• What is the cause and solution for SAP error message CN468 - Subnetwork & for activity & not deleted ?

  The SAP error message CN468 typically indicates that a subnetwork (or network activity) cannot be deleted because it is still being referenced or has dependencies that prevent its deletion. This error is common in project management and network planning within SAP, particularly in the context of Project System (PS) or Controlling (CO) modules.
  Cause:
  
  Dependencies: The subnetwork or activity may have dependencies on other activities or networks that are still active or not completed.
  Status: The status of the network or activity may not allow for deletion. For example, if the network is in a status that prohibits changes (like "Released" or "Completed"), it cannot be deleted.
  Assignments: There may be assignments (like costs, resources, or other objects) linked to the subnetwork that need to be cleared before deletion.
  Authorizations: The user may not have the necessary authorizations to delete the subnetwork or activity.
  
  Solution:
  
  Check Dependencies: Review the dependencies of the subnetwork or activity. Ensure that there are no other activities or networks that reference it. You may need to delete or adjust these dependencies first.
  Change Status: If the network or activity is in a status that prevents deletion, consider changing its status to a more permissive one (like "Not Released") if your business process allows for it.
  Clear Assignments: Remove any assignments, costs, or resources linked to the subnetwork or activity. This may involve reallocating resources or costs to other activities or networks.
  Authorization Check: Ensure that you have the necessary permissions to delete the subnetwork or activity. If not, contact your SAP administrator to obtain the required authorizations.
  Use Transaction Codes: Utilize relevant transaction codes (like CN22 for changing networks or CN29 for deleting networks) to manage the network and its activities effectively.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes related to network and project management, such as CN01 (Create Network), CN02 (Change Network), CN03 (Display Network), and CN29 (Delete Network).
