• What is the cause and solution for SAP error message AD890 - Activation could not be unlocked ?

  The SAP error message AD890, which states "Activation could not be unlocked," typically occurs during the activation of a transport request or when trying to activate an object in the ABAP Dictionary or other components. This error can arise due to various reasons, including issues with transport requests, locks on objects, or inconsistencies in the system.
  Causes:
  
  Transport Request Issues: The transport request may be locked or not properly released.
  Object Locks: The object you are trying to activate may be locked by another user or process.
  Inconsistent State: The system may be in an inconsistent state due to previous failed activations or transports.
  Authorization Issues: The user may not have the necessary authorizations to unlock or activate the object.
  Database Locks: There may be database-level locks preventing the activation.
  
  Solutions:
  
  
  Check Locks:
  
  Use transaction code SM12 to check for any locks on the object. If you find locks that are not needed, you can delete them (ensure you have the necessary authorizations to do this).
  
  
  
  Release Transport Request:
  
  Ensure that the transport request is released properly. You can check this in transaction SE09 or SE10. If the request is still in a modifiable state, release it.
  
  
  
  Check for Active Sessions:
  
  Use transaction SM66 to check if there are any active sessions that might be holding locks on the object. If you find any, you may need to coordinate with the users to resolve the issue.
  
  
  
  Re-activate the Object:
  
  Sometimes, simply trying to re-activate the object after resolving any locks can help. Use transaction SE11 or SE80 to navigate to the object and attempt activation again.
  
  
  
  Check Authorizations:
  
  Ensure that the user has the necessary authorizations to perform the activation. You can check this in transaction SU53 after the error occurs.
  
  
  
  System Consistency Check:
  
  If the issue persists, consider running a consistency check on the system. This can be done using transaction SE14 for database objects.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that might address this specific error. There may be patches or updates that resolve known issues.
  
  
  
  Restart the System:
  
  As a last resort, if the issue is not resolved, consider restarting the SAP system, as this can clear temporary locks and inconsistencies.
