New OSS Communication for the connection to SAP’s Support Backbone

New Connection to SAP’s Support Backbone (OSS connection)

SAP’s support backbone or OSS connection, as it is also widely called, is the central infrastructure to provide technical support to SAP customers. The support backbone consists of several different systems for different purposes – for example, it provides the SAP Support Portal infrastructure, the Maintenance Planner, SAP EarlyWatch Alert Reports, and many more.

SAP’s support backbone has been updated. The legacy infrastructure remains in place to allow a safe transition. However, customers need to switch to the new infrastructure before January 2020 to ensure continuous connectivity.

Technically, the connection is changed from RFC-based to HTTPS-based communication.

This impacts every ABAP-based SAP system which is connected to the support backbone.
