great, thanks.

In the meantime, I updated the whole company. The one test database actually was the only database that this was returned. I found no other occurrences.

As I understand it, the worst thing that could happen is that one or more rows end up in a detached partition table which should actually be in another partition, right? Since there were no rows, no harm could have been done. Also, since this is a self reference, the wrong table is also the right one.

Again, thanks very much for clarifying this.

Cheers
Paul
