I have a report that when viewed through the window in tessitura it gives the following error. " Execution "acpcin454sm3kq55pqbnyeqb cannot be found (rsExecutionNotFound)" When I close out of Tessitura and run it again it will open. If you go directly to the report link and run it it opens fine in Internet Explorer. Any idea what could be causing this error.
I occasionally see similar errors running SSRS reports if the report was modified while someone was already logged in to Tessitura. Relogging in has always resolved it.
