This error indicates that there are inactive substructures within the specified structure that need to be activated before you can proceed with your operations.
  Cause:
  
  Inactive Substructures: The primary cause of this error is that there are substructures within the main structure that have not been activated. Inactive substructures can occur due to changes made in the data dictionary or when new fields or structures are added but not activated.

  Ensure that all dependent objects are also activated. Sometimes, a substructure may depend on another structure or table that is inactive.
  
  
  
  Transport Requests:
  
  If the changes were made in a development environment, ensure that the transport requests are properly released and imported into the target environment (like QA or Production).
  
  
  
  Recheck the Structure:
  
  After activation, recheck the structure to ensure that all components are active and there are no further issues.
