Can I combine the multiple ANIDs (Ariba Network ID) I have registered on Ariba ?

Users made several registrations on the Ariba.

You cannot combine the ANIDs. However, you have the option to contact the buyer and request to link with the ANID account that you want to use.
After all buyer users are linked to just one account, the other accounts can be deleted/deactivated.

When you choose to link buyer users to just one account and excluding the other ANIDs, please note that all data for the deleted account will be lost.
