Question
When Amending a used qualifying vehicle in Vehicles > Vehicle Costs > Amend Used, the "Tax" field is able to be amended but once you click off it then clears itself - how can I resolve this?
Answer
To resolve this you will see there are two fields on the left of the screen labelled"company Tax Number" and "Tax number". If these two are the same then deleting "Tax Number" will resolve this issue.
If both these fields are identical then, then this will automatically be treated as Internal and remove any Purchase Tax.
