Currently all you have available on Sales Orders is Promised Date. The issue is that we have performance metrics with most of our big customers. And if we just ship on the Promised Date the parts run the risk of being late because of transit time. So we need to have other external methods to try and calculate on what day to ship so that we meet the on dock requirements.
No one "promises" anything anymore. Not even ECI uses "promised date" on their own paperwork to us. It should read "estimated ship date".
