It is important for the SBB registration invitation to be sent to the same e-mail address as the one your existing SAP Ariba account works with. If you do not already have an Ariba account, it must be the e-mail address you also want to use for your account. We recommend using a general address. If you would like to change the e-mail address for your invitation retrospectively, please send an e-mail to dp2go@sbb.chLink opens in new window..
