When you click the Delete button on the RMA's form, you will get a message warning that you are about to delete the selected customer RMA. 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 customer RMA again.
The Delete button can be disabled so that other users can't delete any of the RMA records. You can enable or disable the Permission checkbox for Delete RMAs in the Security form > Form Permission Tab.
The little Folder button in the Line Item Detail next to every Item No will open the Line Item Options form where you can choose to delete the selected line item. When this form opens click the delete button to delete the line item.
