Hi All, Its have been quite a while that i didn't wrote a article. For last few weeks i was working on an assignment of SSRS Reports. With Assignment i was able to use the Great features of SQL, but at the same time there were some challenges due to simplicity in navision for Some specific points like Dates, Options, Flow fields etc. After Developing the Report when i host it on the Report Server and Tried to Run the Report, i faced the Error message - " Message: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500" In the Article below we will see how to resolve the Same.
