  Solution:
  
  Check Data Entry: Ensure that all required fields, especially the key fields, are populated with valid data before saving or processing the record.
  Review Configuration: If this error occurs during a specific transaction or process, review the configuration settings to ensure that all mandatory fields are correctly defined and populated.
  Debugging: If you have access to debugging tools, you can trace the program execution to identify where the empty value is being assigned to the key field.
  Consult Documentation: Refer to the SAP documentation or help resources for the specific module you are working with to understand the requirements for key fields.
  Data Validation: Implement data validation checks in your application to prevent users from submitting records with empty key fields.
  
  Related Information:
