  Solution:
  
  Check Configuration: Review the configuration of the superior key component in both the source and target systems. Ensure that the destination type is correctly set up to accept the key component.
  Adjust Data Model: If there are discrepancies in the data model, consider adjusting the data model in the target system to align with the source system. This may involve modifying the structure of tables or fields.
  Review Mapping: Go through the mapping of fields in the SLT configuration. Ensure that all key fields are correctly mapped and that there are no conflicts in data types or structures.
  Reassign Destination Type: If necessary, reassign the superior key component to the correct destination type that matches the target system's requirements.
