how to inherit or replace the product object in the customer invoicing form?

class account_invoice_line(osv.osv):
    _inherit = "account.invoice.line"
    _columns = {
            'your_new_field': fields.many2one('your object name', 'Field name',),
            }
account_invoice_line()

Add in .xml file

<record id="invoice_customer_invoice_form" model="ir.ui.view">
    <field name="name">account.invoice.customer.form.test</field>
    <field name="model">account.invoice</field>
    <field name="inherit_id" ref="account.invoice_form"/>
    <field name="arch" type="xml">
            <xpath expr="/form/sheet/notebook/page/field[@name='invoice_line']/tree/field[@name='product_id']" position="replace">
                <field name="product_id" on_change="product_id_change(product_id, uos_id, quantity, name, parent.type, parent.partner_id, parent.fiscal_position, price_unit, parent.currency_id, context, parent.company_id)" invisible="1"/>
            </xpath>

            <xpath expr="/form/sheet/notebook/page/field[@name='invoice_line']/tree/field[@name='name']" position="before">
                <field name="your_new_field"/>
