I can help you with running your Vat Detail report, @Kuwinamab.
Try to check the report date range that you set in the report. Manually select the date by selecting the calendar icon in the From and To fields. Then, check the Report basis. An accrual basis report shows income whether or not your customers have paid your invoices and expenses whether or not you have paid all of your bills. A cash basis report only shows income if you have received cash and paid your expenses.
Here's more information on how you can customize the Display, Filters, Header/Footer tab, and Fonts & Numbers tab: Customise reports in QuickBooks Desktop.
To save the same settings of the customised report, consider memorising it for future use. Here's how to create, access, edit, delete, edit, and set up a memorised report group in QuickBooks Desktop: Create, access and modify memorised reports.
Let me know if you have further questions about your reports. I'm always here to help. Have a great rest of the day!
