BP replication from CRM to ECC(FI-CA)

Hi Experts,

In my project, there is a requirement to replicate BP from SAP CRM to ECC (FI-CA).

I have created the necessary BP roles (MKK in ECC), assigned number ranges to Groupings,

Do I need to assign BP grouping to Customer Account Groups (IMG Path: Cross-Application Components / SAP Business Partner / Integration with Customer- /Vendor Master Data / Assign Business Partner Grouping to Customer Account Groups)?

Thanks in advance,

Anwesha.
