Hi Anoop ,


Let me try 

1. I create a new folder = 'purchase_discount'
2. I create 2 new py , __init__.py and __terp__.py
    where __init__.py have 1 line

> import purchase_discount


   __terp__.py  code are as follow


from osv import fields
from osv import osv
import time
import netsvc

import ir
from mx import DateTime
import pooler
from tools import config

class purchase_order_line(osv.osv):
    _name = 'purchase.order.line'
    _inherit = 'purchase.order.line'
    _columns = {
        'discount': fields.float('Discount 
(%)', digits=(16,2)),
    }
purchase_order_line() 


and a python code , purchase_discount.py

from osv import fields
from osv import osv
import time
import netsvc

import ir
from mx import DateTime
import pooler
from tools import config

class purchase_order_line(osv.osv):
    _name = 'purchase.order.line'
    _inherit = 'purchase.order.line'
    _columns = {
        'discount': fields.float('Discount 
(%)', digits=(16,2)),
    }
purchase_order_line()
