  SAP Error Message:
  WRF_APC153: Select a material group. Class &1 is typed as &2
  
  Cause:
  This error occurs when you are trying to assign or use a class in a context where a material group is expected, but the class type does not correspond to a material group. In SAP, classes are categorized by types (e.g., material class, document class, equipment class, etc.). The system expects a class of a specific type (usually material class, type 001), but the class you have entered is of a different type.
  
  &1 = Class name you entered  
  &2 = Class type of the entered class (e.g., 002 for document class, 003 for equipment class, etc.)
  
  For example, if you are in a transaction or process that requires a material class (type 001), but you enter a class of type 002 (document class), the system throws this error.
  
  Solution:
  
  
  Check the class type:
  
  Verify the class type of the class you are trying to use. You can do this by:
  
  Using transaction CL02 (Change Class) or CL03 (Display Class) and entering the class name.
  Check the class type field to confirm if it is a material class (type 001).
  
  
  
  Use the correct class type:
  
  If the process requires a material class, ensure you select or create a class of type 001 (Material class).
  
  
  Assign the correct material group:
  
  If the error message suggests selecting a material group, ensure that the material group is assigned properly in the material master or classification.
  
  
  Adjust your input:
  
  When prompted to select a material group or class, make sure you input a class of the correct type.

  CL03 - Display Class

  Material groups are used to classify materials for reporting and selection purposes. They are maintained in the material master and can be linked to classes.
  
  
  Classification in SAP:
  
  Classification allows you to assign characteristics to materials or other objects using classes. The class type must match the object type.
  
  
  
  Summary:
