• What is the cause and solution for SAP error message CL658 - You can only select characteristics for one class ?

  The SAP error message CL658 ("You can only select characteristics for one class") typically occurs when you are trying to select characteristics from multiple classes in a classification context, which is not allowed in SAP. This error is common when working with the classification system in SAP, particularly in the context of creating or modifying characteristics for classes.
  Cause:
  The error arises because the system restricts the selection of characteristics to only one class at a time. This is a design choice in SAP to maintain data integrity and ensure that characteristics are associated with a single class, which helps in avoiding confusion and potential data inconsistencies.
  Solution:
  To resolve this error, you should ensure that you are only selecting characteristics from one class at a time. Here are the steps you can take:
  
  
  Check Your Selection: Review the selection criteria you are using to ensure that you are not inadvertently trying to select characteristics from multiple classes.
  
  
  Single Class Selection: If you need to work with characteristics from different classes, you will need to perform separate operations for each class. For example, if you need to create or modify characteristics, do it one class at a time.
  
  
  Review Class Hierarchy: If you are working with a class hierarchy, ensure that you are aware of which class you are currently working with and that you are not mixing up characteristics from different classes.
  
  
  Use Transaction Codes: If you are using transaction codes (like CL02 for changing classes or CL03 for displaying classes), make sure you are in the correct transaction for the class you are working with.
  
  
  Consult Documentation: If you are unsure about the classification setup, refer to SAP documentation or help resources for guidance on how to properly manage characteristics and classes.
