Extract Miscellaneous Fields From The Eligibility Rules

During this step, you extract miscellaneous fields that must be captured on the order in order to drive the eligibility rules.

The following table illustrates a miscellaneous field which is captured on the order to drive the eligibility rules:
Misc. Field	Where Stored	Why Is It Needed
Date of birth	Person characteristic	Numerous eligibility rules use this field to determine if a customer is a senior citizen

Note: Fields explicitly referenced on every order. You'll notice that we didn't list those fields referenced in the eligibility rules that are explicitly referenced on every order (e.g., customer class, state, division, etc.). This is because these types of fields come "for free".
