Is the "szene" a single Editable Poly object? How many vertices are in the szene object? Is the szene material a single Multi/Sub-Object material, or are there multiple M/S-O's nested within each other?
Have you used a Reset Xform on the scene object, and then Collapsed the stack? Can you post a screenshot of the model? Have you tried restarting 3ds Max, then merging the object into a new scene file?
Apply the material to the new object before attaching. This will prevent the Attach Options dialog from appearing and modifying your Material IDs. (I'm assuming that by FaceID you mean Material ID, since you are dealing with materials.)
