When you add a second rank to a different member on
the same crosstab axis, the second rank is applied to the results of the first
rank. Both ranks are in effect, and the crosstab displays only the rows or
columns that satisfy both rank conditions.
For example, if you apply a "Top 20" rank to one
member, and then apply a "Top 10" rank to another member on the same axis, the
crosstab displays the top 10 members out of those 20 members.
