Changing multiple (two) field parameters with one button/slicer

Hi Anonymous !

I know this is a old topic, but I had the same problem, and your topic was top indexed on google, so I'll post how I solved it here, so it may help other people.
instead of using the code you thought of, you can use this one:

New_Parameter = {
    ("Timeframe 1", NAMEOF('Table1'[a]), 0, "TF 1"),
    ("Timeframe 2", NAMEOF('Table1'[b]), 1, "TF 2"),
    ("Timeframe 3", NAMEOF('Table1'[c]), 2, "TF 3"),
    ("Timeframe 1", NAMEOF('_Measures'[SankeyCount_timeframe1]), 3, "TF 1"),
    ("Timeframe 2", NAMEOF('_Measures'[SankeyCount_timeframe2]), 4, "TF 2"),
    ("Timeframe 3", NAMEOF('_Measures'[SankeyCount_timeframe3]), 5, "TF 3")
}


    

It will create a new column in the parameter, and you'll be able to put this new column on the segment, as will return only the group values.

It should work!
