MDX Order Function

Order MDX function is used to show the result set in specified order. Generally we set OrderBy property of key attribute as Key. Sometime we want to define the customized order wherein we can create another attribute on different column which store Order like 1,2,3.....and then we can set OrderBy property of KeyAttribute as "AttributeKey" and specify the attribute name (which stores customized ordering) under "OrderByAttribute" property.
