• What is the cause and solution for SAP error message TW063 - Shadow client & exists, remove from table T000 ?

  The SAP error message TW063 indicates that there is a shadow client that exists in the system, and it needs to be removed from the table T000. This typically occurs in the context of client administration in SAP systems, particularly when dealing with client copies, client deletions, or system refreshes.
  Cause:
  
  Shadow Client: A shadow client is a special type of client that is created during certain operations, such as client copies or system refreshes. It is not intended for regular use and is often used for temporary purposes.
  Client Deletion: If you are trying to delete a client or perform operations that require the client to be in a certain state, the presence of a shadow client can prevent these operations from completing successfully.
  Inconsistent State: The system may be in an inconsistent state due to previous operations that did not complete successfully, leaving behind a shadow client.
  
  Solution:
  To resolve the TW063 error, you need to remove the shadow client from the T000 table. Here are the steps to do this:
  
  
  Identify the Shadow Client:
  
  Use transaction code SE11 (Data Dictionary) or SE16 (Data Browser) to view the T000 table.
  Look for entries that indicate a shadow client. Typically, shadow clients have a specific client number and a status that indicates they are not active.
  
  
  
  Remove the Shadow Client:
  
  If you have the necessary authorizations, you can delete the shadow client entry directly from the T000 table. However, this should be done with caution.
  Use transaction code SE14 (Database Utility) to delete the shadow client entry. Make sure to back up any necessary data before performing this action.
  
  
  
  Check for Dependencies:
  
  Ensure that there are no other dependencies or processes that might be affected by the removal of the shadow client. This includes checking for any ongoing client copies or other operations.
  
  
  
  Restart the System:
  
  After removing the shadow client, it may be necessary to restart the SAP system or the relevant application server to ensure that all changes take effect.
  
  
  
  Consult Documentation:
  
  If you are unsure about the implications of removing a shadow client, consult SAP documentation or reach out to SAP support for guidance.
  
  
  
  Related Information:

  SAP Notes: Check for any relevant SAP Notes that might provide additional information or specific instructions related to the TW063 error.
  Backup: Always ensure that you have a backup of your data before making changes to the database, especially when deleting entries from system tables.
