CRM 2011 rsProcessingAborted error when running custom reports

Have you had a situation where the default reports in CRM 2011 and reports created from VisualStudio work, but reports created from the Report Wizard (or any Fetch based reports) result in a rsProcessingAborted error?

Product Review: InRule® for Microsoft Dynamics® CRM

Business logic can be applied to Dynamics CRM by a combination of these processes:

1. OOB workflows
2. Custom workflows

3. Plugins
4. JavaScript

Other than the OOB workflows (which has its constraints), the rest involve some knowledge of coding, with the plugins and workflows requiring background in C#. So if there is new requirement to create a business rule, typically the request is submitted to the IT/ Development team, and depending on their schedule the rule is created. If the rule needs changing, the business user needs to again reach out to someone outside of his/ her department.
