You can use label criteria to add descriptive information that corresponds to filter criteria you have defined in the rows and columns of the layout. When you define label criteria, you specify a tree node name or a detail value as the label source. PS/nVision uses this information to generate row and column labels automatically at runtime from detail or tree node records in the database. When you run the report, the rows and columns appear with their labels.
You can define label criteria at the row or column level. You cannot define them in any row or column that already contains other criteria types. To label filter criteria entered in the rows of the layout, specify the label criteria in an intersecting column; if you’re labeling filter criteria columns, put the label criteria in a row.
In this exercise, you will use the Label tab of the Layout Definition dialog box to specify label criteria for an existing matrix layout.
