  The SAP error message /ISDFPS/LM_PM_ADDON158 External ID & is already being used in other flights typically occurs in the context of flight management or logistics within the SAP system, particularly when dealing with flight planning or scheduling modules. This error indicates that the external ID you are trying to use for a flight is already associated with another flight in the system, which prevents you from using it again for a different flight.
  Cause:
  
  Duplicate External ID: The external ID you are trying to assign to a flight is already in use by another flight. This could happen if the ID is not unique or if there was an error in data entry.
  Data Integrity Issues: There may be issues with data integrity in the system, where the same ID is being referenced incorrectly.
  System Configuration: The system may be configured to enforce unique external IDs for flights, which is a common practice to avoid confusion and ensure data accuracy.
  
  Solution:
  
  Check Existing Flights: Verify if the external ID is indeed being used by another flight. You can do this by querying the flight records in the system.
  Use a Different External ID: If the external ID is already in use, consider using a different, unique external ID for the new flight.
  Data Cleanup: If you find that the external ID is incorrectly associated with multiple flights, you may need to clean up the data. This could involve removing or updating the existing flight records that are incorrectly using the same external ID.
  Consult Documentation: Review the relevant SAP documentation or configuration settings to understand how external IDs are managed in your specific implementation.
  Contact Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with an SAP expert who can provide guidance based on your specific system configuration.
  
  Related Information:
  
  SAP Modules: This error is likely related to modules such as SAP Logistics (LO), SAP Transportation Management (TM), or SAP Aviation Management, depending on your organization's implementation.
  Transaction Codes: Familiarize yourself with relevant transaction codes that may help you navigate flight records, such as SE16 for data browsing or specific transaction codes related to flight management.
  User Permissions: Ensure that you have the necessary permissions to view and modify flight records in the system, as restrictions may also lead to errors.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
