LN only updates the channel master plans that you specified in the Plan Item - Channels (cpdsp5100m000) session. Procedure This session carries out the following steps: Roll the scenario If the scenario is a rolling plan, and a certain number of days passed since the reference date, the plan is shifted forward in time. See To use a rolling scenario. Update the master plan LN updates the master plan of each selected plan item. See To update master-plan data. Note If a scenario is rolled forward, LN updates all plan items, regardless of what range of plan items is specified. Note If you specify a Scenario Finish Date for your scenario that does not match the end of the last plan period, the length of this last plan period is not equal to the plan period length you defined in the Scenario - Periods (cprpd4120m000) session. This leads to disproportionate planning values if you roll the scenario with the Initialize, Roll, and Update Scenario (cprpd4200m000) session.
