Если есть возможность загляните в AX 2012 R3, может быть там не только эти баги исправлены, вот как выглядят данные выборки в InventCostItemDim

countryRegion_RU = SysCountryRegionCode::isLegalEntityInCountryRegion([#isoRU]);

В DAX2009 насколько я помню регион как то по другому определяется, но смысл думаю ясен.
