The following steps are required to enable M2M mapping. ## Procedimento 1. Create and run a fix script to enable M2M mapping. For detailed steps, see [Run the fix script to enable M2M mapping](https://servicenow-prod.fluidtopics.net/4ohL1872Yj5cCSdoLorHcw "Run the fix script to enable M2M mapping between supplier contact and suppliers."). 2. Verify that the version record is created for the script `include M2MSupplierSupportUtil`. For detailed steps, see [Verify version record](https://servicenow-prod.fluidtopics.net/D~yOZzIJbr~iYzefeMPAlw "After the fix script is created and run to enable M2M mapping between supplier contact and suppliers, a version record must be created."). 3. Configure the Supplier Email Domain \[sn_slm_email_domain\] table to remove the `unique` constraint from the `Email Domains` column. For detailed steps, see [Remove the unique constraint from Email Domain](https://servicenow-prod.fluidtopics.net/ZwCTeUnXAov1DxslIep02w "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.").
