How To Fix CN797 - Simulations exist for the network(s)

SAP Error Message - Details

• Message type: E = Error

• Message class: CN - Meldungen für Netzpläne

• Message number: 797

• Message text: Simulations exist for the network(s)

What causes this issue?

You want to change an operative network. However there are active
simulations for this network. Changes to the operative network are not
updated inthe simualtion versions. Therefore when you transfer a
simulation version to the operative network, you could overwrite the
changes.

System Response

The system lets you make the changes to the operative system.

How to fix this error?

If you change the operative network, make the same chnages in the
simulation versions.

• What is the cause and solution for SAP error message CN797 - Simulations exist for the network(s) ?

  The SAP error message CN797, which states "Simulations exist for the network(s)," typically occurs in the context of project management and network planning within SAP. This error indicates that there are existing simulations for the network you are trying to process, which prevents certain actions from being completed.
  Cause:
  
  Existing Simulations: The primary cause of this error is that there are simulations associated with the network or project you are trying to modify or delete. Simulations are often used to test different scenarios without affecting the actual data.
  Locked Status: The network might be in a locked status due to ongoing simulations, which prevents changes to the network structure or data.
  Incomplete Simulation Processing: If a simulation was started but not completed or saved properly, it may still be flagged in the system.
  
  Solution:
  To resolve the CN797 error, you can take the following steps:
  
  
  Check for Active Simulations:
  
  Navigate to the network in question and check if there are any active simulations. You can do this by using transaction codes like CN22 (for network simulation) or CN41 (for network overview).
  
  
  
  Delete or Complete Simulations:
  
  If you find that there are simulations that are no longer needed, you can delete them. Use the appropriate transaction to delete the simulation.
  If the simulation is still relevant, ensure that it is completed and saved properly.
  
  
  
  Unlock the Network:
  
  If the network is locked due to simulations, you may need to unlock it. This can typically be done by completing or deleting the simulation.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to network planning and simulations for additional guidance on managing simulations.
  
  
  
  Contact SAP Support:
  
  If you are unable to resolve the issue on your own, consider reaching out to your SAP support team or consulting SAP Notes for any known issues or patches related to this error.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CN22, CN41, and CJ20N (Project Builder) for managing networks and simulations.
  SAP Notes: Check SAP Notes for any updates or specific fixes related to error CN797.
  User Permissions: Ensure that you have the necessary permissions to modify or delete simulations and networks in SAP.
  
  By following these steps, you should be able to resolve the CN797 error and proceed with your network planning activities in SAP.
