You use the VAT Statement Preview window to view a calculated VAT Statement before printing it.
The window contains a General tab, where you can specify which VAT statement you want to preview and which VAT entries must be included in the calculations, and lines that contain the actual statement as it will appear when printed.
On lines where the Type field contains VAT Entry Totaling, you can see the individual entries that make up the sum in the Column Amount field by clicking the AssistButton to the right of the field.
