  The SAP error message ESH_AU_AUTHORIZATION020 typically occurs in the context of the Enterprise Search (ESH) component when there is an issue with user invalidation in the ESH shared memory for a specific client. This error can arise due to various reasons related to authorization and user management.
  Cause:
  
  Authorization Issues: The user attempting to perform the invalidation may not have the necessary authorizations to execute the operation.
  Client-Specific Issues: The error may be specific to the client mentioned in the error message, indicating that there might be a configuration or data issue within that client.
  Shared Memory Problems: There could be issues with the ESH shared memory itself, such as corruption or misconfiguration.
  User Locking: The user might be locked or inactive in the system, preventing the invalidation process from completing successfully.
  
  Solution:
  
  Check Authorizations: Ensure that the user has the required authorizations to perform the invalidation operation. You can do this by checking the user's roles and authorizations in transaction SU01 or SU53.
  Client Configuration: Verify the configuration of the client mentioned in the error message. Ensure that the ESH settings are correctly configured for that client.
  Shared Memory Management: If there are issues with the ESH shared memory, you may need to clear or refresh it. This can sometimes be done through transaction codes like SM12 (to check for locks) or SM21 (to check system logs).
  User Status: Check the status of the user in question. If the user is locked or inactive, you may need to unlock or activate the user account.
  System Logs: Review the system logs (transaction SLG1) for any additional error messages or warnings that could provide more context about the issue.
  Restart ESH Services: In some cases, restarting the ESH services or the entire application server may resolve transient issues related to shared memory.
