You're probably best contacting your local Tech Support team in regards to a more authoritative response.
However, I would suspect that there is limited incentive for Schneider / AVEVA to integrate closer with Crystal Reports 2020.
There was some work done previously (a year or two ago) to introduce another reporting engine (Dream Reports), however that appears to have stagnated also.
Looking at the latest licence information from SAP on the Crystal Reports designer, I'm not even sure which licence version would be required. Thankfully it's normally our end-users that carry the licence for this product, so I'm a bit in the dark in regards to what licence they have.
