Suppliers - New Supplier Requests functionality

 Hi,

We have a requirement where internal users (within the organisation - NOT suppliers) need to be able to capture new supplier requests. I have noticed on a few documents on the internet that there is a new supplier request functionality available.

1. Does anyone have more details on it, what exactly can be captured on the new supplier request screen?
2. Which module does it fall under? Can you access it if you have Payables access or do you need iSupplier or Soucing or some other module of this sort?
3. I noticed that in a Vision environment, there is a hyperlink for 'New Supplier Requests' but it takes me to a search screen. I assume that there is a corresponding entry screen for a user to enter a new supplier request. How do i access it? Which responsibility do i use?
