Multiple supplier records can have the same email domain after removing the unique constraint from the `Email Domain` column of the Supplier Email Domain \[sn_slm_email_domain\] table.

## Before you begin

Role required: admin  
Important:  
This procedure is required only for the upgrade scenarios (for all earlier versions upgrading to the Xanadu December 2024 release).

## Procedure

1. In the navigation filter, enter sn_slm_email_domain_list.do.
2. Hover and right-click Email Domain field to open the Dictionary Entry of `sn_slm_email_domain` table.  
3. Select the form context menu icon (![]()) and select ConfigureForm Layout.
4. From the Available list of fields, select the Unique field and move it to the Selected column.
5. Select Save.  
   The Unique field is now available in the Dictionary of the `sn_slm_email_domain` table.
6. Navigate to the Dictionary of `sn_slm_email_domain` table, clear the Unique check box and save the form.  
   Note:  
   If you are still unable to invite a supplier contact with duplicate domain, or if the onboarding playbook is stuck while waiting to send out an email to the supplier contact, follow the troubleshooting steps in the KB article [KB1709872](https://support.servicenow.com/kb?sys_kb_id=43cccf6483ca9a10cdbbc430feaad3d4&id=kb_article_view).
