An alternative Time Intelligence implementation. Year-To-Date and Difference-Over-Previos-Year (or Year-Over-Year Growth) are among the most required features of any user. Some OLAP client (like ProClarity) offers features that try to solve this problem client-side, but I don’t like this approach given that you might have a server-side feature doing that (so you don’t discriminate Excel users). One trivial approach is creating a calculated measure for each combination of measure and date-calculation. While this works, it results in a multiplication of the number of measures, making the cube hard to use. Analysis Services offers a feature called Time Intelligence Wizard that creates some calculated members on dedicated Date attributes. This works in MDX but has several limitations...
