| Plan periods in Enterprise Planning |  |
| A scenario consists of plan periods. Plan periods can be of varying length, and are defined in calendar days, weeks, or months. You can define the plan periods for a scenario in the Scenario - Periods (cprpd4120m000) session. After this, you need to run the Initialize, Roll, and Update Scenario (cprpd4200m000) session for the changes to take effect. Note If the plan-period definition does not cover the whole scenario, ERP LN extends the last plan period to cover the remainder of the scenario. Plan periods are used as time buckets for master planning. Note In Enterprise Planning, horizons and time fences are rounded to the end of a plan period, except for the signal horizon. For that reason, you must always define plan periods for a scenario, even if you only use order planning. Related topics Scenarios in Enterprise Planning Horizons and time fences |
