• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK379 - Entered Value Help View Field &1 not unique; can be mapped only once ?

  The SAP error message CFD_REGISTRY_CHECK379 indicates that there is an issue with the uniqueness of a value help view field in the context of a configuration or data entry process. This error typically arises when the system encounters a situation where a field that is supposed to provide a list of values (value help) is not unique, meaning that the same value can be mapped to multiple entries. This can lead to ambiguity in data selection and processing.
  Cause:
  
  Non-Unique Entries: The value help view field is returning multiple entries for a single input, which violates the requirement for uniqueness.
  Configuration Issues: There may be a misconfiguration in the data model or the way the value help is defined.
  Data Integrity Issues: The underlying data may have duplicates or inconsistencies that lead to non-unique mappings.
  
  Solution:
  
  Check Value Help Configuration: Review the configuration of the value help view. Ensure that the field definitions and mappings are set up correctly to enforce uniqueness.
  Data Cleanup: Investigate the underlying data for duplicates. If duplicates exist, you may need to clean up the data to ensure that each entry is unique.
  Adjust Field Definitions: If the field is meant to allow multiple values, consider adjusting the field definitions or the logic that handles the value help to accommodate this.
  Review Related Custom Code: If there is any custom code or enhancements related to the value help, review it to ensure it is not causing the issue.
  Consult Documentation: Refer to SAP documentation or notes related to the specific module or functionality you are working with for any known issues or additional guidance.
