Thanks for this tidbit - I wouldn’t have thought to do that. Is there an up-to-date reference list anywhere columns that are supported, including those enabled through the “More Computed Columns with Big Tables” setting? Or do you just do trial and error and will there always be a warning like this if the computed column isn’t supported?
Thanks also for your post on Migrating. I had started the process and your suggestions on the order of operations are very helpful.
I was assuming that was the list without the preview feature checked. I also keep hearing that new columns are being added all the time, so I was looking for some specifics on what is added by the preview feature being checked.
