Hi everybody,
I have ArcGIS for Desktop 10.3.1 (Advanced), I am trying to export my database (in SQL Server) with the XML exporting option, but an error appears:

This DB has 2 non-spatial tables,1 feature class and a relationship class between the feature class (points) and one of the non-spatial tables which was created using the geocode toolbar in order to locate addresses, I don't know if it happens because of the relationship.
I have exported my other DB without any problem.
I will appreciate if someone could help me with this issue.
