We are using SIPM for onboarding new and existing suppliers. How can we incorporate our native Vendor ID into the Ariba Supplier Workspace. Is there an additional field that we are not aware of that is available for this purpose?

We are aware of the Ariba ANID which is the supplier's Cloud Profile record.  We are also aware of the Organization ID.  Are there any other fields that we can reserve and then use to import our suppliers into the Supplier Workspace?
