   The saved search provided by the Dunning Letters SuiteApp is selected by default. This predefined
   saved search contains a list of customers of invoices that have been assigned a dunning
   procedure. You can use your own saved search, but you must make sure that your saved search
   does not have any customer, invoice or invoice group that does not have a dunning procedure.

   selecting a frequency, you must define a start date, end date, execution time, and additional
   schedule details.
