It worked with the domain and many thanks for your assistance

Hi,

If the issue that you are trying to resolve is of showing all data when the default filter is removed, what you can do is that, you can apply a domain for the corresponding menu action.

Sample:

<record id="action_inventory_line_tree" model="ir.actions.act_window">
    <field name="name">Inventory Lines</field>
    <field name="type">ir.actions.act_window</field>
    <field name="res_model">stock.inventory.line</field>
    <field name="view_type">form</field>
    <field name="view_mode">tree</field>
    <field name="view_id" ref="stock_inventory_line_tree2"/>
    <field name="domain">[('inventory_id', '=', active_id)]</field>
</record>

As it is an existing menu, you can inherit the action and add the necessary domain.

Thanks
