Sounds lik eit's in there then. If you look on a parts diagram of a 996 for example or 900 SS, available from ducati.com, take a look at the crankcase diagram and you'll see a small plate fitted under the oil filter spigot.
when you next have the filter off, look up inside the where the filter screws in and you'll see if it's there.
