If I set Delete on, user may try to add a delete record again by mistake.
This will quite often to happen when editing the Orderline .......
Because user think when he/she ask for delete, the record should
disappear.
Should I avoid the Break Key error and set the primary key backward
to normal index key and allow duplicate?!
seem will be more worse..........
