AX 2009 Ошибка запроса с условием по полю Dimension[x]

[ziva]

Возможно здесь где-то уже пролетала такая ошибка ...
К сожалению, результат выполнения двух этих циклов разный.
Первый выдает инфолог, второй - нет.
Отличаются только указанием условия inventTable.Dimension[12]:

    VendInvoiceTrans    vendInvoiceTrans;
    InventTable         inventTable;
    ;

    while select forceliterals vendinvoiceTrans
        group by TableId
        where vendinvoiceTrans.Voucher == "Ю3РПН00710274"
    join inventTable
        group by Dimension[12]
        where inventTable.ItemId == vendinvoiceTrans.ItemId
           && inventTable.Dimension[12] != ''
    {
        info("1 - OK");
    }

    while select forceliterals vendinvoiceTrans
        group by TableId
        where vendinvoiceTrans.Voucher == "Ю3РПН00710274"
    join inventTable
        group by Dimension[12]
        where inventTable.ItemId == vendinvoiceTrans.ItemId
           && inventTable.Dimension[12]
    {
        info("2 - OK");
    }

А запросы на БД идут вот такие интересные.

В первом цикле - вполне корректный:

SELECT B.DIMENSION12_ FROM VENDINVOICETRANS A,INVENTTABLE B WHERE ((A.DATAAREAID=N'y31i') AND (A.VOUCHER=N'Ю3РПН00710274')) AND ((B.DATAAREAID=N'y31i') AND ((B.ITEMID=A.ITEMID) AND (B.DIMENSION12_<>' '))) GROUP BY B.DIMENSION12_ ORDER BY B.DIMENSION12_

А во втором - WTF?!

SELECT B.DIMENSION12_ FROM VENDINVOICETRANS A,INVENTTABLE B WHERE ((A.DATAAREAID=N'y31i') AND (A.VOUCHER=N'Ю3РПН00710274')) AND ((B.DATAAREAID=N'y31i') AND ((B.ITEMID=A.ITEMID) AND ((((((((((((((((((B.DIMENSION>' ') AND (B.DIMENSION2_>' ')) AND (B.DIMENSION3_>' ')) AND (B.DIMENSION4_>' ')) AND (B.DIMENSION5_>' ')) AND (B.DIMENSION6_>' ')) AND (B.DIMENSION7_>' ')) AND (B.DIMENSION8_>' ')) AND (B.DIMENSION9_>' ')) AND (B.DIMENSION10_>' ')) AND (B.DIMENSION11_>' ')) AND (B.DIMENSION12_>' ')) AND (B.DIMENSION13_>' ')) AND (B.DIMENSION14_>' ')) AND (B.DIMENSION15_>' ')) AND (B.DIMENSION16_>' ')) AND (B.DIMENSION17_>' ')) AND (B.DIMENSION18_>' ')))) GROUP BY B.DIMENSION12_ ORDER BY B.DIMENSION12_
