Hi,
I am trying to calculate the analysis of a product system but I always get an unexpected error caused by Lexical error at line 1, column 15. Encountered: <EOF> after : ""
How can I fix it?

Thank you in advance!

The log file shows this:

Hi, well this is of course a bit hard to solve from the information you provide, - which database are you using, which product system, which version of openLCA, ... did you do any other modification of the database? If the database and model are ok the analysis works; and openLCA contains measures to prevent ill-specified databases and models, but you can of course change things with the SQL editor for example.
Please let us know.
Thanks,
Andreas

Hi,

well that's my very first LCA and I'm modelling the production of tomatoes (cradle-to-grave). I'm using the ProBas database and the latest version of openLCA. I didn't do any modifications. It seems like there was an error in one of the processes I imported from ecoinvent. I deleted that process, now it is possible to calculate the product system. But a lot of processes in my product system show negative LCIA relusts. How is it possible that one process has only negative values in all impact categories?

Thank you very much in advance!
Kind Regards

Ah thank you - but then you combine ecoinvent (which version, from where - not from nexus I think) with ProbBas? In ProBas, system expansion is quite often used which can lead to negative values.
Hope this helps!
