This field, in conjunction with other fields, governs which customer order lines of the selected order will be displayed in the "Available Lines " list box.
It serves the purpose to limit the number of lines to be displayed and will not display lines where the order line completion date (ship date) is a date later than the specified date. It defaults to 1 month in advance.
Should certain lines not appear in the list as expected, it might be required to select a later date for "Ship Dates Until" or the lines may already have been fully shipped or the order lines have not yet been set to a status of "Released".
