> When there are two lookup table using same name in one cube, the cube engine will raise exception since it do not know which column coming from which table.
> Using full qualified name with _database.tablename.columnname_ to unique identify column in row key.
> Workaround: duplicate lookup table with specified name and join with fact.
> For example: duplicate dw_countries to dw_countries_seller and dw_countries_buyer.
