  Check Cluster Table Definition: Verify the definition of the cluster table in the Data Dictionary (transaction SE11). Ensure that the field you are trying to use is indeed a key field of the specified cluster.
  Modify Data Extraction Logic: If the field is not a key field, you will need to adjust your data extraction logic or reporting query to use the correct key fields that are defined for the cluster.
  Consult Documentation: Review the relevant SAP documentation or data model documentation to understand the structure of the cluster and the fields that are available for use.
  Debugging: If you are working with custom code or reports, consider debugging the code to identify where the incorrect field is being referenced and make necessary adjustments.
