001203 : There is no variation in any of the Analysis Fields.

Description

In order to discriminate among features for grouping purposes, the Analysis Fields you select should contain a range of numeric values. Any fields where all of the values are the same (all ones, for example) will be dropped from the analysis. In this case, none of the Analysis Fields you specified have variation.

Solution

Check if there is an active selection set where all of the features selected have the same values for the Analysis Fields. If so, change the selection to include features with more variation in the Analysis Fields. You can also include additional variables that will be more effective at discriminating among features.
