It sounds like you are receiving that error because of geometry issues with the features in the Parcel Fabric. This often happens when one stores the data in a file geodatabase and attempts to move the data to SDE. SDE contains stricter geometric rule enforcement for the data when copying it into an Enterprise geodatabase. I suggest you run Repair Geometry against all feature classes in the feature dataset containing the Parcel Fabric and then attempt to copy the feature dataset again.
Good Luck,
