  The SAP error message LTR_MODEL_APPL104 indicates that there is an issue with a usage parameter that has been assigned to a non-existing table field. This typically occurs in the context of SAP's data modeling or data transfer processes, particularly when working with the SAP Landscape Transformation (SLT) or similar data replication tools.
  Cause:
  The error can be caused by several factors:
  
  Incorrect Configuration: The usage parameter is configured to point to a field that does not exist in the specified table. This could be due to a typo or an outdated reference.
  Changes in Data Model: If the underlying data model has changed (e.g., fields have been added, removed, or renamed), the usage parameter may no longer be valid.
  Transport Issues: If the configuration was transported from one system to another, it might not have included all necessary changes, leading to references to non-existent fields.
  Version Mismatch: If there are discrepancies between the versions of the source and target systems, it may lead to such errors.
  
  Solution:
  To resolve the error, you can follow these steps:

  Ensure that the field referenced in the error message exists and is correctly spelled.
  
  
  
  Update or Correct the Usage Parameter:
  
  If the field has been renamed or removed, update the usage parameter to point to the correct field.
  If necessary, create a new usage parameter that correctly references an existing field.
  
  
  
  Transport Consistency:
  
  If the issue arose after a transport, ensure that all related objects and configurations were transported correctly.
  Check for any missing dependencies that might not have been included in the transport request.

  Review SAP documentation or notes related to the specific module or functionality you are working with to see if there are any known issues or updates.
