Sales Area Dependent Relationships not replicated from C4C to ERP

Hi C4C guru's,

Since Release 1602 it should be possible to replicate sales area dependent relationships from C4C to ERP.

We have activated a particular relationship code in fine-tuning as sales area dependent. This relationship code is mapped to corresponding ERP partner function.

We have re-activated the communication arrangements "Business Partner Replication to SAP ERP".

Unfortunately the sales area dependent relationships are not replicated from C4C to ERP. The other way around (ERP>C4C) for this relationship type works fine.

Any suggestions how to activate the replication of sales area dependent relationships from C4C to ERP for customers?

Thanks!
