I need to modify or add new items in the combo box of the product type cul me appears when you add a new product, by default you have 3, the storable, consumable and service. I want to change this to just 2, one product and another saying that says licenses. This is according to in product.py file where you have to change, but I already did not show changes, and even reboot the server and not so visible. Stand them to modify codes:
in the class product_template (osv.osv) Variable class _columns
change this
fields.selection ([('consumer', 'Consumable'), ('service', 'Service')])
Variable _defaults change in this
'type': 'equi'
if it is not the only file you need to change to see the change of the combo box.
