Есть такой запрос:

public void init()
{
    queryBuildDataSource    queryBuildDataSource;
   ;

    super();
    rassetTransDate  = this.args().caller().rassetTransDate();
    rassetStandardId = this.args().caller().assetStandard();
    zeroBookValue    = this.args().caller().zeroBookValue();

    queryBuildDataSource = this.query().dataSourceName("RAssetTable").addDataSource(tableNum(RAssetStandards));
    queryBuildDataSource.fetchMode(JoinMode::EXISTSJOIN);

    queryBuildDataSource.relations(false);
    queryBuildDataSource.addLink(fieldnum(RAssetTable, accountNum), fieldnum(RAssetStandards, assetId));
    queryBuildDataSource.addRange(fieldnum(RAssetStandards, assetStandardId)).value(queryValue(rassetStandardId));

    queryBuildDataSource.addSelectionField(fieldnum(RAssetTable, ROP_AbacusNum_3), SelectionField::Min);

    rassetSumTrans = RAssetSumCalc_Trans::newAssetPeriod((select firstonly RAssetTable).AccountNum, rassetStandardId, rassetTransDate);
}

Как сделать группировку по какому-то полю в таблице "RAssetTable"?

Помогите плз, целый день мучаюсь.
