    Thanks Amit.

            This is my xml for report(inside calldetails/report/calldata_report.xml)
            <?xml version="1.0"?>
            <openerp>
                    <data>
                            <report
                                    id="report_calldata"
                                    string="call details"
                                    model="calldata"
                                    name="report.calldata_report"
                                    rml="calldetails/report/calldata_report.rml"
                                    auto="False"/>
                    </data>
        </openerp>

    My model is (inside calldetails/calldata.py)
        from osv import osv,fields
          class calldata(osv.osv):
            _name = 'calldata'
            _columns = {
              'Call_start': fields.datetime('Call start'),
              'Call_duration':fields.datetime('Call duration'),
              'Ring_duration':fields.float('Ring duration'),
              'Caller':fields.char('Caller'),
              'Direction':fields.char('Direction'),
              'Called_number':fields.char('Called number'),
              'Dialled_number':fields.char('Dialled number'),
              'Account':fields.char('Account'),
              'Is_Internal':fields.boolean('Is internal'),
              'Call_ID':fields.char('Call id'),
              'Continuation':fields.boolean('Continuation'),
              'Party1Device':fields.char('Party1device'),
              'Party1Name':fields.char('Party1name'),
              'Party2Device':fields.char('Party2device'),
              'Party2Name':fields.char('Party2name'),
              'Hold_Time':fields.float('Hold time'),
              'Park_Time':fields.float('Park time'),
           }
        calldata()

    My report object creation code is (inside calldetails/report/calldata_report.py)
        from report import report_sxw
        from osv import  osv
        class test_parser(report_sxw.rml_parse):
         def __init__(self,cr,uid,name,context):
           super(test_parser, self).__init_(cr,uid,name,context=context)
           self.localcontext.update({})
        report_sxw.report_sxw('report.calldata_report',
                               'calldata',
                                'addons/calldetails/report/calldata_report.rml',
                                parser=test_parser )
 And inside record folder i added  __init__.py (i imported calldata_report.py) and calldata_report.rml file( contains code copied from sale/report/sale/ sale_order.rml)        
 and in (calldetails/__.openerp__.py) i added
 {"name" : "SMDR",
        "version" : "1.0",
        "author" : "Anuradha",
        "category" : "Generic Modules",
        "description": "call details",
        "website":"added website here but i cant post it due to insuffient karma",
        "depends" : ["base"],
        "init_xml" : [],
        "update_xml" : ["initial.xml","calldata_display.xml","report/calldata_report.xml"],
    #    "data":["calldata_report.xml"],
        "installable": True,
        "active": False
    }
    and added report module in calldetails/__init__.py also .

    Please help me to find issue i have been working on it for a long time

Hello,

menu="True" not required parameter any more. But I think you might have mistake on model name. model is object name where you want to show this report like if you create report for res.partner object then model name must be 'res.partner'.

Under the name parameter you have to pass the report object name, for example if my report object is report.amp.test then name would be amp.test.

Thank you!
