Use the Import WBS Schedule Window to import new WBS schedule data from outside MPM. Optionally, you can also shift resources and/or milestones to new dates for WBS elements based on the imported dates.
Access the Import WBS Schedule Window by double-clicking the WBS Schedule icon on the Menu Manager with the Imports tab showing. MPM displays the Import WBS Schedule Window.
The WBS Schedule import file contains the WBS ID, Baseline, ETC, Early, and Late start and complete dates. If you do not select any of the conditioning options, MPM copies the Early and Late start and complete dates from the import file, inserts them into the WBS element's Early and Late dates, and ignores any Baseline or ETC dates included in the import file.
To specify the point in time where updating dates and shifting resources begins, enter the Time Now Date. MPM uses this optional field to determine whether to update the specified WBS elements. Only those WBS elements whose early start date is after the Time Now Date are updated. If you leave this field blank, all dates are updated.
To update the baseline dates in MPM, choose Update Baseline Dates From. This option determines which dates in the import file are used to update the Baseline dates.
Import — uses the baseline start and complete dates in the import file
Early — uses the early start and complete dates in the import file
Late — uses the late start and complete dates in the import file
MPM sets the baseline start and complete dates equal to the imported/early/late dates in the import file. If a WBS element has no resource estimates, its start date is set equal to the imported/early/late start date (whichever was selected), and the complete date is set equal to the imported/early/late finish date.
If a WBS element contains resource estimates, click the Shift Baseline
Resources 
check mark box to shift baseline resource
estimates from their planned start to the new start date. Further, because
the completion of a WBS element is determined by the length of its estimates,
only the start date will be set equal to the imported/early/late start
date; the duration of the estimate will be maintained.
To update the ETC dates in MPM, choose Update ETC Dates From. This option determines which dates in the import file are used to update the ETC dates.
Import — uses the ETC start and complete dates in the import file
Early — uses the early start and complete dates in the import file
Late — uses the late start and complete dates in the import file
MPM sets the ETC start and complete dates equal to the imported/early/late dates in the import file. If a WBS element has no resource estimates, its start date is set equal to the imported/early/late start date (whichever was selected), and the complete date is set equal to the imported/early/late finish date.
If a WBS element contains resource estimates, click the Shift ETC Resources
check mark box to shift ETC
resource estimates from their planned start to the new start date. Further,
because the completion of a WBS element is determined by the length of
its estimates, only the start date will be set equal to the imported/early/late
start date; the duration of the estimate will be maintained.
