Hello,

I have the following problem. Currently in the company I work there is a process for the generation of the Statements. This process  used rdlc files. This process runs every Saturday and has to generate approximately 5000 files. If the process is run locally (Development Environment) everything works fine, but when the process is running on a Server displays the following error: "invalid exception microsoft.reporting.definition the definition of the report '' is invalid on server "

I researched a bit and I made the following steps that recommend:
- Copy the following dlls in Bin.

Microsoft.ReportViewer.WinForms.dll

Microsoft.ReportViewer.WebForms.dll

Microsoft.ReportViewer.ProcessingObjectModel.dll

Microsoft.ReportViewer.DataVisualization.dll

Microsoft.ReportViewer.Common.dll

- Install the ReportViewer 2010 on the server.

In both cases the error always remains.

Could someone guide me in solving the problem?

Hi AJ.MurciaH,

Thank you for your question. 

I am trying to involve someone more familiar with this topic for a further look at this issue. Sometime delay might be expected from the job transferring. Your patience is greatly appreciated. 

Thank you for your understanding and support.
