I am currently testing ERPNext.
I created some product items, however, there are a few where I did not enter a product code.
How can I add an item code to thoses items?
The items where an item code does exist can be edited by going to Stock -> Item -> Select the item and editing the name that appears in the upper left hand corner of the screen
However, for the items that do not have an item code, all I can edit is the name that I see on screen, and I can not find where to add an item code
A little help please?
