Fields can be added to Crosstabs as row groups, or as column groups. Measures can be added to Crosstab rows or columns as well, but all measures must be included in a Crosstab as either a row or a column – that is, you can add one or more measures to the Crosstab as columns, or add one or more measures to the Crosstab as rows, but you cannot have one measure as a column and another as a row in the same Crosstab.
