3214634 - "Internal Server Error" when using "Data Export Service Open API" calls with grant type as "Authorization Code"

No further error message is present.


SAP Analytics Cloud Version 2022.8.10

Reproducing the Issue

Follow the instructions in the online help:

Select grant type: "Authorization Code" for Three-Legged OAuth authentication (business users).


Three-Legged OAuth allows business users to export smaller subsets of data while leveraging roles and data access privileges to ensure that they can only access data they have privileges for, at a model level.

This functionality is currently in preview mode and can be activated only after an official request to SAP.


Use two-legged authentication to test the API.

If you have an immediate business need that requires three-legged authentication, open an incident with SAP Product Support to validate your use case

If validated the functionality will be activated in your tenant.
