The daily Axapta WTF

Вчера наткнулся в методе Classes\InventAdjustPost\updateTotal на очень удививший меня код.

protected  void updateTotal()
{
    InventSettlement        inventSettlement;
    InventTrans             inventTrans;
    ProjLedger              projLedger;

    while select forcePlaceHolders forceSelectOrder sum(costAmountadjustment) from inventSettlement
        index hint DateVoucherIdx
        group by itemId,balanceSheetPosting,balanceSheetAccount,operationsPosting,operationsAccount,dimension
        where inventSettlement.transDate              == transDate    &&
              inventSettlement.voucher                == voucher      &&
              inventSettlement.costAmountAdjustment   != 0            &&
              inventSettlement.InventTransCurrency_RU == inventTransCurrency &&
              inventSettlement.posted                 == NoYes::No
    join inventTrans
        index hint recId
        group projId,projAdjustRefId,inventTransId
        where inventTrans.RecId == inventSettlement.TransRecId
    {
        if (correspondenceEnable)
        {
            this.updateMap_RU(inventSettlement,inventTrans);
        }
        else
        {
            projLedger = this.newProjLedger_RU(inventTrans.ProjId,
                                               inventTrans.InventTransId,
                                               inventTrans.ProjAdjustRefId);
            this.updateTrans(inventSettlement, ledgerVoucher,projLedger);
        }
    }
    this.updateTrans_RU();
}

Обратите внимание на группировку в join запросе по inventTrans - там используется group, но нету by

Это вообще нормально??
