

Hello all,

what are the options for viewing partial deliveries and partial invoices in a purchasing process (P2P)?
We would like to determine the open order quantities for which order processes invoices / credit notes from creditors are still missing. The determination of the open order quantity is not easy to implement because we have partial deliveries and invoices for many order items that cannot be compared 1:1.

Best regards
Kevin
