Many a times we need to treat Salesforce Standard Fields as required. To do this, we can create a validation rule for the field to ensure that a value is required to enter in there. Here are the steps (in this example, we're making “Phone” required):
- Go to Setup - Customize – Contacts
- Select Contact filed – “Phone”
- Create a validation rule
- Click Save.
