Dear Friends,

I have a mapping of Cluster and LOCs and want to display LOCs in a PBI Matrix object for the Cluster selected in slicer

Cluster1   LOC1

Cluster1   LOC2

Cluster1   LOC3

Cluster1   LOC4

Cluster2   LOC1

Cluster2   LOC2

Cluster3   LOC3

Cluster3   LOC4

My requirement is if no Cluster is filtered in slicer then it should show the list of LOCs for "Cluster1" only
