When trying to create a new account through an invitation email sent by the buyer or self-registration from the Supplier Registration Portal, below warning message appears:

We found existing accounts based on the information you entered. Please review.

When registering a new account on SAP Business Network, the system automatically checks for:

• Company name
• Company email domain
• DUNS number
• Other identifiers linked to your company

If matches are found, you’ll get a warning message like:

We found existing accounts matching your company details. Please review them before proceeding.

To check for accounts you or someone in your company may have already registered, follow these steps:

1. Click Review accounts on the pop-up warning message.
   
   
2. Review the matched account. You can view the details of each account from Top recommendations and Other existing accounts list.
   

• If you find an existing account that you want to use, click Contact administrator to send a message to the account administrator requesting access. Then click Send email.
  Once the administrator of the existing account adds you as a user, you will be able to log in through the invitation using that account.
  
  
• If none of the displayed accounts are relevant, click Back > Continue account creation to create a new account. Once the account is created and you have signed in, you will be linked to the buyer and any documents / events they have sent you.

• The email to the account administrator will be sent from ordersender-prod@ansmtp.ariba.com
• SAP cannot provide specific account information, such as email address or administrator details, the best way to find out who registered other existing accounts is to send an email to administrator directly via Contact administrator button.
