Limit slicer based on multiple slicers

[Anonymous]

Hi,

I've built 4 identical slicers each with different types of cancer a person can have across their lifetime. The full list has 10 cancer types and would like subsequent slicers to only have the option to select those not already chosen from previous slicers. At the moment I can incorrectly select the same cancers across all 4 slicers. can you assist?

For the slicers to be mutually exclusive, you need to create a measures to use in each slicer as a filter in the filter pane, following this (CT Slicer * is the name of each table used as slicers):

Filter 1 = 
VAR S1 = 'CT Slicer 1'
VAR S2 = 'CT Slicer 2'
VAR S3 = 'CT Slicer 3'
VAR S4 = 'CT Slicer 4'
VAR SelectedCT = 
DISTINCT(
    UNION(S2, S3, S4))
    RETURN
COUNTROWS(
    EXCEPT(S1,SelectedCT))

Filter 2 = 
VAR S1 = 'CT Slicer 1'
VAR S2 = 'CT Slicer 2'
VAR S3 = 'CT Slicer 3'
VAR S4 = 'CT Slicer 4'
VAR SelectedCT = 
DISTINCT(
    UNION(S1, S3, S4))
    RETURN
COUNTROWS(
    EXCEPT(S2, SelectedCT))

Filter 3 = 
VAR S1 = 'CT Slicer 1'
VAR S2 = 'CT Slicer 2'
VAR S3 = 'CT Slicer 3'
VAR S4 = 'CT Slicer 4'
VAR SelectedCT = 
DISTINCT(
    UNION(S1,S2,S4))
    RETURN
COUNTROWS(
    EXCEPT(S3,SelectedCT))

Filter 4 = 
VAR S1 = 'CT Slicer 1'
VAR S2 = 'CT Slicer 2'
VAR S3 = 'CT Slicer 3'
VAR S4 = 'CT Slicer 4'
VAR SelectedCT = 
DISTINCT(
    UNION(S1,S2,S3))
    RETURN
COUNTROWS(
    EXCEPT(S4,SelectedCT))

Now add each measure to the filter pane for each corresponding slicer. Before you set the filter, select a  different value for each slicer

Then set the value of each measure  in each filter to = 1.

This is brilliant. Just bedded this into my dashboard and works a treat. Many thanks Paul.
