• What is the cause and solution for SAP error message TK645 - User & is not authorized to change the owner ?

  The SAP error message TK645 indicates that a user is attempting to change the owner of a transport request but does not have the necessary authorization to perform this action. This is a common issue in SAP systems where transport requests are managed, and it typically arises due to authorization restrictions set in the system.
  Cause:
  
  Authorization Issues: The user does not have the required authorization object to change the owner of the transport request. This is often controlled by the authorization object S_TRANSPRT, which governs transport-related activities.
  Role Configuration: The user's role may not include the necessary permissions to change the owner of transport requests.
  Transport Request Status: The transport request may be in a status that does not allow changes to the owner (e.g., released or closed).
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to check which authorization is missing.
  Review the user's roles and authorizations to ensure they have the necessary permissions.
  
  
  
  Modify User Roles:
  
  If the user lacks the required authorization, a security administrator or someone with the appropriate permissions should update the user's roles to include the necessary authorizations.
  Ensure that the user has access to the S_TRANSPRT authorization object with the appropriate activity (e.g., 02 for change).
  
  
  
  Change Transport Request Status:
  
  If the transport request is in a status that does not allow changes, consider changing its status if appropriate (e.g., if it is still in development and can be modified).
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or your organization's internal guidelines for managing transport requests and user authorizations.
