Topic: Adding new quantity
I have a simple database with the partnumber and the quantity of some products. When I insert an excel file which contains new records (partnumber and qty) and existing partnumber with quantity in a tablegrid how can the new qty added in the existing qty of the partnumber. Example when a new order arrives so it adds the new ordered qty in the database. A simply example would help. It has been a week that I can not find the solution so please your help.
