Domain role with multiplicity 0..1 or 1 can hold at most 1 link

I got the following error when I duplicate a SSRS report in Visual Studio:

Domain role with multiplicity 0..1 or 1 can hold at most 1 link: DataSetParameter of Microsoft.Dynamics.Framework.Design.Model.Reports.DataSetParameterRefersToParameter.

To resolve it do the following on the report datasets:

1. Change the datasource type to Query.
2. Delete the whole query text in the "Query" field.
3. Save, rebuild and change the values on the datasource back to the ones intended

Thanks to AlexDAX for this tip!

I also noticed the above actions can help resolve other problems, like inconsistency in the report parameters (can occur if you change the contract parameters).
