Debugging SSRS Reports

By Becky Newell | March 17, 2013

If the Debugger will not break in your SQL Server Reporting Services Report and/or you want to speed up the debugging session by not printing the report and only stepping through the class logic, try the following steps:

  1. In the AOT under Tools > Options click the Development link and unmark the 'Execute business operations in CIL' checkbox
  2. Set breakpoints in the RDP class
  3. Manually invoke the RDP class via a job

RDP classes:
-Take contracts which sets their parameters
-Have processReport methods which act as the driver method in the class
-In a job create code like the following:

TmpTest tempTable; 
   //This is the temp table the RDP class populates and the one you want to view the contents of.
CustReportDP dataProvider = new CustReportDP(); 
   //This is the RDP class used by the report
CustReportContract contract = new CustReportContract(); 
  //This is the contract class used by the RDP class
contract.parmAccountNum('12345');  
  //The parm methods are on the contract become the parameters for the report
contract.parmCustGroup(10);
contract.parmCategory('Custom');
dataProvider.parmDataContract(contract);  //Send the contract to the RDP class
dataProvider.processReport();  //Execute the primary method in the RDP class
tempTable = dataProvider.getTmpABC(); 
//Get the populated temp table in order to view its contents.  
//Every RDP class has a get method for each temp table it populates.
while select tempTable  //View the contents of the table
{
  info(tempTable.AccountNum);
}

With this approach any breakpoints in the RDP class will definitely get hit as the debugger will run on the client side just like a normal debugging client session. Using the job will completely bypass the SSRS report but you can debug your logic and simulate the report behavior by passing the appropriate parameters.
