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.
