Smart SAP Assistant

• What is the cause and solution for SAP error message CL354 - Class "&" has subordinate classes ?

  The SAP error message CL354 indicates that you are trying to delete a class (denoted by "&") that has subordinate classes. In SAP, a class can have subclasses, and you cannot delete a class if it has any subclasses associated with it. This is a safeguard to maintain the integrity of the class hierarchy.
  Cause:
  
  The class you are attempting to delete is a parent class that has one or more subclasses defined under it. SAP does not allow the deletion of a class that has dependencies, as this could lead to inconsistencies in the class structure.
  
  Solution:
  To resolve this error, you need to follow these steps:
  
  
  Identify Subordinate Classes: 
  
  Use transaction code SE24 (Class Builder) to view the class in question. Check for any subclasses that are defined under it.
  
  
  
  Delete Subordinate Classes: 
  
  If you determine that the subordinate classes are no longer needed, you can delete them first. Make sure to check if they are being used anywhere in your system before deletion.
  
  
  
  Delete the Parent Class: 
  
  Once all subordinate classes have been deleted, you can then proceed to delete the parent class.
  
  
  
  Alternative Approach: 
  
  If you do not want to delete the subordinate classes, consider whether you can simply deactivate or rename the parent class instead of deleting it.
