Adding QueryRange to datasource table

Dears,

Hope every one doing well,

I want to retrieve all the active positions from e.g PositionTable, and add some ranges to it, in this table every position is linked to an organization.

I want to retrieve all positions with other organizations but only specified employee's from organization (10) for example those employees whose positongroup is (aboveManger) will come from the organization (10) but from other organizations rest of them. how should I do it?

Here is my code:

    Query                                        query;

    PositionId                                positionId;

    QueryBuildDataSource        qbds1,qbds2;

    ;

    query=new query();

    qbds1 = query.addDataSource(tablenum(PositionTable));

    qbds2 = qbds1.addDataSource(tableNum(PositionTable));

    qbds2.relations(false);

    qbds2.joinMode(JoinMode::ExistsJoin);

   qbds2.addLink(fieldnum(PositionTable,PositionId),fieldnum(PositionTable,ReportsToPosition));

   qbds1.addRange(fieldnum(PositionTable,ValidFromDateTime)).value(QueryRange(DateNull(),SystemDateGet()));

   qbds1.addRange(fieldnum(PositionTable,ValidToDateTime)).value(QueryRange(SystemDateGet(),DateNull()));

   qbds2.addRange(fieldnum(PositionTable,ValidFromDateTime)).value(QueryRange(DateNull(),SystemDateGet()));

   qbds2.addRange(fieldnum(PositionTable,ValidToDateTime)).value(QueryRange(SystemDateGet(),DateNull()));

Thanks in advance!
