{
    Set<String> cmpnyName = new Set<String>();
    Set<String> ledName = new Set<String>();

    map<string,Id> cmpnyAccMap = new map<string,Id>();
    map<string,Id> leadConMap = new map<string,Id>();
    for(lead cf:trigger.new)
    {
        cmpnyName.add(cf.Company);
        ledName.add(cf.Name);
    }

    for(Account acc: [Select Id,Name  from Account Where Name IN: cmpnyName])
        cmpnyAccMap.put(acc.name, Acc.id);
    for(contact con: [Select Id,LastName  from contact Where LastName IN: ledName])
        leadConMap.put(con.LastName,con.id);

    for(lead cf:trigger.new)
    {

        lead cd= new lead(id=cf.id);

        Database.LeadConvert lc = new database.LeadConvert();
        lc.setLeadId(cd.id);
         lc.ConvertedStatus ='Closed - Converted';
        if(cmpnyAccMap.containsKey(cf.Company))
            lc.setAccountId(cmpnyAccMap.get(cf.Company));
        if(leadConMap.containsKey(cf.Name))
            lc.setContactId(leadConMap.get(cf.Name));
        lc.setDoNotCreateOpportunity(true);

        Database.LeadConvertResult lcr = Database.convertLead(lc);
        System.assert(lcr.isSuccess());

    }
}

I am not getting the any error,Lead is Converting,account is Pointing in the Existing Account ,Contact is Not Pointing existing Contact

Please Anyone Guide Me for the Answer

Answer 1

In your Lead Name Set, you are adding the full name of the Lead record

ledName.add(cf.Name);

and when you are querying Contacts, you are checking it against the last name

Select Id,LastName from contact Where LastName IN: ledName

you can change your query to match the full name of the contact against the full name of the lead.. then you should see the lead mapping to existing contact if the name matches..

Select Id,LastName from contact Where Name IN: ledName
