The COMPUTAB Procedure

Example 9.2: Enhancing a Report

The following example shows how a report can be enhanced from a simple listing to a complex report. The simplest COMPUTAB report is a transposed listing of the data in the SAS data set INCOMREP shown in Output 9.2.1. To produce this output, nothing is specified except the PROC COMPUTAB statement and a TITLE statement.

To exclude the budgeted values from your report, select columns for ACTUAL observations only. To remove unwanted variables, specify the variables you want in a ROWS statement.

   title 'Column Selection by Month';
   
   proc computab data=incomrep;
      rows sales--other;
      columns jana feba mara;
      mnth = month(date);
      if type = 'ACTUAL';
         jana = mnth = 1;
         feba = mnth = 2;
         mara = mnth = 3;
   run;

The report is shown in Output 9.2.2.

To complete the report, compute new rows from existing rows. This is done in a row block (although it can also be done in the input block). Add a new column (QTR1) that accumulates all the actual data. The NOZERO option suppresses the zero column for March. The output produced by these statements is shown in Output 9.2.3.

   proc computab data=incomrep;
