Hi,
already you added the one object in transformation level.
While activating the transformation ti will give only warning not an issue.
are you getting any error while transformation activating before activate the data source, dso, ic active then activate the transformation.
if want full load the info cube drop the data then run the full load again it will populate new object data also.
if you are getting any issue please send screen shot to us.
Thanks,
PHani.
