• What is the cause and solution for SAP error message WRF_APC007 - No characteristic values exist for material &1 ?

  Certainly! Here's a detailed explanation for the SAP error message WRF_APC007: No characteristic values exist for material &1:
  
  Error Message
  WRF_APC007: No characteristic values exist for material &1
  
  Cause
  This error occurs in SAP when the system tries to read or use classification characteristic values for a material, but no characteristic values have been maintained or assigned for that material in the classification system.
  In other words, the material is expected to have classification data (characteristics and their values) in the classification system (Class and Characteristics), but the system cannot find any characteristic values for the material.
  This typically happens in scenarios involving:
  
  Variant configuration (LOVC, VC)
  Classification-based material master data
  Integration with Advanced Planning and Optimization (APO)
  When using characteristics in BOMs, recipes, or formulas
  When the system tries to read classification data for a material but none exists
  
  
  Where it occurs
  
  During material master processing
  During variant configuration
  During APO integration or planning runs
  When reading classification data for a material in custom or standard programs
  
  
  Solution
  
  
  Check Classification Data for the Material:
  
  Go to transaction CL20N (Display Object Characteristics).
  Enter the material number and the relevant class.
  Verify if characteristic values exist for the material.
  If no characteristic values exist, you need to maintain them.
  
  
  
  Maintain Characteristic Values:
  
  Use transaction CL02 (Change Characteristics) or CL24N (Change Object Characteristics).
  Assign the material to the appropriate class (if not already assigned) using CL20N or material master classification tab.
  Maintain the characteristic values for the material.
  
  
  
  Check Class Assignment:
  
  Ensure the material is assigned to the correct class in the material master (MM02 ? Classification tab).
  The class should contain the relevant characteristics.
  
  
  
  Check Variant Configuration Setup (if applicable):
  
  If the error occurs during variant configuration, verify that the material has the correct class and characteristic values maintained.
  Check the configuration profile and dependencies.
  
  
  
  Check Integration Points:
  
  If the error occurs during APO or planning, ensure that the classification data is correctly replicated and maintained in APO.
  Run relevant CIF (Core Interface) transactions to synchronize data.
  
  
  
  Custom Code or User Exits:
  
  If the error occurs in custom programs, check the logic that reads classification data.
  Add error handling or checks to ensure characteristic values exist before processing.
  
  
  
  
  Additional Information
  
  
  Transaction Codes:
  
  CL20N – Display Object Characteristics
  CL24N – Change Object Characteristics
  CL02 – Change Characteristic
  MM02 – Change Material Master (Classification tab)
  CU50 – Change Variant Configuration Profile
  
  
  
  Tables involved:
  
  KLAH – Class header
  KSSK – Characteristic values for objects
  INOB – Object master (material as object)
  INOBT – Object to class assignment

  Summary
  
  
  
  Aspect
  Details
  
  
  
  
  Cause
  No characteristic values maintained for the material in the classification system.
  
  
  Effect
  System cannot find classification data for the material, causing error WRF_APC007.
  
  
  Solution
  Maintain characteristic values for the material in the classification system (CL24N).
  
  
  
  Ensure material is assigned to the correct class with characteristics.
  
  
  
  Verify variant configuration and APO integration if applicable.
