System conversion to S/4HANA best practices adoption in Logistic area

Hello,

we are currently in the process to convert a ECC system to a S/4HANA OP system (brownfield), and we would like to adopt some Best practices processes as CCM (rebates) in the target converted system, is it possible? How we need to set the client in the system? And how to implement the Best practices in there?

Thanks in advance for your help,

Best regards

Magdalena
