Product Costing for Different Controlling version

Hi,

I have two controlling versions.

In case of Version 0, i am maintaining plan costs, plan activity, and thereafter running standard cost estimation.

In Version 1, i am again maintaining separate set of plan costs, plan activity.

Do I need to create separate Costing version?

If yes, can anyone tell me the link between Costing version and Controlling version. Where exactly is the link?

Another query is, can I have the same standard cost of version 0 in version 1 as well?
