The reports with the suffix '_L'
(and 'Lines' in the title) refer to the Product Lines sold by that
distribution channel. Distribution channels, whether wholesale
or retail, tend to sell a wide range of product lines, from
differing product groups or sectors, and thus if one's company
involved in distribution, as opposed to the production of goods or
the provision of services directly to the End User, then one should review
these Product Line titles.
