Hi
The error you're encountering regarding authorization checks failure in your Hierarchy CDS view preview typically indicates that the user executing the preview does not have sufficient authorization to access or retrieve data from the underlying tables or entities used in the CDS view. Here are steps you can take to troubleshoot and potentially resolve this issue:
### Steps to Fix Authorization Checks Failure:
1. **Check User Authorization**:
- Ensure that the user you are using to preview the data has the necessary authorizations.
- In SAP Business Technology Platform (BTP) ABAP trial environment, users might need specific roles assigned to access and preview data from CDS views and underlying tables.
- Verify if the user has roles like `SAP_BC_DDL_READ`, `SAP_BC_DDL_EXECUTE`, or others relevant to CDS view access.
2. **Assign Required Roles**:
- If the roles are missing, assign them to the user. You can do this using transaction `SU01` (User Maintenance) in your ABAP environment.
- Alternatively, you might need to consult with your system administrator or refer to documentation specific to your BTP ABAP trial environment for recommended roles.
3. **Check CDS View Definitions**:
- Review the definition of your Hierarchy CDS view (`ZCDS_HIERARCHY` in your case).
- Ensure that all entities and associations used in the CDS view are correctly defined and accessible to the user.
4. **Authorization Trace**:
- Enable an authorization trace (`ST01` transaction in ABAP) to determine which authorization object is failing.
- Execute the data preview again and check the authorization trace logs (`ST01`) to identify the specific authorization object and values that are being checked.
5. **Adjust Authorizations**:
- Based on the authorization trace results, adjust the user's authorizations accordingly.
- It might involve adding additional authorization objects or values to existing roles or creating new roles specifically tailored for your CDS view access.
6. **Environment Specifics**:
- Since you are using a trial BTP ABAP tenant, ensure you are following any specific guidelines or limitations mentioned in the trial documentation.
- Sometimes, trial environments may have preconfigured roles or restrictions that could affect data access and preview capabilities.
7. **Consult SAP Community and Documentation**:
- If the issue persists, consider posting your specific problem on SAP Community forums or consulting SAP documentation related to CDS views and authorization management in ABAP environments.
### Example Steps in ABAP Environment (if roles are missing):
- **Assign Roles**:
- Go to `SU01` transaction.
- Enter the user ID and navigate to the "Roles" tab.
- Click on "Change" and add the necessary roles (e.g., `SAP_BC_DDL_READ`) if they are missing.
### Conclusion:
Addressing authorization check failures in SAP CDS view previews involves ensuring the user has the appropriate roles and authorizations to access the data. By following these steps, you should be able to diagnose and resolve the issue effectively. If the problem persists, consulting with your system administrator or seeking assistance from the SAP community can provide further insights tailored to your specific environment.
