I've omitted the inclusive VAT for a vehicle purchased, I've updated all batches. How do I rectify this?
This appears to be an isolated case, but I've found 2 PDF manuals that you can use for this purpose. They're called VAT Guide and VAT Returns and Reports. I believe you will find all the necessary information related to VAT procedures.
You will also need a PDF reader to be able to open the files on your PC. You can pick anything on that list, but I would recommend using Adobe Reader.
