Strange errors in RoleTailored Client RDLC reports
We old dogs really have to learn new tricks with RTC (RoleTailored Client), as I found out couple of days ago. A customer of mine asked me for a quick report. I don’t typically do reports, but I thought—“not a big deal, it’s just a report”—so I fixed it, tested it, made sure it worked, then deployed it to production.
And then I found out it was not just a report.
It just didn’t want to execute in production. Whatever I did I just got a strange error message, something I never saw before. Ever.
