  The SAP error message CN249: Confirmation not possible - Save network first typically occurs in the context of project management and network activities within SAP. This error indicates that you are trying to confirm a network activity without first saving the network itself. Here’s a breakdown of the cause, solution, and related information for this error:
  Cause:
  
  Unsaved Changes: The network you are working on has unsaved changes. SAP requires that all changes to the network be saved before you can confirm any activities associated with it.
  Network Status: The network might be in a status that does not allow confirmations until it is saved.
  User Authorization: There may be restrictions on your user role that prevent you from saving the network or confirming activities.
  
  Solution:
  
  
  Save the Network: 
  
  Before attempting to confirm any activities, ensure that you save the network. You can do this by clicking the "Save" button (usually represented by a disk icon) in the SAP GUI.
  After saving, try to confirm the activity again.
  
  
  
  Check Network Status:

  If you are unable to save the network or if the issue persists, check with your SAP administrator to ensure that you have the necessary authorizations to perform these actions.
  
  
  
  Transaction Codes: 
  
  Use transaction codes like CN22 (Change Network) to make changes and save the network before confirming.
