  The SAP error message DDIC_ADT_SQSC027 with the description "Type interface &1 could not be deleted" typically occurs when there is an attempt to delete an interface in the ABAP Dictionary (DDIC) that cannot be removed due to various reasons. Here are some common causes, solutions, and related information for this error:
  Causes:
  
  
  Dependencies: The interface you are trying to delete may be in use by other objects, such as classes, methods, or other interfaces. If there are dependent objects, the system will prevent deletion to maintain data integrity.
  
  
  Transport Requests: If the interface is part of a transport request that is currently being processed or has not been released, it may not be possible to delete it.
  
  
  Authorization Issues: The user attempting to delete the interface may not have the necessary authorizations to perform this action.
  
  
  System Lock: The interface might be locked by another user or process, preventing deletion.
  
  
  Solutions:
  
  
  Check Dependencies: Use transaction SE80 or SE11 to check for any dependent objects that reference the interface. You can use the "Where-Used List" functionality to identify these dependencies. Remove or modify the dependent objects if necessary.
  
  
  Release Transport Requests: If the interface is part of a transport request, ensure that the request is released and not currently being processed.
  
  
  Check Authorizations: Verify that the user has the necessary authorizations to delete the interface. You may need to consult with your SAP security team to ensure proper roles and permissions are assigned.
  
  
  Unlock the Interface: If the interface is locked, you can check the lock entries using transaction SM12. If you find a lock that is preventing deletion, you may need to unlock it, but be cautious and ensure that it is safe to do so.
  
  
  Use Transaction SE80: Navigate to the interface in transaction SE80, and try to delete it from there. Sometimes, using the object navigator can provide more context or options.
  
  
  Consult SAP Notes: If the issue persists, check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
