On the left side, you can type the value for each split level.
Type the values in the text box. If you want to specify an SQL null-value, select NULL-value.
On the right side, you can edit the slice name, the result column name, and the description of the slice.
Make sure that the specified values are compatible with the data types of the split level columns.
If you are editing the default slice, you cannot edit the values on the left side of the dialog. The default slice contains all value combinations that are not mentioned in other slices.
