Hi @kruthika ,

I could find a pair of old replies from RnD regarding this:

1. “As the Supplier invoice matching in the PO
   •    Stage payments only relate to matching of amount (not quantity) which is each stage is approved upon payment.
   •    Normal Payments there relates to matching of quantity which is purchase order receipts.
   So considering the above stage payment logic supplier invoice not considers quantity at all when invoice matching even after the final stage payment.
   Approve the last payment step we allow to do after the PO receipt because the report for Received not yet invoiced is related to amounts that are connected to received and invoiced quantities means that it is difficult to calculate an amount on this report that relates to stage payments as they only refer to amounts, not quantities. Therefore amounts related to receipts will remain on this report until the last stage payment is approved.
    This means that when the last stage payment invoice is approved, the “close date” on connected PO receipts should be set so that these receipt lines will be removed from the received not yet invoiced report.
   And other benefit is, if we approved the last stage payment without PO receipt and do the Invoice matching then we already pay total amount to supplier without goods receiving that why the last stage payment not allow you to approve without the  PO receipt.
   According to the stage payment logic it is not able to record the invoiced quantity on the PO receipt.
   The Stage payments functionality is mainly aimed to support companies that require procurement of many large assemblies with long lead times and high cost outlay. Both non-project and project oriented companies could require staged payment.
   For these companies one would make stage (partial) payments for each approved milestone. Note that stage payments most likely are approved before the actual purchase order receipt is made. It should then be possible match these stage payments on a supplier invoice”
2. “As there is no receipt qty involved in the stage payment functionality, we cannot update the invoiced qty correctly if one of the invoices gets cancelled when there are multiple invoices exist for a particular receipt.
   So updating the invoice qty at last receipt is also not possible.”

They recognized this as an Enhancement Request and probably they will consider this when doing other changes in the area of stage payments

Also, probably in your Supplier Invoices for the stage payments you didn’t provide neither the Invoiced Qty, and also Invoiced Qty in Purchase Receipt is also showing 0 value when using Stage Payment.

I hope this helps
