CO Planning Version for Activity rate is disappeared?

Hi,

The Activity Rate Planning app does not have Plan version anymore. The new field that has been added is Ledger specific.

However, I would like to confirm that this is not available in Public Cloud and why?

This is OP /Private Cloud version

and we have more than 1 Plan version for simulation purpose.

This is Public Cloud version

So in this Manage Cost Rates - Plan app, you can specify the Ledger but not the version.

Does this mean that if customer wants to have simulation rates or more than 1 rate then we need to create a new ledger for it?
