Assumption periods
An assumption period is a defined timeframe to set time-dependent assumptions for forecasting. If during a forecast period you need to update these assumptions, you can create a new assumption period. From the start date of this new assumption period, your revised assumptions will take effect. When you create a new assumption period (see Adding assumption periods), the assumptions you made previously are assigned to the period before the start date of the new assumption period.

What are the different origins of a time-dependent data field?
When editing a time-dependent data field, you might come across some icons that indicate the origin of the data. This is what they stand for:
• A blue value indicates that the value is inherited (and possibly indexed) from a previous assumption period:
• A blue clock value indicates that the value is inherited (and possibly indexed) from a previous assumption period and that there is a manual input in a future assumption period:
• A black clock value indicates that there is a manual input in a future assumption period:
