Global Settings - Forecasting
A method of applying a configuration parameter at the system level. Global settings can be used to do the following:
• Enable or disable features
• Define limits and boundaries to sets of data
• Control parameters used during processing
These are a few of the more common global settings that apply to the Forecasting module. Contact your Technical Support representative for assistance configuring global settings in your installation of Servigistics.
DEMAND_DETAIL_AGGREGATION_BY_SLICE 
Description
Default Value
How Used
Defines how Demand Detail will be aggregated.
• When set to true the aggregation is one record per slice
• When set to false the aggregation is one record per day
false
• The DEMAND_DETAIL_AGGREGATION_SLICES global setting
• The DEMAND_DETAIL_AGGREGATION_MODE global setting
• The AutoPilot Demand Detail Aggregation process
DEMAND_DETAIL_AGGREGATION_MODE 
Description
Default Value
How Used
Defines the method to be used for aggregation. Options are:
• P — Partial
◦ Updates the values and inserts new records for the number of history slices defined by the DEMAND_DETAIL_AGGREGATION_SLICES global setting
◦ Honors column locks and preserves overrides
• F — Full
◦ Deletes rows with no matching detail
◦ Updates the values for the number of history slices defined by the DEMAND_DETAIL_AGGREGATION_SLICES global setting
◦ Honors column locks and preserves values only in locked columns
• T — Truncate
◦ Completely truncates and reloads the history records
◦ Column locking is not honored
◦ Does not respect the number of history slices defined by the DEMAND_DETAIL_AGGREGATION_SLICES global setting
• W — Time Window
◦ Completely truncates and reloads the demand history for the history slices defined by the DEMAND_DETAIL_AGGREGATION_SLICES global setting.
P
• The DEMAND_DETAIL_AGGREGATION_BY_SLICE global setting
• The DEMAND_DETAIL_AGGREGATION_SLICES global setting
• The AutoPilot Demand Detail Aggregation process
DEMAND_DETAIL_AGGREGATION_SLICES 
Description
Default Value
How Used
Defines the number of history slices from the present to include in the demand aggregation. This global setting is used by the DEMAND_DETAIL_AGGREGATION_MODE global setting when set to P, F, or W.
When this is set to 0, Demand Detail is not rolled up to Demand History
12
• The DEMAND_DETAIL_AGGREGATION_BY_SLICE global setting
• The DEMAND_DETAIL_AGGREGATION_MODE global setting
• The AutoPilot Demand Detail Aggregation process
EXP_SMOOTHING_HIST_AVG_BASE 
Description
Default Value
How Used
Specifies how the base forecast is initialized for the Single Exponential Smoothing and Double Exponential Smoothing forecast methods.
• When set to true, the history average is used to initialize the base forecast. This will generate more consistent forecasts over time.
• When set to false, the first slice is used to initialize the base forecast
• Set to true for new installs
• Set to false for upgrades
WINTERS_VERSION 
Description
Default Value
How Used
Defines the calculation processing for the Winters Multiplicative Forecast Method
Option
Description
1
Do not consider Alpha, Beta, and Gamma
2
Consider Alpha, Beta, and Gamma
3
Consider Alpha, Beta, and Gamma, and use the full year in the # of History Slices to calculate Winters Multiplicative Forecast Method
