2911993 - Controlling access to Custom CDS View External API

• In a test scenario, a Custom CDS View has been created as an External API and a Communication Scenario, Arrangement, and User has been created to access the External API
• In Production, use of generic users is not permitted and the External API needs to be accessed by the business user using their own userid and password
• How can this be done?

SAP S/4HANA Cloud Public Edition

• An OData service can only be called by:

1. A Business User (with a Userid prefixed CB) if the OData service is added via an App and a Custom Catalog extension extending a Business Catalog and the user is assigned a role containing the same Business Catalog
2. A Communication User (with a Userid prefixed CC), if the OData service is part of a Communication Scenario and the user is used within the Communication Arrangement defined with the Communication Scenario

• The Production Scenario described in the Symptom section of this KBA would need to use option 1 while the test scenario uses option 2
