  The SAP error message E4102, which states "Only delete function module includes using Function Builder," typically occurs when there is an attempt to delete a function module that is included in a function group or when there are issues related to the function module's dependencies.
  Cause:
  
  Function Module Dependencies: The function module you are trying to delete may be included in a function group or may have dependencies on other function modules or includes.
  Authorization Issues: The user may not have the necessary authorizations to delete function modules.
  Incorrect Deletion Method: The deletion might be attempted through the wrong transaction or method.

  Using transaction SE37 (Function Module) to view the function module.
  Checking the "Where-Used List" to see if it is referenced elsewhere.
  
  
  
  Use Function Builder: Ensure that you are using the Function Builder (transaction SE80) to delete the function module. This is the correct method for managing function modules and their includes.
  
  
  Authorization Check: Verify that you have the necessary authorizations to delete function modules. You may need to contact your SAP security administrator to ensure you have the right permissions.
  
  
  Remove Dependencies: If the function module is being used elsewhere, you may need to remove those dependencies first before attempting to delete it.
  
  
  Transport Requests: If the function module is part of a transport request, ensure that the transport is released and that you are working in the correct environment (development, quality, production).
