Limited Sales Order Replication from ECC to CRM?

Hi,

I have a simple question: is it possible to replicate from ECC to CRM just the sales order headers? The target would be to have a CRM configuration that does not imply any products (neither created in CRM or replicated from the ECC system) but transfer sales data from the ECC system in the form of sales order headers.

So, is that possible?

Thank you,

Horatiu
