Chirag,

Technically, its name_get() method you have to override().

Thanks.

@api.multi
    @api.onchange('product_id')
    def product_id_change(self):
        if not self.product_id:
            return {'domain': {'product_uom': []}}

        vals = {}
        domain = {'product_uom': [('category_id', '=', self.product_id.uom_id.category_id.id)]}
        if not self.product_uom or (self.product_id.uom_id.category_id.id != self.product_uom.category_id.id):
            vals['product_uom'] = self.product_id.uom_id

        product = self.product_id.with_context(
            lang=self.order_id.partner_id.lang,
            partner=self.order_id.partner_id.id,
            quantity=self.product_uom_qty,
            date=self.order_id.date_order,
            pricelist=self.order_id.pricelist_id.id,
            uom=self.product_uom.id
        )

        name = product.name
        if product.description_sale:
            name += '\n' + product.description_sale
        vals['name'] = name

        self._compute_tax_id()

        if self.order_id.pricelist_id and self.order_id.partner_id:
            vals['price_unit'] = self.env['account.tax']._fix_tax_included_price(product.price, product.taxes_id, self.tax_id)
        self.update(vals)
        return {'domain': domain}

Did you want to remove the internal reference shown in individual product descriptions?  If so it is the "Internal Reference" box shown below.  Highlight text > Delete > Save.

If you want to remove the actual field then sorry, I dont know.

Dear Chirag,

Yes, @Serpent Consulting Services is right you need to override the name_get method like this 

class product_product(osv.Model):

        _inherit = 'product.product'

        def name_get(self, cr, uid, ids, context={}):

            res = []

            if context is None:

                context = {}

            if isinstance(ids, (int, long)):

                ids = [ids]

            if not len(ids):

                return []

            for product in self.browse(cr, uid, ids,context=context):

                res.append((product.id, product.name))

            return res

Hope this code may be help full

How do I go about doing that?
