  Cause:
  
  
  Association with Basic IDoc Type: The primary reason for this error is that the IDoc extension you are trying to delete is still linked to a basic IDoc type. In SAP, IDoc extensions are used to add additional fields to the standard IDoc structure, and if they are still in use, they cannot be deleted.
  
  
  Active Usage: The extension might be actively used in various configurations, such as in message types, partner profiles, or other IDoc-related settings.
  
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Usage:
  
  Use transaction code WE30 (IDoc Types) to check if the extension is still associated with any basic IDoc types.
  Look for any message types or partner profiles that might be using the extension.

  Modifying the basic IDoc type to remove the extension.
  Updating any configurations that reference the extension.
  
  
  
  
  
  Delete the Extension:
  
  Once you have confirmed that the extension is no longer in use, you can attempt to delete it again using transaction code WE31 (IDoc Extension).
  
  
  
  Transport Considerations:
  
  If you are working in a development environment, ensure that any changes are properly transported to the quality and production environments.
