SAP C4C integration with multiple Backends( 2 ERP, 1 S/4 HANA on Premise)

[danijel_jovanovic86]

Hello experts,

we have the following problem: Currently we have 3 Backend Systems connected to the C4C System. Two SAP ERP Systems and one S/4 HANA OnPremise System.

Before the S/4 System was integrated, following BADI was already implemented RecipientSystemDeterminationbyBuinessObject in order to filter, to which Backendsystem the Business Partners should be sent to.

So far everything was working fine.

Now, after we have integrated the S/4 System with the C4C System, we have a problem where the Business Partner is not only sent to the correct SAP ERP System but it is also being sent to the S/4 System as well.

In the description of the BADI is says, that the BADI only works with the SAP ERP or SAP CRM-OnPremise systems.

My question is, can we use this BADI in our scenario("Business Partner Replication to SAP Business Suite"), or do we need to implement another BADI besides the one that we are already using? Or is there a BADI which can be used simultaneously for SAP ERP and SAP S/4 HANA OnPremise.

Best regards,
