• What is the cause and solution for SAP error message DO748 - Append structure & was not deleted ?

  The SAP error message DO748 indicates that an append structure (a type of enhancement in SAP) was not deleted. This can occur in various scenarios, typically when trying to delete or modify a data structure that has dependencies or is being used in other parts of the system.
  Cause:
  
  Dependencies: The append structure may be in use by other objects, such as tables, views, or programs, which prevents its deletion.
  Authorization Issues: The user may not have the necessary authorizations to delete the append structure.
  Transport Issues: If the append structure is part of a transport request that has not been released or is still in use, it cannot be deleted.
  System Lock: The system might have a lock on the object due to ongoing processes or transactions.
  
  Solution:
  
  Check Dependencies: Use transaction SE11 (Data Dictionary) to check if the append structure is being used by any tables or views. If it is, you will need to remove those dependencies before you can delete the append structure.
  Authorization Check: Ensure that you have the necessary authorizations to delete the append structure. You may need to contact your SAP security administrator for assistance.
  Release Transport Requests: If the append structure is part of a transport request, ensure that the request is released and not in use.
  Remove Locks: Check for any locks on the object using transaction SM12. If there are locks, you may need to wait for them to be released or contact the user who has locked the object.
  Use Transaction SE14: If the append structure is related to a database table, you can use transaction SE14 (Database Utility) to check and adjust the database structure.
  Check for Active Sessions: Ensure that there are no active sessions or transactions that are using the append structure.
  
  Related Information:
  
  Append Structures: These are used to add fields to existing database tables without modifying the original table structure. They are commonly used for enhancements.
  Data Dictionary (SE11): This transaction allows you to view and manage database objects, including tables, views, and append structures.
  Transport Management System (STMS): This is used to manage transport requests in SAP, including the release and import of changes.
  Authorization Objects: Check the relevant authorization objects (e.g., S_TABU_CLI) to ensure you have the necessary permissions.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis team or refer to SAP Notes for more specific guidance related to your system version.
