Periodic or Year-to-date storage type in a consolidation data model

Hi BPC Experts,

We are now in the process of making a decision about using either Periodic or Year-to-date storage type in our consolidation data model.

What are the pros and cons of using the above 2 methods? What is the impact to the consolidation functionality?

Is there any way to translate Balance Sheet accounts on a cumulative basis if the periodic data storage type is used?

Thanks  a lot.
