## MDX Operators: The IsLeaf() Operator: Conditional Logic within Calculations - Page 3October 2, 2006
Let’s assume, for purposes of our practice example, that we
have received a request for assistance from representatives of our client, the The analysts tell us that the averages under immediate
consideration involve Our client colleagues inform us that they initially need to
understand a means, within MDX, of distinguishing After we introduce the concepts behind the
Per the request of our client colleagues, we will first construct
a simple query to provide an illustration of the use of the 1.
