Oracle fusion Purchasing

Dear Team,

I have a two scenario 's as below ,kindly go through and give your comments,

1.I created a blanket purchase agreement with option enabled "Automatically generate Orders" and "Automatically submit for approval" due to which while creating the Purchase requisition , if we give this agreement details if the item is present in this agreement PO will be created automatically without buyer or procurement agent intervention

2.With the same agreement I am creating PO manually from process requisition once PR is created without agreement details.

Now my question is how to identify the purchase orders that got created automatically and manually.
