After CRM Upgrade from 4 to CRM 5.0, when we create the BP in CRM Web Client BPs are not replicating to ECC (ECC 5.0). In SMW01 transaction, status is showing as green (Confirmed, Fully processed by all receivers), but BP is not getting replicated to ECC

Appreciate if anybody could help with your suggestions or solution.

Thanks
