This window contains:
Flow ID: The identifier for the forecast set associated with the part. Note also that a part may be associated with more than one flow.
Flow Description: The description of the forecast set.
Part No: The forecast part number. Note that a part being forecasted through Demand Planning need not be an inventory part in the IFS Application.

Use this window to view and modify forecast part parameters.
N/A
This window contains:
In the Inherited Historical Demand group box:
Predecessor: The name of the forecast part's predecessor. The predecessor is used when aggregating inherited demand.
Predecessor Description: The description of the predecessor.
Inheritance: The state of the inheritance flag (this can only be turned on/off from the demand plan client).
Start Date: The date to start inheriting demand from the specified predecessor.
End Date: The date to stop inheriting demand from the specified predecessor.
In the Flow Info group box:
Flow Description: The name of the flow.
Flow Type: The flow type, base or combined.
Site: The site associated with the flow.
Site Description: The description of the site.
In the Market Info group box:
Is Market Segment: Whether the part is a market segment part and thus a market segment (Yes) or not (No). See Market Segment.
Fixed Market Share: Whether this part has fixed market share. See Market Segment.
Market Segment: The market segment that is connected to this part number. See Market Segment.
Market Segment Description: The market segment connected to this part's description . See Market Segment.
In the Authorized Internal group box:
Phase In: The phase in date for the part. The user is not allowed to set any forecast quantity for the part, before the period witch contains this date. E.g. If using monthly period version and phase in date is 01.12.2003, the the user is not allowed to enter a forecast for the part in the periods before December 2003 (2003-12). See Authorize Intervals. Note that setting this date only affects the ability to set values in the Adjusted forecast.
Phase Out: The phase out date for the part. The user is not allowed to set any forecast quantity for the part, after the period witch contains this date. E.g. If using monthly period version and phase out date is 01.12.2004, the the user is not allowed to enter a forecast for the part in the periods after December 2004 (2004-12). See Authorize Intervals. Note that setting this date only affects the ability to set values in the Adjusted forecast.
In the Part Info group box:
Aggregation Type: The forecast part's current aggregation type. There are 3 options:
- Incremental - This can be used only by a forecast part that already has aggregated historical demand. When an aggregation is performed in this state, only the historical demand for the last period (the missing period) is aggregated.
- Recalculate Historical Demand - The aggregation is done by reaggregating all historical demand from the start and then setting the aggregation type to Incremental.
- Delete Forecast Data - First, the budget, events, target sales plan, and the historical forecasts are deleted. Then, the historical demand is reaggregated and the historical forecast is set equal to the forecast made using the current forecast model. Finally, the aggregation type is set to Incremental.
Part Classification: The forecast part's classification the field is read only. There are 11 classes:
- No Classification - All parts that never have been classified are set to this ID.
- New Parts - New parts is all parts that have under 1 year and 2 periods of historical demand. This is a fixed number. If months is used as the period length then all parts that have less than 14 periods are treated as a new part.
- Intermittent - Intermittent parts are determined by counting the number of zeros in the series. If the number of zeros is higher than the IntermittientZeroPercent limit then the series is intermittent. The IntermittentZeroPercent can be changed from the registry key: HKEY_LOCAL_MACHINE\SOFTWARE\IFS\ForecastServer\Classification\ IntermittientZeroPercent.The default value is 20. Which means that all parts with 12*0,3=3,6=4 zero periods or more per year are set as intermittent, when a monthly period version is assumed.
- Season - A part that is intermittent, and also has a season. For season detection procedure see Season Profiles (Season Component Detection Algorithm).
- Level - A part that only has level. You can go here for information about the level detection procedure.
- Level/Season - A part that has level and season. For season detection procedure see Season Profiles (Season Component Detection Algorithm)
- Level/Trend(+) - A part that only has a positive trend. You can go here for information about the trend detection procedure.
- Level/Trend(-) - A part that only has a negative trend. You can go here for information about the trend detection procedure.
- Level/Trend(+)/Season - A part that only has positive trend and season. You can go here for information about the trend detection procedure. For season detection procedure see Season Profiles (Season Component Detection Algorithm)
- Level/Trend(-)/Season - A part that only has negative trend and season. You can go here for information about the trend detection procedure. For season detection procedure see Season Profiles (Season Component Detection Algorithm)
- Terminated - No transactions of the part have occurred for a specified number of periods. You can go here to get more information about terminated parts.
Note that you can have a hierarchy of market segments (one market segment can be a market segment of another market segment). However, be careful when using this functionality because it can become complicated to use and understand.
