SSRS and MDX: Think about Cell Properties
I stumbled across a small MDX performance tuning trick when using SSRS reports (or any other client tool where you can edit the MDX). When you create the MDX query using the designer, it will append some cell properties at the end of the query. Basically it’s just metadata about the cells of the result […]

In other words, the […]

Nested Display Folders in SSAS
Recently it was announced that Power BI would now support the SSAS display folders in “exploration mode”. Exploration mode is a fancy term for a live connection to an SSAS cube or model. Anyway, great news, as it drastically improved usability of Power BI Desktop when browsing cubes. On the same day, I also found […]
