This typically occurs in the SAP Product Lifecycle Management (PLM) or SAP Material Management (MM) modules when dealing with characteristics of materials or products.
  Cause:
  The error arises when:
  
  You attempt to assign more than one value to an attribute that is defined as a single-value attribute in the classification system.
  The attribute is set up in such a way that it can only accept one value, but the input provided includes multiple values.
  
  Solution:
  To resolve this error, you should:
  
  Check the Attribute Definition: Go to the classification system and check the definition of the attribute in question. Ensure that it is indeed defined as a single-value attribute.
  Review Input Values: When entering values for the attribute, ensure that you are only providing one value. If you have multiple values, you need to determine which one is the correct or most relevant value to use.
  Modify Input Method: If you are using a program or transaction to input data, ensure that the method you are using is designed to handle single-value attributes correctly.
  Consult Documentation: If you are unsure about the attribute's purpose or the correct value to enter, consult the relevant SAP documentation or your organization's data governance policies.
