SAP Universal ID

The concept provided is undefined, and the supplied sources do not describe a specific, identifiable SAP developer concept. Source [S1] covers troubleshooting token retrieval failures with a 401 status code, [S2] describes creating SAP user accounts to grant authorizations via the default identity provider, [S3] provides troubleshooting guidance for the btp CLI, and [S4] references the SAP Community tour — none of which point to a single coherent concept. A valid concept name is required to produce an accurate reference definition grounded in these sources.
