  Review the CDS View Definition: Check the definition of the value help view in the ABAP Development Tools (ADT) or the relevant transaction. Ensure that the element causing the error is not defined as a key element.
  Adjust Annotations: If the element is incorrectly annotated, modify the annotations to ensure that it is treated as a non-key element. For example, you might need to remove the @Key annotation from the field.
  Consult Documentation: Refer to SAP documentation or guidelines on creating value help views to ensure compliance with best practices.
  Test Changes: After making the necessary adjustments, activate the CDS view and test it to ensure that the error is resolved.
