Are you using the Notes entity or do you have a notes field on the entity you are reporting on?
Also, what tool are you using to generate the report?
If you are using advanced find or the report wizard, and you are using the Notes entity, there is no way to do this. "Does not Contain Data", means that the field exists, but there is no data in the field. If there are no Notes associated
with an entity, the record will not be returned by the query.
If you want to do this using the Notes entity and your are On Prem you can use SQL.
