 <p>This is a glue module for the sale line position on the delivery report
 and the module <cite>stock_picking_group_by_partner_by_carrier</cite>.</p>
 <p>It ensures that on the delivery report the position column is displayed
 only if some positions exist.
 And also adds the sale line position on the remaining to deliver list at
 the bottom of the report.</p>
