You can only do this through a module - python code that defines the three custom fields on sale.order, stock.picking and account.invoice.

Have a look at http://v6apps.openerp.com/addon/6739

1) It adds a new custom field address_shipping_id to account.invoice

2) It overrides the _make_invoice function in sale.order to populate the shipping address by copying it over from the Sales Order.

Hi, Ray thanks for your answer. I followed your advice I think I understand in part. I generate this code but send me an error, maybe you can help me with this:

class account_invoice(osv.osv):

_inherit = 'account.invoice'
_name = 'account.invoice'


_columns = {
        'origen_pos_id': fields.many2one('pos.order', 'Relación Ticket', required=False),
        'origen_invoice_id': fields.many2one('account.invoice', 'Relación Factura', required=False),
        }

account_invoice()

class purchase_order(osv.osv):

_inherit = 'purchase.order'
#_name = 'purchase.order'


_columns = {
        'ref_oc': fields.char('Referencia OC', size=64, readonly=False),
        'ref_pos_id': fields.many2one('pos.order', 'Relación Ticket', required=False),
        'ref_invoice_id': fields.many2one('account.invoice', 'Relación Factura', required=False),
        }


def action_invoice_create(self, cr, uid, ids, context=None):
    """
    Extended
    """
    #  create invoice
    invoice_id = super(purchase_order, self).action_invoice_create(cr, uid, ids, context=context)

    # check

    vals = {}
    for order in self.brows(cr, uid, ids):
      if order.ref_pos_id:
        vals['origin_pos_id'] = order.ref_pos_id.id
      if order.ref_invoice_id:  
        vals['origin_invoice_id'] = order.ref_invoice_id.id

        if vals:
            # write to invoice
            self.pool.get('account.invoice').write(cr,uid, [invoice_id], vals)
            return invoice_id

purchase_order()
