OK. I have two options, but I am looking for Curtain # 3.
1) If I publish in July, my month slicer will only show Jan through July at the time of the publish. I choose July in my slicer, publish, and that is what is in the service. In August, July is still the selected slicer option, so the visuals are based on last month, not this month. Only fix is to open the desktop, refresh, choose new month, republish. This is a pain.
2) I can base a visual on a date based measure, so i can have a visual that always shows current month, whatever the current month is. This is great, gives me what I want up front, but now isn't the visual stuck, and not sliceable anymore by month?
What would be ideal is to enable a slicer to self select the last month as default as part of the refresh, but be user selectable beyond that. Is there anyway to pull that off?
