Yes I know you can change the name in the product module under admin the problem is if that product name already exists obviously it cannot be listed twice. And you cannot delete the incorrect name because it is associated with a closed PO. Here are two examples
Componentid Componentname Manufacturername Componenttypeid Partno Comments
8706 DELL Latitude E6420 -2 - 1 - -
3337 DELL Optiplex 960 -2 - 1 - -
