Another case for Maxim 1:

From http://documentation.sas.com/?cdcId=pgmsascdc&cdcVersion=9.4_3.3&docsetId=proc&docsetTarget=p1g617vn...:

Requirement:

All variables in the TABLE statement must appear in either the VAR statement or the CLASS statement.

[ballardw · Accepted solution]

Proc tabulate needs to know how a particular variable is to be used. CLASS variables are for grouping, and by default will exclude records if the value for the class variable is missing. You can requested only count related statistics directly for Class variables such as N, PctN, RowPctN, ColPctN, RepPctN, PagePctN. VAR variables can have any of the available statistics requested but do not create groups or subgroups of results.
