How does Name Object decide how to create Salutations?
By default, Name Object will attempt to create a salutation in the order of Formal, Informal, First Last, Slug. If the required name components are present, that salutation will be created, but in the event one of the components is absent, the next salutation format will be used. For example, using the default order, for a name John, a formal salutation can not be created due to lack of last name, so the next format informal – since it does not require a last name. Likewise, a record with blank name data will cause the format to fall through to the slug format.
