parameters fields performance with complex DAX

[Leonardiho8]

Hi

I probe the new power bi function "Parameters fields" and I have a problem with the performance. 

My measure is a complex DAX but when I have a Matrix with dimension "Parameters fields" is slower with add one to one dimension what makes it up

How affect the "Parameters fields" that performance?

Hi @Leonardiho8 ,

As far as I know, we will use SELECTEDVALUE() to catch single value and use VALUES() to catch a list of values. We will use equal( = ) to compare with single value and use in to compare with list of values in dax code.

I think Power BI performance will be affected by many conditions like data model, size of underlying data, complexity of the query.

You may refer to this offical blog to learn more details about how to optimization Power BI Performance.
