i have code like this

def _picking_assign(self,cr, uid, move_ids, procurement_group, location_from, location_to, context=None):
pick_obj = self.pool.get("stock.picking")
    move = self.browse(cr,uid,move_ids[0])
    obj_model = self.pool.get('ir.model')
    obj_model_id = obj_model.search(cr,uid,[ ('model','=',move.procurement_id.sale_line_id.order_id.__class__.__name__) ])
    if move.cabang:
    values = {
            'origin': move.origin,
            'company_id': move.company_id and move.company_id.id or False,
            'move_type': move.group_id and move.group_id.move_type or 'direct',
            'partner_id': move.partner_id.id or False,
            'picking_type_id': move.picking_type_id and move.picking_type_id.id or False,
            'group_id': procurement_group,
            'location_dest_id': location_to,
            'cabang': move.cabang.id,
            'state': 'draft',
            'transaction_id': move.procurement_id.sale_line_id.order_id.id,
            'model_id': obj_model_id[0]
        pick = pick_obj.create(cr, uid, values, context=context)
        self.write(cr, uid, move_ids, {'picking_id': pick}, context=context)
    res = super(stock,self)._picking_assign(cr, uid, move_ids, procurement_group, location_from, location_to, context=context)
    return res

but i getting error like this

File "/home/susi/odoo/addons/SAVIRA/mcs_sale_order/mcs_procurement_order.py", line 28, in_picking_assign    pick_obj.force_assign(cr,uid,pick)ValueError: "local variable 'pick' referenced before assignment" while evaluatingu'action_ship_create()'

dear Susi

you need to define pick=False variable out of if statement.

and you must check it before call it as parameter on pick_obj.force_assign(cr,uid,pick)

like this

if pick:

I hope I helped you...

dear ayman, thanks before for your answer. i have try your solution its not getting error again. but the value field that i want get its still empty. do you know why?

Hai Susi,.
  You assigned pick variable "pick = pick_obj.create(cr, uid, values, context=context)"  inside a if block in this function[ if move.cabang:]. In case this if condition fails, the pick will not assign. It will arise error message while you use pick variable in any other function or block. So you have to set a dummy value to pick outside of if block

Hello Susi,

Local variable is accessible within a block only.

Here you have declare pick variable that is storing the result return by a create method.

that pick variable is accessible within a if block only.

if you need to access it then you must declare the same variable outside of block.

I Hope this will help you.
