Change event dates in the external schedule
If the program WBS data was already exported to the external schedule from Teamcenter, and you must change event dates or program start date, you should change the dates in the external schedule.
After changing the dates of events in the external schedule, send the updated information back to Teamcenter. This action updates the corresponding events' planned dates in Teamcenter. If the contract schedule was already generated, the system automatically updates the dates of the corresponding tasks.
If the event tasks are referenced in any DRI event table, you must reschedule the impacted DRIs, as follows:
Procedure
Select one or more DRIs in the DRIs for Reschedule panel, and choose Reschedule Data Requirement Items.
The Reschedule Data Requirement Items panel is displayed.
Update the schedules of the selected DRIs and then click Reschedule.
