// Gets an entity list iterator of product requirements by vendor.
// This report requires a two-level query:  one subquery to merge the
// requirements with the same productId (grouped by partyId), another
// to count the products required by the partyId.  This is modeled with two
// view entitities chained together, RequirementByPartyCount and
// ProductRequirementCount (see order entitymodel_view.xml).
