This form will list all the Purchase Receipts created after processing a recurring transaction for all the purchase receipts selected, thus giving you summary on the newly created purchase receipts.
In the Order Number field, the only entry field, enter the Order Number specific to the Purchase Receipts created. There is also an ellipse button to the left of the Purchase Receipt ID that when clicked will bring you to the actual transaction.
