Start the 'Costflow' action from the 'Print to PDF' menu.
The Costflow chart will be generated from the 'Calculation Results' table (from all of the results).
As you hover your mouse over the various distribution elements in the charts, you can interactively follow various parts of the cost flow.
For example, hover your mouse over the initial IT Budget Plan (1 507 000 EUR = the direct costs) (A) and move to the next (B) 'SAN Storage' distribution element. The whole path will be highlighted relative to the rest of the chart (see below).
The same applies if you proceed to the next distribution element (C) etc.
