When adding a representation to a feature class in an SDE geodatabase using the arcpy.AddRepresentation_cartography() function, the resulting representation prepends the database name and data owner (i.e. "databaseName.dataOwner.representationName"), which makes subsequent references to the same representation name originally defined fail as the new name is required in other scripting functions, for example, arcpy.SetLayerRepresentation_cartography().
