Inviting a supplier to an internal registration transfers access to external questionnaires from assigned internal recipients to the invited supplier contact. The supplier must now create an account or sign into an existing account on SAP Business Network to fill out the external questionnaires and submit them. When you first invite a supplier to an internal registration, you send them the external questionnaires for the first time, and those questionnaires close after the amount of time defined for new questionnaires in your site's questionnaire setup.
If the supplier was initially registered through an approved internal registration project, you can't change which external questionnaires are included in the registration when you invite the supplier to it. In this case, registration always contains the external questionnaires selected for the original internal registration. If the supplier was internally registered through a data import, you select the external questionnaires to include in the registration when inviting them to participate.
If the ability to specify a requester when inviting a supplier to register feature is enabled in your site, you can also choose the requester for the registration, such as an individual in your organization with whom the supplier is familiar or already has a relationship. The requester's name shows in the From field of registration invitations.
