Thank you @Jen_D for the clarification

The link you provided for the "Sources & Targets" methodology is broken

Nevertheless, the report tool should have an option to group the line items and show the total amount for each PO.

QB already does it when in Vendor > Purchase Orders

Asking the user to export the data to an Excel Sheet and manually hiding rows is more of the 80's - not the 21st century 

As for having columns in the report that are not part of the filtering ("Source Name") or sorting - I can send you hundreds of articles about how bad of practice this is. I hope Intuit is really listening because this reporting tool could use some TLC to make it more user friendly and intuitive. Specifically since the pricing model for QB has changed and the cost went up

After all - the purpose of a report is to provide the information I need in a single page view.

In fact, the very first statement on the page you linked in your reply shows as: "QuickBooks Desktop provides different reports that cater to your business needs."

Currently , the reporting tool is missing these needs

Thanks
