• 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
