• What is the cause and solution for SAP error message CN662 - Access to work detail screen not allowed ?

  The SAP error message CN662 ("Access to work detail screen not allowed") typically occurs in the context of project management or controlling modules, particularly when users attempt to access detailed work information for a project or task without the necessary authorizations.
  Cause:
  The error is primarily caused by insufficient authorization for the user trying to access the work detail screen. This can happen due to:
  
  Authorization Issues: The user does not have the required roles or permissions assigned in their user profile to view the work detail screen.
  Configuration Settings: The system may be configured to restrict access to certain screens based on user roles or project settings.
  Project Status: The project or task may be in a status that restricts access to certain details.
  
  Solution:
  To resolve the CN662 error, you can take the following steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after encountering the error to see which authorization check failed.
  Review the user's roles and authorizations in transaction PFCG to ensure they have the necessary permissions to access the work detail screen.
  
  
  
  Adjust Role Assignments:
  
  If the user lacks the necessary authorizations, you may need to assign additional roles or modify existing roles to include the required permissions.
  Consult with your SAP security team or administrator to make these changes.
  
  
  
  Review Project Settings:
  
  Check if the project or task is in a status that allows access to the work detail screen. If the project is locked or in a closed status, access may be restricted.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific authorization objects related to project management and controlling to understand what permissions are needed.
  
  
  
  Testing:
  
  After making changes to authorizations or project settings, have the user log out and log back in to test if the issue is resolved.
  
  
  
  Related Information:
