• What is the cause and solution for SAP error message WRF_APC149 - Material group &1 has more than one characteristic typed as &2 ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WRF_APC149: Material group &1 has more than one characteristic typed as &2
  
  Cause:
  This error occurs in SAP when you try to assign or process a material group that contains more than one characteristic of the same type (e.g., multiple characteristics of type "Quantity" or "String"). In SAP APC (Availability Planning and Control) or variant configuration contexts, each material group should have unique characteristics of each type to avoid ambiguity in classification or configuration.
  Specifically, the system expects that within a material group, characteristics are uniquely defined by their type. If two or more characteristics share the same type, the system cannot determine which characteristic to use, leading to this error.
  
  When does it occur?
  
  During classification or variant configuration setup.
  When assigning characteristics to material groups.
  While running planning or availability checks that involve material groups with characteristics.
  In APO (Advanced Planning and Optimization) or SCM (Supply Chain Management) environments where material groups are used for planning and characteristics are used for product attributes.
  
  
  Solution:
  
  
  Check the Material Group Characteristics:
  
  Go to the classification of the material group (transaction CL02 or CL20N).
  Review the list of characteristics assigned to the material group.
  Identify if there are multiple characteristics with the same characteristic type (e.g., multiple numeric or string characteristics).
  
  
  
  Remove or Consolidate Duplicate Characteristics:
  
  Remove the duplicate characteristics of the same type.
  If multiple characteristics are needed, ensure they have different types or are structured differently to avoid conflict.
  
  
  
  Adjust Characteristic Types:
  
  If possible, change the characteristic type so that each characteristic in the material group is unique by type.
  For example, if two characteristics are both numeric, consider if one can be changed to a different type or combined logically.
  
  
  
  Check Customizing and Master Data:
  
  Verify if the issue is due to incorrect master data or customizing settings.
  Consult with the master data team or configuration team to correct the characteristic assignments.
  
  
  
  Testing:
  
  After corrections, test the process again to ensure the error no longer occurs.
  
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  CL02 - Change Class (to edit characteristics assigned to material groups)
  CL20N - Class Maintenance
  MM01/MM02 - Material Master (to check material group assignment)
  APO Planning Transactions (e.g., /SAPAPO/MC9 for characteristic maintenance)
  
  
  
  SAP Notes and Documentation:
  
  Check SAP Notes related to APC and variant configuration for any known issues.
  Review SAP Help Portal documentation on Classification and Characteristics.
  
  
  
  Additional Tips:
  
  Ensure that characteristics are well-defined and documented.
  Maintain consistency in characteristic types across material groups.
  Coordinate with cross-functional teams (e.g., master data, planning, configuration) to maintain data integrity.
