Hi,

I regenerated a report model (just added a new field) and now the existing
reports created using Report Builder no longer run. I get the following
error:

An error has occurred during report processing.
Semantic query compilation failed: e EmptySemanticQuery The SemanticQuery
does not contain any Groupings or MeasureGroups. SemanticQuery must contain
at least one of these elements. (SemanticQuery '').

When I try to open the report in Report Builder, it does not see any of the
entities in the model. Instead, it displays "Unknown Entity".

How can I get the reports to be usable again?

Thanks,

Rocco M.
