Symptom
No process instance can be started. I get the following error message:
Could not retrieve SDO HelperContext for service_id <...>
HINTS
The start even trigger cannot find an active process definition version.
- Log on to the SAP NetWeaver Administrator application (http://<host>:<port>/nwa) and choose Configuration → Processes and Tasks → Process Repository.
You can directly open the Process Repository application using the quick link, http://<host>:<port>/nwa/bpm-repository. - Activate manually one of the available process definition version (preferably the last deployed version).
