FROM/TO - this allows you to view all work items which are between two particular milestones according to their progress in the standardization process. For example, all work items which are between 'Start of OAP' and 'End of OAP'. The search can be further refined by selecting a start and finish date for the query. This will only show WIs where either the achieved date or target date (planned) for the selected milestone range falls between the dates selected.
