Front-End Server and Back-End Server: Assign OData Service Authorizations to Users

You must assign OData service authorizations for the KPI to your users.

Several authorization default values are connected to the OData service. To ensure that all these default values are assigned to a user, you have to follow the instructions given under the documentation links provided.

End of the caution.

Make the assignment on the back-end server and on the front-end server:

On the back-end server, a dedicated authorization role (PFCG role) for the OData service is delivered as an example. You can copy this role and adjust it to your needs.
For more information, see Back-End Server: Assign OData Service Authorization to Users.
On the front-end server, you must assign the OData service authorization to a new or existing role, such as a business role that has been adjusted according to your needs.
For more information, see Add Start Authorizations for OData Services to Role on Front-End and Front-End Server: Assign Roles to Users.
