Hi friendz,

I am facing a problem in which my added field in project needs to be removed. When I deleted the field, restarted the server and upgraded the module, the field deleted was still available in my local server.

class account_voucher(osv.osv):
    _inherit = 'account.voucher'
    _columns = {
        'transId': fields.char('Transaction ID', size=128, readonly=True, help="The transaction ID returned by Authorize.net.  Used for voiding a transaction."),
        'error_text': fields.char('Authorization Status', size=128, readonly=True, help="The transaction error details reported by Authorize.net. Left blank if the transaction was successful."),
        'is_approved': fields.boolean('Approved', readonly=True),
        'state': fields.selection(
            [('draft','Draft'),
            ('dispute','Error'),
            ('cancel','Cancelled'),
            ('proforma','Pro-forma'),
            ('posted','Posted'),
            ], 'Status', readonly=True, size=32, track_visibility='onchange',),
        'cim_id': fields.many2one('account.authnet.cim', 'Customer Profile', domain="[('partner_id','=',partner_id)]"),
        'cim_payment_id': fields.many2one('account.authnet.cim.payprofile', 'Card on File', domain="[('cim_id','=',cim_id)]"),
        'card_type': fields.char('Card Type', size=16, help="The type of card used to pay.  Visa, MasterCard, American Express, etc."),
        'transaction_ids': fields.one2many('credit.card.transaction','payment_id', string='CC Transaction', readonly=True),
    }

class account_voucher(osv.osv):
    _inherit = 'account.voucher'
    _columns = {
        'is_approved': fields.boolean('Approved', readonly=True),
        'state': fields.selection(
            [('draft','Draft'),
            ('dispute','Error'),
            ('cancel','Cancelled'),
            ('proforma','Pro-forma'),
            ('posted','Posted'),
            ], 'Status', readonly=True, size=32, track_visibility='onchange',),
        'cim_id': fields.many2one('account.authnet.cim', 'Customer Profile', domain="[('partner_id','=',partner_id)]"),
        'cim_payment_id': fields.many2one('account.authnet.cim.payprofile', 'Card on File', domain="[('cim_id','=',cim_id)]"),
        'transaction_ids': fields.one2many('credit.card.transaction','payment_id', string='CC Transaction', readonly=True),
    }

Is there any procedure to do for removing field added by inheriting.? fields deleted -transId, error_text, card_type

Thanks
