Cannot use measure in slicer

Hello Chris741,

A measure can't be used in clicer directly. You can try this.

1. Create a table named "ForSlicer" like this (sign 1 in the pic).

Pareto_SalesUnits_Name    SlicerValue
Slow Mover                           0
Fast Mover                            1

2. Create a measure as below. Maybe you need to make some change.
Pareto_SalesUnits_Name =
IF (
    HASONEVALUE ( 'ForSlicer'[Pareto_SalesUnits_Name] ),
    IF (
        VALUES ( 'ForSlicer'[SlicerValue] ) = 1,
        IF([SalesUnits_CumPerc]>[Pareto_BM],BLANK(),"Fast mover"),
        IF([SalesUnits_CumPerc]>[Pareto_BM],"Slow mover",BLANK())
    ),
    IF([SalesUnits_CumPerc]>[Pareto_BM],"Slow mover","Fast mover")
)

3. Create a clicer using column "Pareto_SalesUnits_Name" in table FORSLICER (sign 2 in the pic).

4. Set the visual level filter of the measure "Pareto_SalesUnits_Name" to "is not blank". (sign 3 in the pic).

5. It works though it's not perfect. Hope this would be a little help.
