Data for batch jobs scheduled server-side must be available to the SAS server.
Ideally, your data is stored on a shared network resource that is accessible both from your PC and the SAS server.
To do that in your environment, get in touch with your server/network/SAS admins.
Otherwise, you need to make sure that the file is copied to the SAS server in time.
A file import task in Enterprise Guide cannot be scheduled server-side; the code seen in this node is only reading the data after EG copied it to the server. The batch job can't do this copy, especially not when your PC is down.
