There is something odd with an ArcGIS in the way it treats measures and the format associated with them.
I have a map that works great but when I however hover over my map the counts associated with it all have 2 decimal place formatting even though they are formated for 0 decimal place. the associatyed matrix is formatted okay.
The odd thing is the measures are also formatted with a comma (,) for 000's. If I remove this this formatting then I lose the decimal places BUT I lose the comma in my matrix. Bizarrely I will keep the comma formatting on the map?
You can work around but you have to create another measure based on the first measure but with different formatting.
I can reproduce your issue, it seems the measure decimal place feature not works on arcgis map. I will report this to power bi team and update here if it has been fixed.
hi @v-shex-msft thanks for the update. Also noticed today that % is also messed up
workaround for this is another measure:
% SLA Map = CONCATENATE(round([% SLA]*100,2),"%"
but it isn't great as the color saturation will not work properly on a text column.
