Confirm receipts for PO Matched Invoices

Summary:

Confirm receipts for PO Matched invoices

Content (please ensure you mask any confidential information):

When Invoice 1 is matched to a PO and Confirm receipts is run, the system sends an email requesting the user to confirm receipts. Later Invoice2 is created and matched to the same PO, and confirm receipts is run again, but no email is sent. Why is the second confirm receipts email not sent to the user?

1. If the user clicks the "Receive upto invoice amount" from the First email, does the system receive only the amount related to Invoice1?
2. After the user takes action on the first email, will the system then trigger the second confirm receipts email for Invoice 2?
