I am trying to make a relationship class between two tables, but I get this message at the end:
Failed to create the specified relationship class
Can you tell me why?
Sorry I wasn't more precise: I use ArcEditor licence level, ArcGIS 10.0 version, and we're talking about a file geodatabase. I have a table for "ducts" and a table for "cables". A "duct feature" may have several "cable features", the forein key is the ID of the ducts. It's a one-to-many simple relationship.
