adding a DynaLink through code

example:

public void init() //on form datasource reqPO
{
    QueryBuildDatasource    QBDSReqPO;
    ;

    super();

    QBDSreqPO = this.query().dataSourceTable(tablenum(reqPO));
    QBDSreqPO.clearDynalinks();
    QBDSreqPO.addDynalink( fieldnum(reqPO,ADUcollectrefid), ADUQRMWipTable, fieldnum(ADUQRMWipTable,refid));
    QBDSreqPO.addRange(fieldnum(reqpo,reqplanid)).value(reqparameters::find().CurrentReqPlanIdSchedStatic);
}
