Providing an Expression to Calculate a Custom Field's Default Value

When a new row is created for an object, the value of a custom field defaults to null unless you configure a default value for it.

You can supply a literal default value of appropriate type or supply an expression to calculate the default value for new rows. The default value expression is evaluated at the time the new row is created. The expected return type of your field's default value expression must be compatible with the field's type (Number, Date, Text, etc.)

For example, consider a custom CallbackDate field in a TroubleTicket object. If you want the callback back for a new trouble ticket to default to 3 days after it was created, then you can provide a default expression of:

CreationDate + 3
