To whom it may concern, while modelling with PEF I came across an issue with the sankey-diagram which always has one negative. This seems to be an issue of the process provider, as soon as I change the process provider another input turns negative in the sankey-diagram. Thank you, Ina

The connected flow (electricity?) is probably negative as well? Probably you have this situation also for other processes if you set the visibility threshold lower (capacitator, on the left, has also "gesamte Vorkette" < 0)? This is not an issue of the sankey diagram then but result of the model I think.

Best wishes,

Andreas
