Within SAP Business Network, you have the capability to establish connections with multiple Business Applications on the buyer's side. Each of these business applications is uniquely identified by a System ID, which serves as a distinctive marker within SAP Business Network for routing purposes.
In a 2-system or 3-system Private Cloud landscape, you are required to create a System ID entry within the test SAP Business Network buyer account for the S/4HANA quality environment and another system ID entry within the production SAP Business Network buyer account for the S/4HANA Cloud Private Edition production instance.
The image below displays a user interface within the SAP Business Network's test environment, where two S/4HANA system IDs, "ED7CLNT800" and "EDP7CLNT850", are listed. One of them is marked as the default. The interface includes options for creating new system IDs and provides "end points" actions for each listed system ID. At the bottom of the interface, there are "save" and "close" buttons.

It's essential to ensure that your business applications (e. g. ERP backend systems) utilize the same System IDs as those you have configured in your buyer account to maintain seamless and consistent integration.
For detailed guidance on locating the System ID within your S/4HANA Cloud Private Edition instance and the steps to establish the entry in the buyer account, please follow the instructions of the accelerators.
Inside the buyer account you can check the entries under Click Account Settings → Manage Profile → Business Application ID's. Here you will find the overview with the System ID's.
