Salesforce Validation rule on Lead Conversion
I am sharing a video for the validation rule to fire on lead conversion. Creating a Validation Rule, where a Mobile, Fax & Website fields must not be blank when convering a lead.
Also make sure, if you like to fire the validaiton rule/workflow actions/apex trigger, then make sure to enable the “Require Validation for Converted Leads” option under the Setup -> Lead Settings.
