• What is the cause and solution for SAP error message CL480 - You can only make one entry here ?

  The SAP error message CL480 ("You can only make one entry here") typically occurs in the context of classification in SAP, particularly when working with class types and characteristics. This error indicates that the system expects only a single entry for a specific characteristic, but multiple entries have been attempted.
  Cause:
  
  Multiple Entries: The most common cause of this error is that the user is trying to enter multiple values for a characteristic that is defined to accept only one value.
  Configuration Settings: The characteristic in question may be configured in such a way that it is set to allow only a single value (e.g., a characteristic defined as "single value" in the class type).
  Data Entry Error: Users may inadvertently try to input multiple values in a field that is restricted to a single entry.
  
  Solution:
  
  Check Characteristic Configuration: Review the configuration of the characteristic in the class type. Ensure that it is set up correctly to allow only one entry if that is the intended design.
  Correct Data Entry: If you are trying to enter multiple values, you need to revise your input to comply with the single-entry requirement. Only enter one value for the characteristic.
  Review Class Assignment: Ensure that the class assignment and the characteristics associated with it are correctly defined and that you are not trying to assign multiple values where only one is allowed.
  Consult Documentation: If you are unsure about the configuration or the expected input, refer to the SAP documentation or consult with your SAP administrator for guidance.
