I had to put the link back, or rather, I had to add that table back to the DBC it was connected to. I remember my predecessor stating that he had removed some tables from the DBC and should have removed others; he thought this was neat stuff, so he took otherwise free tables and put them in the DBC, for no reason at all.
Anyway, my great plan to de-link the table backfired and I put it back into the DBC right away.
