Error Type: SAP Authorization Error (SU53)

Common Cause: Missing or incorrect user authorizations

Immediate Fix:

1. Attempt the transaction that failed.
2. Immediately run transaction SU53 in a new session to capture the authorization error details.
3. Review the missing authorization objects displayed.
4. Share the SU53 output with your SAP security/admin team or use the SU53 Authorization Troubleshooter for automated analysis.
5. Once authorizations are updated, retry your transaction.

Understanding SAP Authorization Errors

SAP authorization errors occur when a user tries to perform an action or access data they don’t have permission for. The system immediately blocks the action and displays an error message, often prompting users to check their authorizations using transaction SU53.

These errors are a crucial part of SAP’s security model, but they can also disrupt work if not resolved quickly.

Common Causes

• User missing required authorization objects for a transaction or report
• Incorrect role assignment or outdated security roles
• Changes in security policy or SAP configuration
• Recent updates or new custom transactions without proper authorization mapping

Step-by-Step Solution

1. Reproduce the Error: Try the transaction or action again to make sure you trigger the authorization error.
2. Run SU53 Immediately: In a new SAP session, enter transaction code SU53. This will display the most recent authorization check failure for your user.
3. Analyze the SU53 Output: Look for the missing authorization objects and fields. The SU53 screen highlights exactly what was checked and failed.
4. Share with Security Team or Use a Support Tool: If you have access, use the SU53 Authorization Troubleshooter from ERPlingo for detailed guidance. Otherwise, send the SU53 screenshot or details to your SAP security/admin team for review.
5. Authorization Update: Once the missing permissions are added, retry your original transaction.
