RFQ - Internal or External

hello !

IS RFQ an internal or an external doc.?

Practically speaking RFQ is a doc. that we send to suppliers to ask for their quoatations and comparison after that...

In SAP, can RFQ be used to get the quotations from supplier and do a price comparison? Is yes, how the quotation that we get from a supplier is fed into SAP.

Thanks
