• What is the cause and solution for SAP error message WY102 - Enter a characteristic of category CHAR ?

  SAP Error Message:
  
  WY102 - Enter a characteristic of category CHAR
  
  Cause:
  This error occurs when you are required to enter a characteristic value for a characteristic that is defined with the category CHAR (characteristic with single value) in a classification or variant configuration scenario, but the system detects that no value has been entered.
  In SAP Variant Configuration or Classification, characteristics can have different categories such as CHAR (single value), NUM (numeric), DATE, etc. When a characteristic is defined as CHAR, the system expects a single character/string value to be entered. If this is missing or left blank, the system throws the WY102 error.
  
  When does it occur?
  
  During classification of objects (e.g., materials, equipment, documents) when assigning characteristic values.
  In variant configuration when entering or maintaining characteristic values.
  When saving or processing a configuration or classification where a mandatory characteristic of category CHAR is empty.
  
  
  Solution:
  
  
  Enter a valid value for the characteristic:
  
  Go to the screen or transaction where the characteristic values are maintained.
  Find the characteristic that is causing the error (it will be of category CHAR).
  Enter a valid single value (string/character) for this characteristic.
  Save the data again.
  
  
  
  Check characteristic definition:
  
  Use transaction CT04 to display the characteristic.
  Verify that the characteristic is indeed of category CHAR.
  Check if the characteristic is set as mandatory in the class or configuration profile.
  If the characteristic is not supposed to be mandatory, adjust the class or configuration settings accordingly.
  
  
  
  Check class assignment:
  
  Use transaction CL02 to check the class and assigned characteristics.
  Ensure that the characteristic is correctly assigned and that the characteristic value is maintained.
  
  
  
  In variant configuration:
  
  If the characteristic is part of a variant configuration model, ensure that the configuration profile or dependencies do not require the characteristic to be filled in a scenario where it is not applicable.
  Adjust dependencies or default values if necessary.

  SAP Notes and Documentation:
  
  Check SAP Notes related to classification and variant configuration for any known issues.
  Refer to SAP Help Portal documentation on Classification and Variant Configuration.
  
  
  
  Typical Scenario:
  
  When classifying a material or equipment, if a characteristic of type CHAR is mandatory, the system will not allow saving without entering a value.
  In variant configuration, missing characteristic values for mandatory characteristics cause errors during configuration or order processing.
  
  
  
  
  Summary:
  
  Cause: Missing value for a mandatory characteristic of category CHAR.
  Solution: Enter a valid characteristic value before saving or processing.
  Check: Characteristic definition, class assignment, and configuration profile settings.
