slicing

In many reports, one dimension forms the rows, another forms the columns, and one or more of the remaining dimensions are used as slice dimensions. For example, in a report on product sales by region, the region dimension might form the rows and the product dimension the columns. If Sales Channel were the slice dimension, users could select different slices of the data to view by selecting different sales channels. In some reports, users can specify which dimensions form the columns and rows and which are used as slicers.
