  The SAP error message CFD_DDIC_ADAPTER020, which states "Append Adapter: Deletion of append &1 failed," typically occurs when there is an issue with the deletion of an append structure in the Data Dictionary (DDIC). This can happen for several reasons, and understanding the cause is crucial for finding a solution.
  Causes:
  
  
  Dependencies: The append structure you are trying to delete may have dependencies, such as being used in a table or other structures. If there are active references to the append, the system will not allow its deletion.
  
  
  Transport Issues: If the append structure is part of a transport request that is not yet released or has been incorrectly imported, it may lead to inconsistencies.
  
  
  Authorization Issues: The user attempting to delete the append may not have the necessary authorizations to perform this action.
  
  
  Database Locks: There may be database locks on the table or append structure that prevent deletion.
  
  
  Inconsistent State: The system might be in an inconsistent state due to previous operations that were not completed successfully.
  
  
  Solutions:
  
  
  Check Dependencies: Use transaction SE11 (Data Dictionary) to check if the append structure is being used in any tables or other structures. If it is, you will need to remove those dependencies before attempting to delete the append.
  
  
  Release Transport Requests: Ensure that any transport requests related to the append structure are released and properly imported into the target system.
  
  
  Check Authorizations: Verify that the user has the necessary authorizations to delete append structures. You may need to consult with your SAP security team.
  
  
  Release Locks: Check for any database locks using transaction SM12. If there are locks, you may need to release them or wait until they are cleared.
  
  
  Consistency Check: Run a consistency check on the Data Dictionary using transaction SE14 to identify any inconsistencies that may be affecting the append structure.
  
  
  Use Transaction SE14: If the append structure is not being used, you can try to delete it using transaction SE14, which allows for more advanced operations on database objects.
