• What is the cause and solution for SAP error message CU873 - Design & already used in objects assigned to other classes ?

  The SAP error message CU873 ("Design & already used in objects assigned to other classes") typically occurs in the context of SAP's classification system. This error indicates that a design (or classification) object you are trying to create or modify is already being used in other classes, which prevents you from making changes to it.
  Cause:
  
  Existing Assignments: The design object you are trying to modify or delete is already assigned to one or more classes in the classification system.
  Data Integrity: SAP enforces data integrity rules to ensure that objects are not inadvertently modified or deleted if they are still in use elsewhere.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Assignments:
  
  Use transaction code CL02 (Change Class) or CL03 (Display Class) to check which classes the design object is assigned to.
  Identify all classes that are using the design object.
  
  
  
  Remove Assignments:
  
  If you need to modify or delete the design object, you will first need to remove it from all classes where it is currently assigned.
  Go to each class and remove the design object from the class assignments.
  
  
  
  Modify or Delete:
  
  Once the design object is no longer assigned to any classes, you should be able to modify or delete it without encountering the error.
  
  
  
  Reassign if Necessary:
  
  If you need to keep the design object but want to change its classification, you can reassign it to the appropriate classes after making your modifications.
