  Error Message: WZ151 - Object key has changed
  
  
  Cause:
  This error typically occurs when you try to update or save an object (such as a document, master data record, or transaction) in SAP, but the key fields of the object have been changed during the process. In SAP, the key fields uniquely identify an object, and changing these keys is generally not allowed because it would mean you are trying to change the identity of the object rather than its attributes.
  Common scenarios causing this error:
  
  The user or a program attempts to modify the primary key fields of an object.
  The object was changed or updated by another user or process between the time it was read and the time you tried to save it.
  A custom enhancement or user exit incorrectly modifies key fields.
  Data inconsistencies or incorrect handling in BAPIs
