• What is the cause and solution for SAP error message CN235 - Different controlling area for the reference and the new network ?

  The SAP error message CN235 ("Different controlling area for the reference and the new network") typically occurs in the context of project systems or network activities when there is an attempt to create or copy a network that references another network or activity from a different controlling area. This can happen in various scenarios, such as when you are trying to copy a network or when you are creating a new network based on an existing one.
  Cause:
  The error arises due to the following reasons:
  
  Different Controlling Areas: The reference network (the one you are trying to copy or reference) and the new network you are trying to create belong to different controlling areas. In SAP, controlling areas are used to manage costs and financial reporting, and they must be consistent for certain operations.
  Configuration Issues: There may be configuration settings in the project system that enforce this restriction, ensuring that networks and activities are only created within the same controlling area.
  
  Solution:
  To resolve the CN235 error, you can consider the following solutions:
  
  
  Check Controlling Areas:
  
  Verify the controlling area of the reference network and the new network you are trying to create. Ensure that both networks belong to the same controlling area.
  You can check the controlling area in the network details or by using transaction codes like CN21 (Create Network) or CN22 (Change Network).
  
  
  
  Create a New Network:
  
  If you need to create a new network in a different controlling area, you will have to create it from scratch instead of copying from the reference network.
  
  
  
  Change the Controlling Area:
  
  If it is appropriate for your business process, consider changing the controlling area of the reference network to match the new network's controlling area. This may involve more extensive changes and should be done with caution.
  
  
  
  Consult with SAP Support:
  
  If you are unsure about the implications of changing controlling areas or if the issue persists, it may be beneficial to consult with your SAP support team or a consultant who specializes in SAP Project Systems.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  CN21 - Create Network
  CN22 - Change Network
  CN23 - Display Network
  
  
  Documentation: Review SAP documentation related to Project Systems and controlling areas for a deeper understanding of how they interact.
  User Roles and Authorizations: Ensure that you have the necessary authorizations to create or modify networks in the desired controlling area.
  
  By following these steps, you should be able to resolve the CN235 error and proceed with your network creation or modification in SAP.
