• What is the cause and solution for SAP error message WZ411 - Object type cannot be extended (subtype & used) ?

  SAP Error Message:
  WZ411 - Object type cannot be extended (subtype & used)
  
  
  Cause:
  This error occurs when you try to extend an object type in SAP that is either:
  
  Already used in a way that prevents extension, or  
  The subtype of the object type does not allow extension.
  
  In other words, the object type you are attempting to extend is locked or restricted because it is already in use or its design does not permit further extension.
  This is common in scenarios involving Business Object Repository (BOR) objects or when working with object types in the Workflow Builder or Object Navigator (SWO1).
  
  Explanation:
  
  Object types in SAP can have subtypes and can be extended to add new attributes or methods.
  However, if an object type is already used in workflows, applications, or other dependent objects, SAP restricts further extension to maintain consistency and avoid runtime errors.
  Also, some object types are defined as final or non-extendable by design.
