• What is the cause and solution for SAP error message RA120 - Changes affect all MTEs. Use the methods belonging to this MTE class. ?

  The SAP error message RA120, which states "Changes affect all MTEs. Use the methods belonging to this MTE class," typically occurs in the context of monitoring and managing metrics in SAP systems, particularly when dealing with the Monitoring and Alerting Infrastructure (MAI) or the SAP Solution Manager.
  Cause:
  This error message is triggered when you attempt to make changes to a Monitoring Template Element (MTE) that would affect multiple MTEs at once.

  To resolve this error, you should follow these steps:
  
  
  Identify the MTE Class: Determine which MTE class you are working with and understand its structure and the specific MTEs it contains.
  
  
  Use Specific Methods: Instead of applying changes globally, use the methods that are specific to the MTE class. This may involve:
  
  Accessing the specific MTE instance you want to modify.
  Applying changes only to that instance rather than to all instances of the MTE class.
  
  
  
  Review Documentation: Consult the SAP documentation or help resources related to the specific MTE class you are working with. This can provide insights into the correct methods and practices for making changes.
