# How do I change my email address or username in my supplier account?

## Symptom

- I need to update the username or email address for my supplier user account.
- My username or email address is incorrect.
- Who can update my supplier account username or email address?

## Environment

SAP Business Network

## Resolution

1. After accessing the account, click **\[User Initials\]** in the upper-right corner
2. Select **My Account**
3. Update the Email Address or Username field as needed
4. Check if there are any pending fields for completion
5. If any, please fill in the required information
6. Click **Save**

If your account is on Business Network on BTP:

1. After accessing the account, click **\[User Initials\]** in the upper-right corner
2. Click **Settings**
3. Under **User Preferences** click **User Account**
4. On the right side click **Edit**
5. Check if there are any pending fields for completion
6. Update the Email Address or Username field as needed as needed
7. **Save**

**Important:** do not change the Username when an active Sourcing connection exists in SAP Ariba Proposals and questionnaires. Changing the username might disconnect buyer relationships and causes error :[https://support.ariba.com/item/view/KB0395917](https://support.ariba.com/item/view/KB0395917)[Your company or user account does not exist on \[buyer\] site. \[buyer\] may have disabled the automatic synchronization of additional users from your organization, or there may have been an error when synchronizing your Ariba Commerce Cloud account with \[buyer\] site](https://support.ariba.com/item/view/KB0395917).

If no one has access to the account or its email address anymore, you must contact our [SAP Ariba Help Center](https://help.sap.com/) to proceed with the [account reassignment](https://me.sap.com/notes/KB0394475) request.

- If you changed the data on the **Email Address** field, you will receive a link at your current email address to confirm the update of the account’s primary email.
