• What is the cause and solution for SAP error message WRF_CHAR_VAL031 - Name (ATNAM) of characteristic &1 is missing ?

  SAP Error Message:
  
  WRF_CHAR_VAL031 - Name (ATNAM) of characteristic &1 is missing
  
  Cause:
  This error occurs when a characteristic (in classification or variant configuration) is expected to have a name (ATNAM), but the system finds it missing or empty. Essentially, the characteristic is referenced but its name attribute is not maintained or is blank.
  This can happen in scenarios such as:
  
  During classification or variant configuration processing where a characteristic is referenced but not properly defined.
  When data is being transferred or processed and characteristic metadata is incomplete.
  In custom developments or interfaces where characteristic data is manipulated or created programmatically but the name field is not filled.
  
  
  Explanation:
  
  ATNAM refers to the "Name of characteristic" in SAP classification/variant configuration.
  The system expects this field to be filled for each characteristic.
  If it is missing, the system cannot proceed with processing the characteristic, leading to this error.
  
  
  Solution:
  
  
  Check Characteristic Master Data:
  
  Go to transaction CT04 (Change Characteristic).
  Enter the characteristic name (the one referenced in the error message).
  Verify that the characteristic has a valid name and all required fields are maintained.
  Save if any missing data is added.
  
  
  
  Check Classification/Configuration Data:
  
  If the error occurs during classification or variant configuration, verify that all characteristics assigned to the class or variant have proper names.
  Use transaction CL02 (Change Class) to check assigned characteristics.
  
  
  
  Data Consistency Check:
  
  Run consistency checks on classification data if available.
  Check for any inconsistencies or incomplete entries.
  
  
  
  Custom Code / Interfaces:
  
  If the error arises from custom programs or interfaces (e.g., BAPIs, IDocs), ensure that the characteristic name (ATNAM) is correctly passed and not left blank.
  Debug the program to check the data flow and fill missing characteristic names.
  
  
  
  Transport or Data Migration:
  
  If the error occurs after a transport or data migration, verify that all characteristic data was correctly transported.
  Re-import or correct the characteristic master data if necessary.
  
  
  
  
  Additional Information:
  
  This error is related to SAP Classification and Variant Configuration modules.
  The characteristic name (ATNAM) is a key attribute and must always be maintained.
  The error message text is usually:
  
  "Name (ATNAM) of characteristic &1 is missing"
  
  where &1 is replaced by the characteristic ID.
  
  
  Summary:
  
  
  
  Aspect
  Details
  
  
  
  
  Cause
  Characteristic name (ATNAM) is missing or blank in classification/variant configuration.
  
  
  Solution
  Maintain characteristic name in CT04; check classification data; fix custom code if needed.
