When you click the Delete button on the Tax Components [Sales] form, you will get a message warning you that you are about to delete the selected record. 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 record again.
There may be times when you try and delete a tax component and VisionCore will not let you. This can happen because the tax component is being use in subform area of an existing Tax Code record. VisionCore would display an error message explaining that the tax component could not be deleted due to referential integrity. The only way you could delete that record would be to delete all the associated Sales Tax line items that use that tax component.
The Delete button can be disabled so that other users can't delete any of the Tax Components [Sales] records. You can enable or disable the Permission check box for Delete Tax Components [Sales] in the Security form > Form Permission Tab under Sales Module (under Sales).
