Smart SAP Assistant

• What is the cause and solution for SAP error message CL787 - The hierarchy level of class & must be greater than & ?

  The SAP error message CL787 indicates that there is an issue with the hierarchy levels of classes in the classification system. Specifically, it means that the hierarchy level of the class you are trying to create or modify must be greater than the hierarchy level of the class it is being compared to. This typically occurs when you are trying to assign a subclass to a superclass incorrectly.
  Cause:
  
  Incorrect Hierarchy Assignment: You are attempting to assign a class to a higher level in the hierarchy than it currently exists. For example, if you have a class that is defined at level 2, you cannot assign it as a subclass to a class that is also at level 2 or lower.
  Misconfiguration: There may be a misconfiguration in the class hierarchy setup, leading to incorrect levels being assigned.
  Data Entry Error: A simple mistake in data entry when creating or modifying classes can lead to this error.
  
  Solution:
  
  Check Class Hierarchy: Review the hierarchy of the classes involved. Ensure that the class you are trying to assign has a higher hierarchy level than the class it is being assigned to.
  Adjust Class Levels: If necessary, adjust the hierarchy levels of the classes to ensure that the subclass is indeed at a lower level than the superclass.
  Recreate Class: If the class structure is too complex or incorrect, consider recreating the class with the correct hierarchy level.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on class hierarchy management.
  Use Transaction Codes: Use transaction codes like CL02 (Change Class) or CL03 (Display Class) to review and modify class settings.
  
  Related Information:
  
  Class Hierarchy: In SAP, classes are organized in a hierarchical structure where each class can have subclasses. The hierarchy is important for classification and categorization of materials, products, or other entities.
  Transaction Codes: Familiarize yourself with relevant transaction codes for managing classes, such as CL01 (Create Class), CL02 (Change Class), and CL03 (Display Class).
  SAP Notes: Check SAP Notes for any known issues or patches related to class hierarchy management that may provide additional insights or solutions.
  
  If the problem persists after following these steps, it may be beneficial to consult with your SAP support team or refer to SAP community forums for further assistance.
