Step	Description
1.	The distributor sends a request for a discrete Ship-from-Stock and Debit (SSD) authorization and the component supplier responds; the response may approve or deny a product for the SSD. If the component supplier approves the authorization request, it may be approved only for a certain time period and specify effective and expiration dates. For blanket SSD authorizations, pre-order model 7 should be used.
