#### Examples

This example returns the rank of each promotional item in the list of promotions.

The simple rank (second measure in the grid below), using nothing but the promotion item, ranks it in the natural order of the elements of the hierarchy. Note the use of "currentmember" to select the current promotion per cell in the grid.

Rank( [promotions].[Promotion].CurrentMember. {AllMembers([promotions].[Promotion])} )

The numeric rank (third measure in the grid below), using but the promotion item's sales value and ranks it in the order of the other promotional element sales. So Half-Price pedal sale is still ranked "1" - since it has the lowest sales in the list, while "No Discount" is ranked 15th, since it is the second highest sales value in the list.

Rank( [promotions].[Promotion].CurrentMember. {AllMembers([promotions].[Promotion])}, ([measures].[data Sales]) )
