  SAP Error Message:
  VN421 - Output cannot be edited! Only display of communication data!
  
  
  Cause:
  This error occurs when you try to edit the output communication data (such as partner communication details) in a transaction or output processing where the system only allows display (read-only) of the communication data. Typically, this happens because the output type or the processing status is set in a way that editing is not permitted.
  Common scenarios include:  
  
  The output is already processed or released for processing, so the system locks the communication data to prevent changes.  
  The output type configuration or the partner profile settings restrict editing of communication data.  
  The output is generated via a standard process where communication data is maintained centrally and cannot be changed in the output document.
  
  
  
  Solution:
  
  
  Check Output Status:
  Verify if the output is already processed or released. If yes, you cannot edit the communication data. You may need to cancel
