(Error(s) occurred while loading report: DSSSQLEngine: converting Report : The template in report is empty, or the objects on template can not be resolved. Please check report definition..Error in Process method of Component: SQLEngineServer, Project Strategy Tutorial, Job 26815, Error Code= -2147212797.)
STEPS TO REPRODUCE:

CAUSE:
The error message is not reproduced if the original Blank Report template is clicked. This is because the default template is associated with a predefined GUID, so even when the option to open in design mode is unchecked, it automatically opens the template in the design mode. Strategy Web senses that it has nothing on the template, and thus errors out.
ACTION:
Use original Blank Report template instead of using a copy of it to resolve the issue.
