Gros --
Generic resources do not have timesheets in PWA. Therefore, you would need
to make this resource a non-Generic resource in the Enterprise Resource Pool
and you would also need to make sure you do not enter a Windows Account for
that resources. When you save this resource, the system will create a user
account for the resource in PWA that uses Project Server authentication.
Whoever will enter time for that resource can log into Project Server using
the resource's User Name and the Password by default is blank. Hope this
helps.
