How is walkup registration different from being invited?
The difference is when your account is reviewed and enabled by a buying organization. Invited suppliers are sponsored by a buying organization. Buying organizations send their suppliers email invitations that contain a link to the Ariba Supplier Network. This method associates the new suppliers with the appropriate buyers. After an invited supplier registers, the buyer is responsible for reviewing the supplier’s registration and activating the account. The supplier is notified through email when its account becomes active. Suppliers performing walkup registration are not associated with a buying organization. Before the account is fully activated, a buying organization must review and enable it.
