    Help with an if/then formula for a field

    matt.lukoff.0

      Hello,

       

      Can anyone help with a formula to create a string field in tableau for this logical statement

       

      Three ID Fields:

       

      ID1

      ID2

      ID3

       

      Use ID1 except if

      ID1 is null than use ID2.

      If ID2 is null than ID3.

      If all three are null than keep as null

       

      Thanks!
