Purchases by Supplier Detail Report

Hello there, Cathinarush. There are a few things you perform to generate them.

As long as we have recorded purchases in QuickBooks Online and haven't deleted them, they will appear in the report when customizing the dates and including other necessary details. Aside from the report date, ensure that there are no other filters applied to the report.

 Alternatively, you can check the audit log to see if there records of deletion. Note that you'll have to manually recreate the deleted entries.

If there are none, I recommend accessing your QBO account in an incognito or private browsing window. Sometimes, browser-cached data can interfere with QuickBooks functionality.

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift +P
• Safari: Command + Shift + N

Then, you can clear your browser's cache if you no longer have trouble with the report. You can also use a different web browser that is supported and up-to-date.

Additionally, you can check this article for more details about personalising report in QuickBooks: Customise reports in QuickBooks Online using modern view. 

I'll be around to help if you have follow-up concerns about viewing data in QuickBooks reports.
