Lookup on PersonnelNumber and Name in Ax2012

In Ax2009 EmplTable now replaced with hcmWorker Table. To get emplid and emplname below is the lookup code:
public void lookup()
{
    HcmWorker               hcmWorker;
    SysTableLookup          sysTableLookup = SysTableLookup::newParameters(hcmWorker.TableId, this);
    Query                   query = new Query();
    QueryBuildDataSource    queryBuildDataSource = query.addDataSource(hcmWorker.TableId);

    queryBuildDataSource.addSortField(fieldNum(HcmWorker, PersonnelNumber));

    sysTableLookup.addLookupfield(fieldNum(HcmWorker, PersonnelNumber));
    sysTableLookup.addLookupfield(fieldNum(HcmWorker, Person));

    sysTableLookup.parmQuery(query);
    sysTableLookup.performFormLookup();
}
