Hi Marie,
I see, you will need to create a product system for each life cycle stage (so, A1, etc.) in openLCA and then calculate this separately, or you can combine the different product systems in one larger system for the entire life cycle, you can then see the different results in the analysis, and enter them e.g. in excel. This works quite fine, we use this in our projects as well. openLCA 2 will support this somewhat better, with a dedicated EPD object.
Best wishes,
Andreas
-it is not a collaboration server question though?
