Hi,

I am calculation a 2 product systems. The first one, the upbuilding was finished, calculated, validated - fine. The second one has only Little changes (more Energy consumption, another material) - so that I copied the most parts of the first, copied and changed the names of the flows and also changed the Parameters. I checked different times, I have got all Connections, all "Lieferprozess", but if i calculate the product-systems I get no results, how can this be? Please can you give me some hints what could be wrong? Thank you very much,

Kind regards,

Lynn

Hi Lynn, I assume also the inventory results are zero? The reference unit you are calculating is not 0? Is the database valid? Which  database are you using?
