3616212 - Got error "Unexpected error occurred, please contact system admin for help." when import data from OData Service connection based on SAC Data Export API in SAP Analytics Cloud (SAC)

• Refresh import job or create a new import data model based on OData services connection using Data Export API from SAC failed with error message:
  • "Unexpected error occurred, please contact system admin for help."
• OData Service connection can be saved successfully.
• Metadata can be fetched successfully.
• Data service URL is https://{BaseURL}/providers/{NamespaceID}/{ProviderID}/, like "https://your-sac-tenant-url.cloud/api/v1/dataexport/providers/sac/QWERTY123456/"

SAP Analytics Cloud (Enterprise) 2025.8.6

1. Login to SAC.
2. Go to model.
3. Refresh the import job, failed and error message is 
   "Unexpected error occurred, please contact system admin for help."
4. Or create a new model based on the OData service connection based on SAC Data Export API.
5. Got the same error:
   "Unexpected error occurred, please contact system admin for help."

The Data Export API exposes metadata for every SAC model. This metadata is used to represent the SAC model structure using the OData v4 format. 

When using an import job via the OData service connection, the Data Acquisition Service consumes this metadata from the Data Export API using a 3rd party library called 'Olingo'.

When setting up an import from an OData data source, the Data Acquisition Service parses the metadata response from the Data Export API and based on the debugging of the error, the Olingo library was throwing an exception, as it was not able to parse the metadata provided by the Data Export API.

This is the exception which in turn blocked the import job from proceeding any further.

This issue is fixed by SAC development team.
