• What is the cause and solution for SAP error message CN426 - Status and status change are ignored in manual activation ?

  The SAP error message CN426 ("Status and status change are ignored in manual activation") typically occurs in the context of project management or network activities within SAP, particularly when dealing with the activation of project structures or network activities in the Project System (PS) module.
  Cause:
  The error CN426 is generally triggered when you attempt to manually activate a project or network activity that has a status that does not allow for manual activation. This can happen for several reasons:
  
  
  Status Restrictions: The project or network activity may have a status that restricts changes. For example, if the status is set to "TECO" (Technically Completed) or "CLSD" (Closed), the system will not allow any further changes, including manual activation.
  
  
  Inconsistent Status: The status of the project or network activity may not be consistent with the expected workflow, leading to the system ignoring the manual activation request.
  
  
  Authorization Issues: The user may not have the necessary authorizations to change the status or activate the project/network.
  
  
  Solution:
  To resolve the CN426 error, you can take the following steps:
  
  
  Check Status: Review the current status of the project or network activity. If it is in a status that does not allow for manual activation (like TECO or CLSD), you will need to change the status to one that permits activation. This may involve reversing the status if possible.
  
  
  Change Status: If the status can be changed, use the appropriate transaction (like CJ20N for project management) to change the status to a valid one that allows for manual activation.
  
  
  Authorization Check: Ensure that you have the necessary authorizations to perform the activation. If you do not have the required permissions, contact your SAP security administrator to obtain the necessary access.
  
  
  Use Automatic Activation: If manual activation is not possible due to status restrictions, consider using automatic activation processes that may be available in your project management workflow.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific details on status management in the Project System module.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CJ20N (Project Builder), CN41 (Network Overview), and others that may help you manage project statuses.
  SAP Notes: Check SAP Notes for any known issues or patches related to the CN426 error.
  User Forums: Engage with SAP community forums or user groups for additional insights and solutions from other users who may have encountered the same issue.
  
  By following these steps, you should be able to address the CN426 error and successfully manage the activation of your project or network activities in SAP.
