Hi,

For making the menu, Sales -> Reports -> Sales, visible for the users "User: Own Documents Only" and "User: All Documents", what you have to do is that you have to add this group to the menu.

It can be done either from the User interface or from the code.

From Code:

create a xml file and add this code.

<record model="ir.ui.menu" id="sales_team.menu_sale_report">
    <field eval="[(4, ref('sales_team.group_sale_salesman'))]" name="groups_id"/>
</record>

From the UI:

Activate the developer mode and navigate to Settings -> Technical -> User Interface -> Menu Items, then search the corresponding menu, ie, Reports menu and open it and in the Access Rights tab add the group.

Thanks
