0032914: Data Exchange - Some parts of compound are lost while writing STEP in nonmanifold mode

Browse Source 
Code related to supporting of single SDR for a non-manifold group, which prevents writing all translation results except the first one, is removed.
SDRs with null used representation object are excluded from writing.
