to view the key figures from different perspectives. For example, they can switch from viewing the key figures over time to viewing the key figures by product group or by sales region. This process is called rotation because you are figuratively switching from the view of one dimension to another, as if you were rotating a cube.
have functions with which you can rotate the view by swapping the dimensions in the axes of the pivot table or (more visually clear) by swapping the horizontal and vertical dimension axes. Rotation is required for the slice and d ice analysis technique.
