  The SAP error message LTR2_KB_MODEL003 indicates that there is an issue with the assignment of a field structure to a logical field in the context of SAP's Logical Database (LDB) or data model configuration. Specifically, it means that the field structure you are trying to assign to the logical field is already assigned to another logical field, which is not allowed.

  Check Assignments: Review the assignments of field structures to logical fields in the relevant configuration. You can do this by navigating to the relevant transaction (e.g., SE11 for Data Dictionary) and checking the field structure assignments.
  
  
  Remove Duplicate Assignment: If you find that the field structure is indeed assigned to another logical field, you will need to either:
  
  Remove the existing assignment if it is not needed.
  Choose a different field structure that is not already assigned to another logical field.
  
  
  
  Adjust Logical Database Configuration: If you are working with a logical database, ensure that the configuration is set up correctly and that there are no conflicting assignments.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to properly configure logical databases and field structures.
  
  
  Testing: After making changes, test the configuration to ensure that the error is resolved and that the logical database functions as expected.
