SYMPTOM
When browsing the elements of an attribute in the Data Explorer the error below is thrown:

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..

1. Create a new attribute in a three tier project source;
2. Still working in the three tier project source, go to the Data Explorer for that project and expand the System Hierarchy.
3. Find and click the attribute that was just created.

CAUSE
This issue happens when using the Data Explorer to browse the elements of a newly-created attribute that was created in a three tier project source without first updating the schema.
 
ACTION
The following must be done before a newly-created attribute can be used:

1. If the attribute is created in a three-tier project source, the schema needs to be updated;
2. If the attribute is created in a two-tier project source, the schema needs to be updated in 2-tier and then the 3-tier project needs to be reloaded.
