Oracle Configurator

Hi all

I would like to explore O2C flow with models. in my current project we dont have any models(ATO,PTO,CTO etc.)

but i hope i can create these models.

i create a simple PTO model  with option class ( with 1 option class with 2 standard items)  and 2 standard items.

While creating a sales order with the above model while clicking on the configuarator button at sales order line level-  iam not getting the configurator page.

Can you please some share the per-requisits for Oracle configurator module.

Thanks &Regards
