This activity is used to add information about contact persons for the supplier requests. The supplier request is a pre-step to a supplier, which is used to facilitate that suppliers are created in a systematic way and to avoid that duplicates or unwanted suppliers are added to the system.
Note that you can see and edit the information for the main contact person both from the supplier request header and from the line in the Involved Parties tab.
As a result of this activity, a contact person is added to the supplier request and will be used as the contact person when the request is converted to a prospect/supplier. The first contact added to the request will be set as main contact. You can change the main to another contact if needed.
