Hello,

I am stuck with a problem in my current modell which I remember to have had before but forgotten how it was resolved. In a production process modell several processes use a created material electricity and a sub-net delivers the exactly same electricity material but the connection will stay with negative stocks at end of calculation (causing an error). In my current specific model another connection stays with a wastewater material instead of pushing it forward to the WWTP process...
Any help would be very appreciated. Still I did not try to delete the material and create it anew because of quite a lot of uses and because I would like to see if you know the problem.
Here a temporary copy of the model:
