  The SAP error message SO2_TOOL151 indicates that a specified class does not exist in the system. This error typically occurs in the context of SAP's Object Services or when working with Business Object Processing Framework (BOPF) or similar functionalities where classes are expected to be defined and available.
  Cause:
  
  Missing Class Definition: The class that is being referenced in the transaction or program does not exist in the system. This could be due to a missing transport, an incomplete installation, or a misconfiguration.
  Incorrect Class Name: There may be a typo or incorrect naming in the class reference.
  Authorization Issues: The user may not have the necessary authorizations to access the class, leading to the perception that it does not exist.

  Solution:
  
  
  Check Class Existence:
  
  Use transaction code SE24 (Class Builder) to check if the class exists. Enter the class name and see if it is found.

  If the class is supposed to be part of a transport request, ensure that the transport has been successfully imported into the system.
