  The SAP error message GHO_BO001, which states "Network object & already exists," typically occurs in the context of project management or network planning within SAP. This error indicates that you are trying to create a network object (such as a network activity or a project network) that already exists in the system with the same identifier.
  Cause:
  
  
  Duplicate Entry: The most common cause is that the network object you are trying to create already exists in the database. This could happen if:
  
  You are attempting to create a network with an ID that has already been used.
  There was a previous transaction that created the network, and you are trying to create it again without realizing it.

  User Error: Users may inadvertently try to create a network object without checking if it already exists.
  
  
  Solution:
  
  
  Check Existing Objects: Before creating a new network object, check the existing network objects in the system to see if the one you are trying to create already exists. You can do this by:
  
  Using transaction codes like CN21 (Create Network) or CN22 (Change Network) to search for existing networks.
  Using the search functionality to look for the network ID.
  
  
  
  Use a Unique Identifier: If you find that the network object already exists, consider using a different identifier for the new network object you want to create.
  
  
  Delete or Modify Existing Object: If the existing network object is no longer needed, you may consider deleting it (if permissible) or modifying it to fit your requirements.
  
  
  Consult Documentation: Review SAP documentation or help files related to network management to ensure you are following the correct procedures for creating network objects.
