  The SAP error message /SCMB/TOOLS002 Class &1 does not implement interface &2 typically indicates that a specific class in the SAP system is expected to implement a certain interface, but it does not. This can occur in various scenarios, particularly when working with custom developments or enhancements in the SAP Supply Chain Management (SCM) module.
  Cause:
  
  Missing Implementation: The class specified in the error message does not implement the required interface. This could be due to a missing method or an incomplete implementation.
  Incorrect Class or Interface: The class or interface names may be incorrectly specified, leading to a mismatch.
  Transport Issues: If the class or interface was recently transported from another system, it may not have been properly activated or may be missing in the target system.
  Version Mismatch: There may be a version mismatch between the class and the interface, especially if the interface has been updated but the class has not.
  
  Solution:
  
  
  Check Class Implementation:
  
  Go to the ABAP Workbench (SE80) and check the class mentioned in the error message.
