Hi darius, Now I'm working with new module inherit to res.partner. Create simple workflow and add state field. Do you have example how to push internal note when user click the button? from openerp import models, fields, api, tools from openerp.tools.translate import _ class res_partner(models.Model): _inherit = 'res.partner' STATE_SELECTION = [ ('draft', 'Request Approval'), ('approved', 'Approved'), ] state = fields.Selection(STATE_SELECTION, 'Status', readonly=True, help="Request Approval Record " "Approved Record. ", select=True,default='draft') @api.multi def write(self, vals): if self.state == 'approved': vals.update({'state':'draft'}) # add internal note comment return super(res_partner, self).write(vals) @api.multi def button_approved(self, vans): # add internal note comment self.write({'state': 'approved'})
