I have discovered that if you use the Comment line on the Purchases, this report will bring up the comment line and list it as 0% or N/A on this report. I use the comment line to differentiate between branches of our company. Therefore when I used the report to try to check that I had not misplaced any VAT, it brought up a long list of purchases listed as 0% or N/A when they are listed at 20% VAT rate.
