You want to swap the axes (rows and columns) in the analysis grid. You want to move the Distribution Channel characteristic from the rows to the columns, and the key figure structure from the columns to the rows.
In the navigation pane, drag the Rows entry to the Columns entry.
You can also do this by choosing Change Drilldown → Swap Axes in the context menu for a cell in the analysis grid or in the context menu in the navigation pane.
The analysis grid is updated accordingly: The key figures are now in the rows and the Distribution Channel is in the columns.
