I made a small module sp_partner with some specific fields for partners and contacts
I want to add a menu item to upload functions in the existing menu structure: Sales/Configuration/Address Book : there I want to add "Contact functions". But that doesn't work. When I make a specific menu-tree (i.e. Sales addon/Configuration:Address Book) it works, but it's not what i want. Is it possible?

i tried :
<menuitem action="action_function_form" id="menu_function_form" parent="menu_config_address_book" name="Contact functions" sequence="10" />

But then i get following error:
"No references to sp_partner.menu_config_address_book" so it seems it looks only in my own module to find the parent menu

I tried to change de reference of the parent menu in res.menu_config_address_book but that gives the same error
How should i reference to the parent menu?

First your module needs to depend on the parent module in __openerp.py__ I think it is base in this case so it probably already does.

After that you just need to find the menu reference in the module you want which I think for address book is in base so if the rest of your parent code is correct

base.menu_config_address_book is where you want not res

you're right, it must be base.menu_config_address_book. now it works. tks!!
