  3. Configure SAP Launchpad Service in BTP
  4. Configure SAP On-Premise system

 

1.   Configure Cloud Connector with S/4HANA On-Premise System

Email or Username to be used as subject pattern for principal propagation between My Inbox On-Premise application and SAP Launchpad service in BTP using cloud connector

1.1  Register Cloud Connector to the subaccount using S-user

1.2  Configure Cloud to On-Premise connection using https protocol with X.509 certificate for Principal type.

Conclusion

This blog outlines the steps involved in integrating My Inbox app in on-premise environment with SAP Launchpad service in BTP and this integration enables a channel to process request of an on-premise system in private network using BTP Cloud service in public network or using SAP Start Mobile Application.

The same process and steps are applicable for other SAPUI5 apps as well.

The SAP Note 3042853 provides additional information on restrictions in integrating on-premise applications with SAP Launchpad Service.
