Connecting on-prem clients to SAP

The Celonis on-prem client needs to establish a connection to the SAP system and be able to make RFC calls. For this purpose, we use an industry-standard library - The SAP Java Connector (SAP JCo), which is maintained and published by SAP. The JCo library should be downloaded and set up separately.

To connect to SAP:

  1. Download the respective package from the SAP Marketplace.


    Only SAP Service User (S User) can download software from SAP portals. Usually, a customer's SAP BASIS has this access.

    The downloaded jco folder already contains two files: a Java part “sapjco3.jar”, and an operating system-specific part e.g. sapjco3.[.dll | .so | .sl ].

  2. Copy the Library files directly into the external folder located at {installation_folder}/shared/libraries/external

    The Celonis Agent is configured to read the library from this directory.


    After setting up the jco, the Windows Service Celonis Agent needs to be restarted for the jco related changes to take effect.
