CRM warranty products and related pricing

Dear Experts,

CRM 5.0

In our landscape, ECC is the leading system for product configuration and master data creation which then replicates into CRM. Now for a new business process we are planning to introduce warranties in CRM. I am aware of the standalone config for creating warranties in CRM but should the warranty products also be configured and created in ECC or can I go ahead and create them in CRM as we don't need the warranties to show in ECC.

Similarly, for pricing configuration, the leading system is ECC but we need to insert the pricing condition 1308 in CRM into the pricing procedure as it helps in warranty determination.

Could someone please advise how to achieve these?

Thanks

Ritwik
