This field is the marketing name of the coverage. If a policy only can have one coverage, like many life policies in the USA, then this field would be the Plan Name for the policy. Advisors Assistant does not have a separate field for the Policy Plan.
The Coverage Plan Name of the Base Coverage would typically be the same as the Policy Plan that is used for marketing the policy.
In Advisors Assistant Version 2.8, this field was referred to as Series.
