Model backup in Oracle Configurator

Hi All,

I have tried to keep model backup in oracle Configurator Developer.

M is the model,copied the model to different folder and renamed it M_C.

I checked that unless and until any rules,UI  are changed in the model level of M_C.....its remain to be the backup of model M.

And also unless i click  repopulate button.my new items  added in CZ Item Master wont reflect in the Model.

But now i am checking if i edit the properties of the Item types in CZ Item Master,its automatically reflecting in all models without clicking repopulate.
