I have to extend report's query to add a new field. I've created extension of a query, joined required datasources and can see new field in the list of fields. For some reason the report in the AOT is displaying with red cross sign:
In properties i can see error in metadata: "There was an error reading metadata. Make sure the metadata xml file(s) are accessible, are well formed and are not corrupted with duplicate or missing xml elements. The exception message is: Element named: 'Copy1' of type 'ModelElement' already exists among elements: 'Copy1'. Parameter name: item Additional information: AOT/Reports/Reports/WHSInvent"
There is an .xml of that object in packages local directory, there are no any duplicate names in any node of that report.
Any ideas how it can be fixed?
