I receive the error message below when trying to register a new user account.

Error: User already exists. Please enter a different username.

You are receiving this message because the username you are entering is already associated with an SAP Business Network, SAP Business Network Discovery, or Ariba Sourcing supplier account. You will still be able to register a new user account, but the new username will need to be unique to satisfy system requirements.

如果收到错误消息用户已存在。请输入其他用户名。，我该怎么办？如果我看到一条消息，说明我的用户名当前已被使用，我是否还可以注册？

您之所以收到该消息是因为所输入的用户名已关联 Ariba Network、Ariba Discovery 或 Ariba Sourcing 供应商帐户。您仍可以注册新的用户帐户，但需要确保新用户名唯一，以满足 Ariba 系统的要求。

SAP Ariba 要求所有用户名的格式与电子邮件地址相同，但不需要是有效的电子邮件地址。例如，假设您不能使用 example@ariba.com 作为用户名，请尝试使用 example1@ariba.com。

如果想要访问已存在的帐户，请前往供应商登录页面并单击密码。

If you would like to access an account that already exists, go to the supplier Login page and click Password.
