S/4HANA Cloud Public Edition: Replication Mode in Communication Arrangement

[Simon]

Hello SAP Community,

i have a question regarding the replication model setting in the s4 Public Cloud. 

What does the Parameter Replication Mode "I - Initial Replication" in the Communication Arrangement( e.g. 0008 - Business Partner Replication) do ?

Does this also trigger a single "Initial Load" similiar to the App "Replicate by Replication Model" with mode "Initialization"

I did not find any specific information on the SAP Help.

Thanks in Advance

Simon

Hello Simon,

I'll just share my thoughts with you. From my understanding you first set the parameter to I (Initial Replication) in the communication arrangement to let the system know that you want to do an initial load. This by itself does not replicate anything yet. Then you can trigger the initial load in the app Replicate by Replication Model where you choose initial load again. If I understand correctly, that also means if you have the communication arrangement set to C and you want to run an initial load from the Replicate by Replication Model App, it does not work. But it's only from the top of my head, I didn't verify this right now. If this is incorrect, please let me know.

After that you would change the communication arrangement to C (Change Replication) so that changes will be captured. With output mode D (Direct Replication) the changes will be replicated directly and with output mode P (Pooled Replication) the changes will be gathered and the replication will be triggered later by a batch job. For that you have to maintain the job execution settings for the replication model in the communication arrangement.

In this guide at page 28 you can find some explanations for the basic settings in the communication arrangement 6KO_Set-Up_EN_XX.pdf

and here in 7. d. is some basic information about the output modes SAP-Help 

Kind regards,

Ni Niklas, thank you for your input. I did a bunch of testing the last few days and that are my results:

Initial Replication:

This deactivates the change pointer generation, but does not trigger any replication by itself.

You can do the initial load via app Replicate by Replication Model

Change Replication:

This does active the change pointer generation and depending on the output mode, the data gets replicated immediately or via the job.

The initial replication via Replicate by Replication Model is always possible, independently of the Replication Mode.
