• What is the cause and solution for SAP error message QS855 - You cannot use a classed characteristic in the material specification ?

  The SAP error message QS855 ("You cannot use a classed characteristic in the material specification") typically occurs when you are trying to assign a characteristic that is classified (i.e., belongs to a class) to a material specification in the context of Quality Management (QM) or Material Management (MM) in SAP.
  Cause:
  The error arises because classed characteristics are not allowed in material specifications. Classed characteristics are typically used in classification systems to categorize materials or objects, and they are not directly usable in specifications for materials. This restriction is in place to maintain data integrity and ensure that only appropriate characteristics are used in material specifications.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Characteristic: Verify if the characteristic you are trying to use is indeed a classed characteristic. You can do this by navigating to the classification system in SAP and checking the characteristics assigned to the class.
  
  
  Use Non-Classed Characteristics: If the characteristic is classed, you will need to use a non-classed characteristic instead. You can create a new characteristic that is not linked to any class or modify an existing one to ensure it is not classified.
  
  
  Modify Material Specification: If you need to include specific attributes in your material specification, consider creating a new specification that uses only non-classed characteristics.
  
  
  Consult Documentation: Review SAP documentation or help resources related to material specifications and characteristics to understand the limitations and best practices.
  
  
  Seek Help from SAP Support: If you are unsure about how to proceed or if the issue persists, consider reaching out to your SAP support team or consulting SAP Notes for any specific patches or updates related to this error.
