Hi Raj,
in C4C (data model+UI) we distinguish (other then in ERP) beetween customer-employee relationships (called "account team" in the C4C UI) and "other relationships" (called relationships in the C4C UI). For "account team" relationships we support the sales area dependency with release 1502 (for other relationships not yet planned).
In general we currently only support data exchange for relationships (other then contact person relationship) in one direction (ERP->C4C) there is no bidirectional exchange.
Regards,
Markus
