Thanks for getting back to us, @Bluemanta.

Let me share some information about the purchase report. To be able to view the source name, you'll have to add it from the column section. See the image below.

About the detailed line items, you'll just need to click on the PO to see them. 

With regards to the preferred vendor, currently, we're unable to pull up a specific report that way. You can pull up other reports (Open Purchase Order by Item) so you can filter it by Preferred Vendor. From there, export these reports in Excel to combine your desired data.

Please refer to these articles for more information:

• Customize reports in QuickBooks Desktop.

• Export reports as Excel workbooks in QuickBooks Desktop

Please don't hesitate to reply if you still have questions or concerns with the reports. I'll be around to help. Take care and have a nice day ahead.
