Your right, i understood it.. Hmm by the way try to do this.. in your .py inherit the crm.phonecall class and put the field contact name

class crm_phonecall(osv.osv): 
_inherit = "crm.phonecall"
_columns = {
   'contact_name': fields.char('Contact Name', size=64),        
    }
 crm_phonecall()

and in your .xml add the contact_name field

   <record id="call_contact_name" model="ir.ui.view">
        <field name="name">call.contact.name</field>
        <field name="model">crm.phonecall</field>
        <field name="type">form</field>
        <field name="priority">10</field>
        <field name="inherit_id" ref="crm.crm_case_phone_form_view"/>
          <field name="arch" type="xml">

               <xpath expr ="//field[@name='date']" position="before">
                    <field name="contact_name"/>
              </xpath> 

          </field>
    </record>

Inherit the crm.lead class and get its "schedule_phonecall" method which is responsible 4 transferring tha data from lead to schedule calls.. Add the contact_name inside the "VALS"

class crm_lead(osv.osv): 
_inherit = "crm.lead"
def schedule_phonecall(self, cr, uid, ids, schedule_time, call_summary, desc, phone, contact_name, user_id=False, section_id=False, categ_id=False, action='schedule', context=None):
    """
    :param string action: ('schedule','Schedule a call'), ('log','Log a call')
    """
    phonecall = self.pool.get('crm.phonecall')
    model_data = self.pool.get('ir.model.data')
    phonecall_dict = {}
    if not categ_id:
        res_id = model_data._get_id(cr, uid, 'crm', 'categ_phone2')
        if res_id:
            categ_id = model_data.browse(cr, uid, res_id, context=context).res_id
    for lead in self.browse(cr, uid, ids, context=context):
        if not section_id:
            section_id = lead.section_id and lead.section_id.id or False
        if not user_id:
            user_id = lead.user_id and lead.user_id.id or False
        vals = {
            'name': call_summary,
            'opportunity_id': lead.id,
            'user_id': user_id or False,
            'categ_id': categ_id or False,
            'description': desc or '',
            'date': schedule_time,
            'section_id': section_id or False,
            'partner_id': lead.partner_id and lead.partner_id.id or False,
            'partner_phone': phone or lead.phone or (lead.partner_id and lead.partner_id.phone or False),
            'partner_mobile': lead.partner_id and lead.partner_id.mobile or False,
            'priority': lead.priority,
            'contact_name':lead.contact_name
        }
        new_id = phonecall.create(cr, uid, vals, context=context)
        phonecall.case_open(cr, uid, [new_id], context=context)
        if action == 'log':
            phonecall.case_close(cr, uid, [new_id], context=context)
        phonecall_dict[lead.id] = new_id
        self.schedule_phonecall_send_note(cr, uid, [lead.id], new_id, action, context=context)
    return phonecall_dict

_columns = {
   'contact_name': fields.char('Contact Name', size=64),
  }
 crm_lead()

Although the contact_name will not appear in this window

but in your schedule log calls menu.. it will appear, if you put contact_name in your lead form

A lead in OpenERP is a source of information that someone in your company needs to qualify before deciding if anyone should spend time and energy following up.

It could be a name from a list you bought, a business card from a tradeshow, an incoming email to your website, an email from a registration page, a message that a caller left, etc.

The out of the box workflow (ie: without customization) that the software supports is to convert a lead into an opportunity if call needs to be scheduled - then the contact information (person & company) will show up as you expect.

I understand what you want to do, and it is certainly is possible with customization, but this is my advice - convert the lead into an opportunity if you think it is worth a scheduled call.

Leave it a lead until someone spends time deciding if it is worth anyone's time following up. If you know enough to know when a return call should be scheduled (if someone has asked you to call back), you probably know enough to justify converting it into an opportunity.

Hi lhadiesleo,

Thanks for your help.

I open crm_phonecall.py and edit it as below (follow your screen shot no 1) but I got this error. "TypeError: The model "crm.phonecall" specifies an unexisting parent class "crm.phonecall". You may need to add a dependency on the parent class' module." I am newbie in python language. May I know how to solve this problem? Many thanks.

class crm_phonecall(base_state, osv.osv): """ Model for CRM phonecalls """ _name = "crm.phonecall" _description = "Phonecall" _order = "id desc" _inherit = ['mail.thread','crm.phonecall'] _columns = { # base_state required fields 'contact_name': fields.char('Contact Name', size=64), 'date_action_last': fields.datetime('Last Action', readonly=1), ...
