А такой вариант ?

    qbdsInventTrans.addRange(fieldNum(InventTrans, DateFinancial)).value(strfmt('(((%1.%2 + %3.%4 - %5) > 0))',
                                                                                 query.dataSourceTable(tableNum(InventTrans)).name(),
                                                                                 fieldStr(InventTrans, DateFinancial),
                                                                                 query.dataSourceTable(tableNum(Table2)).name(),
                                                                                 fieldStr(Table2, Days),
                                                                                 date2StrXpp(systemDateGet()));
