MS CRM Reports can be accessed programmatically. But since MS CRM uses SQL Reporting Services, accessing reports is no CRM feature. Fortunately SRS exposes a webservice interface that you can use to do that. Further information can be found here:

There are several possible use cases. E.g. if you want to trigger report creation and delivery by MS CRM workflow. For this you have to create a .NET assembly that will be used in your workflow. Next you have to add a reference to ReportServer/ReportService.asmx. You can figure out the rest looking at the following code snippet:

reportingserver.ReportingService rs=new reportingserver.ReportingService();
rs.Url="http://yourhoust/ReportServer/ReportService.asmx";
rs.Credentials=System.Net.CredentialCache.DefaultCredentials;
 // or: new NetworkCredential("user", "pwd", "domainname");
    
byte[] result=null;
string reportPath="/yourorganizationname/reportname"; // adapt
string format="PDF"; // or XML, CSV, IMAGE, PDF, HTML4.0, HTML3.2, MHTML, EXCEL, and HTMLOWC
string historyID=null;
string devInfo=@"<DeviceInfo><Toolbar>False</Toolbar></DeviceInfo>";

ParameterValue[] parameters=null;

DataSourceCredentials[] credentials=null;
string showHideToggle=null;
string encoding;
string mimeType;
Warning[] warnings=null;
ParameterValue[] reportHistoryParameters=null;
string[] streamIDs=null;
SessionHeader sh=new SessionHeader();
rs.SessionHeaderValue=sh;

try
{
 result=rs.Render(reportPath, format, historyID, devInfo, parameters, credentials,
  showHideToggle, out encoding, out mimeType, out reportHistoryParameters, out warnings,
  out streamIDs);
}
catch(SoapException e)
{
 // ... 
}

// Write the contents of the report to a PDF file and mail it

try
{
 string filename=Path.Combine(Path.GetTempPath(), "report.pdf");
 FileStream stream=File.Create(filename, result.Length);
 stream.Write(result, 0, result.Length);
 stream.Close();

 MailMessage mm=new MailMessage();
 mm.To="whoever@wants.it"; 
 mm.From="reports@crm.com";
 mm.Subject="Report";
 mm.Body="... bla ... ";    
 MailAttachment att=new MailAttachment(filename);
 mm.Attachments.Add(att);

 SmtpMail.Send(mm);
}
catch ( Exception e )
{
 // ...
}
