BW connectivity in the Personal Edition (free version) is only supported for the trial period (30 days). But the actual functionality while the trial period is valid should have the same level of support. The only thing is that the 30 day trial does not come with the support and maintenance SLA.
But you can always contact support.lumira@sap.com
If you are also evaluating Lumira for future paid license opportunity I am sure we can find a way to help.
I will forward this to a couple of folks within SAP and see if anyone can assist.
Thanks
