In the Communication Arrangement app, for the Scenario ID: SAP_COM_0008 , for the Outbound Service - Business Partner - Replicate from SAP S/4HANA Cloud to Client, you defined the incorrect Replication Mode and Output Mode.


For the Scenario ID: SAP_COM_0008, if the Replication Mode is initial load, it is recommended to use Pooled Output as the Output Mode. Direct Output Mode is not recommended. After the initial load is done, the Replication Mode should be changed to Change Replication.

The initial load triggered by the Communication Arrangement could only be used in case of a low number of Business Partners as here the parallel processing option is not available. In case of a high number of Business Partners the initial load must be done via the App Replicate by Replication Model with the option Parallel Processing, where you should specify the Server Group and the Number of Processes for the replication.
