All, I am a Project Server newbie, so please bear with me. We have Microsoft Project Server 2007 instance and want to run a scheduler on the server to create Subtasks for some tasks (identified by a custom column value). The only way to do this is through the Project Server Interface (PSI) Web Service, right? Also, I am thinking of creating a Windows Service which runs on the Project Server machine calling the PSI Web Service. Is this approach correct? Is there a better approach? Regards, Harshu Kanitkar
