I recently created 2 additional relationship classes between one of my SDE tables and 2 feature classes. Since doing this I cannot upload the data as a feature service, I get a "Consolidating the Data Failed" error. I've found that removing one of the relationship classes so that there is only one relationship referencing the database table allows it to upload. Is this a known bug where a feature service cannot have multiple relationship classes using the same data source? Is there a known workaround other than creating a redundant database table for the second relationship class?
