I used ir.actions.server model for add an option in action menu item.

Main purpose for using this is to run python code from here.Here i don't want to return a tree or form view here , so i used this method.

I need to add an option only in vendor bills form, but the option is set both invoice and supplier form.

<record id="account_invoice_accrual_entries_vendor_bill_non_po_action"                 model="ir.actions.server">

            <field name="name">Accrual Entries</field>

            <field name="model_id" ref="model_account_invoice"/>

            <field name="domain">[('type','in',('in_invoice'))]</field>

            <field name="state">code</field>

            <field name="code">

                  if records:

                    records.action_accrual_entries_vendor_bill()

            </field>

        </record>

        <record id="account_invoice_accrual_entries_vendor_bill_non_po" model="ir.values">

            <field name="model_id" ref="account.model_account_invoice"/>

            <field name="name">Accrual Entries</field>

            <field name="key2">client_action_multi</field>

            <field name="key">action</field>

            <field name="model">account.invoice</field>

             <field name="value" eval="'ir.actions.server,' +                     str(ref('account_invoice_accrual_entries_vendor_bill_non_po_action'))" />

        </record>

This is the code i try to add domain only for vendor bills. But the option visible in both vendor bills and customer invoice.

anyone knows what is the mistake in my code .??
