how to remove productcode on productpage?

hika copies the productname into the productcode field if left empty, so how to avoid this if i havent got a productcodenummer
thank u in advance

Hi,

To have that you can create a plugin using the function "onBeforeProductCreate" and "onBeforeProductCreate" and set teh value of the product code to ''.

Something like:
function onBeforeProductCreate($element, $do){
$element->product_code = "";
}
