Hi Edwin,
Interesting question, I think SimaPro definitely cannot deal with ILCD data (but of course makes more marketing), we use openLCA to create ILCD compliant datasets, via the ILCD export. The openLCA fields need to be completed (for technology etc.) and the flows need to be the ILCD / EF flows (depending on which specific reference system you aim for). In openLCA 2, you can now apply a mapping in openLCA, or also while exporting.
Best wishes,
Andreas
