[AX2009] Merge Query Range from Two Different Queries

In my case, I want to merge query ranges from Query object to Form Data source. The data source will join to CustTable. The CustTable will be filtered by Query Object TIDCustTable.

public class FormRun extends ObjectRun
{
    QueryBuildDatasource    qbds3;
    Query                   q3;
    QueryRun                qRunCustTable;
}

 public void init()
{
    QueryBuildDatasource    qbds1, qbds4;
    ;
    qRunCustTable = new QueryRun(QueryStr(TIDCustTable));
    super();
    qbds1 = TIDIRTable_ds.query().dataSourceTable(tablenum(TIDIRTable));
    qbds4 = SalesTableDS_ds.query().dataSourceTable(tablenum(SalesTable));
    qbds4.addLink(fieldnum(TIDIRTable, SalesId), fieldnum(SalesTable, SalesId));

    qbds3 = qbds1.addDataSource(tablenum(CustTable));
    qbds3.addLink(fieldnum(TIDIRTable, InvoiceAccount), fieldnum(CustTable, AccountNum));
}

When click Select button:

void btnSelect()
{
    ;
    if(qRunCustTable.prompt())
    {
        q3  = new Query(qRunCustTable.query());
    }
}

Process button:

public void btnProcess()
{
    QueryBuildDatasource    qbds1 = TIDIRTable_ds.query().dataSourceTable(tablenum(TIDIRTable));
    QueryBuildDatasource    qbds4 = SalesTableDS_ds.query().dataSourceTable(tablenum(SalesTable));
    ;

    if(element.validateProcess())
    {
        qbds3.clearRanges();
        if(qRunCustTable.query().dataSourceTable(tablenum(CustTable)).rangeCount() >0)
            element.mergeRanges(TIDIRTable_ds.query(), qRunCustTable.query(), 4);//4 is table number of CustTable in TIDIRTable query

        SysQuery::findOrCreateRange(qbds1, fieldnum(TIDIRTable, InvoiceDate)).value(SysQuery::range(dtFromDate.dateValue(), dtToDate.dateValue()));
        if(txBranch.valueStr())
        {
            SysQuery::findOrCreateRange(qbds1, fieldnum(TIDIRTable, CountryRegionId)).value(SysQuery::value(txCountryRegionId.valueStr()));
            SysQuery::findOrCreateRange(qbds1, fieldnum(TIDIRTable, Branch)).value(SysQuery::value(txBranch.valueStr()));
        }
        else
        {
            if(qbds1.findRange(fieldnum(TIDIRTable, CountryRegionId)))
                qbds1.clearRange(fieldnum(TIDIRTable, CountryRegionId));

            if(qbds1.findRange(fieldnum(TIDIRTable, Branch)))
                qbds1.clearRange(fieldnum(TIDIRTable, Branch));
        }

        if(cbSalesStatus.selection() == SalesStatus::None)
        {
            qbds4.joinMode(JoinMode::OuterJoin);
            if(qbds4.findRange(fieldnum(SalesTable, SalesStatus)))
            {
                qbds4.clearRange(fieldnum(SalesTable, SalesStatus));
            }
        }
        else
        {
            qbds4.joinMode(JoinMode::InnerJoin);
            SysQuery::findOrCreateRange(qbds4, fieldnum(SalesTable, SalesStatus)).value(SysQuery::value(cbSalesStatus.selection()));
        }
        TIDIRTable_ds.executeQuery();
    }
}
