I am creating new custom field on user record. The value for the new field is based on the Username field on the user record, but only the text left of the @ sign. For example if Username is john.doe@company.com. The value for the new field should be john.doe. BTW, the right side is not alway "@company.com". If it was I could use - SUBSTITUTE(Username, "@company.com", ""). It could also be something like "@company2.com". Thanks.
