A family of Microsoft relational database management systems designed for ease of use.
I apologize for giving you the impression that a "work around" of this size is reasonable. It is not!
For the company I work at, SSRS is part of our Calendar Year 2020 plan for reporting, so I decided to move in that direction now.... rather than wait on Microsoft to fix what I think can be called a bug.
I spent a few hundred hours of my time making a switchover to SSRS for reporting. This wasn't just time spent making reports in SSRS. It was time spent making a piece of middleware between my access applications and our SSRS server to handle requests --- for the case where there is one template, that is run with differing parameter values. We haven't Sql Server Enterprise, so I had to build middleware for something SSRS Enterprise can do.
As far as time requirements are concerned: I only converted two of the perhaps 300 reports I have to
SSRS. I converted only the reports that were likely to be effected by the "8 minute" problem.
Like you, I really would like a solution from Microsoft.
I simply felt I couldn't wait.
I appreciate your taking the time to share your experience and pain.
If others do, perhaps Microsoft will take notice.
