When you click the Delete button on the Tax Types form in VisionCore, you will get a message warning you that you are about to delete the selected tax. You have the option at this point to cancel or go ahead and delete the selected record. If you confirm that you want to delete the selected record, VisionCore will delete it and there will be No way of retrieving that tax again.
The Delete button can be disabled so that other users can't delete any of the tax types. You can enable or disable the Permission checkbox for Delete Tax Types in the Security form, Form Permission Tab.
There may be times when you try and delete a record and VisionCore will not let you. This can happen because the record is being used in several other areas of the program. For instance, if you try and delete a tax that is being used in a Tax Group, VisionCore will display an error message explaining that the record could not be deleted due to referential integrity. The only way you could delete that tax would be to delete all references to it in the Tax Groups form first.
