How to create Sankey diagram with identical dimension sets?

[Barn-Abbey]

Hi,

I would like to load two dimension columns (from and to) and a measure column into a Sankey diagram, with the two dimension columns having the same set of values (we are to display the migration of elements between categories through time).

Loading these columns into the chart I get the error message: Cycle found in rows: 0,1,2×

Is there some way to work around this obstacle?
