Re: How to set OOTB Part Attributes, Version & Iteration, using java code (Windchill API's) ?

Yes, it is possible to load objects out of sequence. For setting the version one can use  VersionControlSErverHerlper API's as shown below.

          VersionIdentifier vid = VersionIdentifier.newVersionIdentifier();

         VersionControlServerHelper.setVersionIdentifier(the_versioned, vid, false /* validateIncreasing */);

Similarly for iteration one can use IterationIdentifier API's. As shown below

           IterationIdentifier iid = IterationIdentifier.newIterationIdentifier();

            VersionControlHelper.setIterationIdentifier(the_iterated, iid);
