This post shows how you can generate optimized multi-value DAX parameters in SSRS and achieve greater performance compared to the DAX PathContains function.

I’m assuming the reader has experience with SSRS, so not all steps will be shown. Imagine that you have multi-value parameter that allows users to select multiple month – year values such as Sep 2017, Oct 2017, etc. TheRead More →

If your labels always contain the same number of characters, you can use the MID function as shown later. I have multiple multi-value parameters being passed, however, so I wanted to be able toRead More →
