Schedule Due dates are used to track changes to a buy after a specific date. The dates can be defined in Estimate Definition and/or in Market Goals Entry. If there is a schedule due date defined for an estimate and/or market, a record is made of the "original" buy as of that day and any spots added or deleted after that date show on reports as added or deleted.
To track changes separately for different broadcast date ranges in a buy, define separate Schedule Due Dates for each date range. For example, if you enter a buy for the entire year, you may enter separate Schedule Due dates for each quarter. See Multiple Schedule Due Dates for more information.
Several reports, such as the Buy Detail Report, the Post-Buy Market Detail Report, and the Post-Buy Product Detail Report use this information to compare the buy as it existed on the schedule due date to the buy as it exists when a report is run. This also allows you to track activity on a pool buy. On the Buy Detail Report, click the Print Adjustment Line check box to see the effects of changes after the schedule due date. Changes are shown under the corresponding week as +/- next to the number of spots each week.
Makegoods are not considered part of the original number of spots.
You may delete a Schedule Due date at any time, but you may not change it to be earlier than the system date.
If you change this date from a past date to a future date the current buy information overwrites the previous "original" buy information, thus making the current buy the "original" buy. The date change cannot be completed if any buy record is in use. In that case, a list of users accessing the buy data displays and you may continue to retry the process until it can be completed.
