Here’s a breakdown of the cause, potential solutions, and related information:

  Missing External Key: The external key that should correspond to the internal TU number is not available in the system. This could happen if the TU was not properly created or if there was an issue during the data transfer process.
  Data Inconsistency: There may be inconsistencies in the data between the EWM system and the connected systems (like SAP ERP or other external systems).

  Solution:
  
  Check TU Creation: Verify that the Transportation Unit has been created correctly in the system. Ensure that the external key is generated and linked to the internal TU.

  Review Configuration: Check the configuration settings for the integration between EWM and the external systems. Ensure that all necessary settings are correctly configured to allow for the mapping of internal and external keys.
  Recreate TU: If the TU is missing or incorrectly set up, consider recreating it to ensure that it generates the correct external key.
  Consult Logs: Review system logs for any additional error messages or warnings that could provide more context about the issue.
