Before supplier users can access any of the collaboration network applications, a user account needs to be provided to them. Typically, user account creation is a function that system administrators perform, but the Supplier User Management(available in Supplier User Administrator/Supplier User Manegment responsibility)  feature allows designated users within the buying organization to create and manage external user accounts. These designated users can register new supplier user accounts and update user details to alter the supplier users profile and access rights.

•  
• Supplier User Management allows the buying teams to respond directly to the suppliers whom they are dealing with on a daily basis rather than having to process account requests through their IT department. Supplier User Management is only used to create and manage external accounts; it is not used to access and manage internal employee accounts.
•  
• The registration process within Supplier User Management is the only way supplier user accounts are created. This ensures that the supplier user’s account is designated as external and is directly linked to the supplier with whom the user is associated. Supplier users can no longer be created from the User form in the regular Oracle eBusiness Suite.
• Supplier user accounts are only created for suppliers that are defined in the purchasing system.
