Demand Configuration
Introduction
Forecast calculations in 4C Supply® can be provided forecast configuration parameters. These parameters are forecast calculation inputs, thus become part of the forecast calculation report and are displayed at a high level in the forecast overview.
Forecast calculation parameters can be set
in the scenario specification,
on the forecast calculation page or
as a mix of both.
If forecast calculation parameters are set in the scenario specification, they are
evaluated during specification interpretation and
displayed on the forecast calculation page as defined in the specification and as read only.

Column Definitions
Computation Interval
Computation and report intervals may be defined either from the Calculation page or a Demand Configuration specification table.
The computation interval can be set between 1 and 7 days. A computation interval of 1 will generate forecasts precise to one day by running a longer, more complex calculation. For most forecasting requirements the default interval of 7 days will provide sufficient detail and produce results more quickly.
See forecast configuration section for more information.
Report Interval
The Report Interval is the interval used in all Output Reports. In the Demand Configuration Table in the SMART Editor, a value of 1 Day or 1 Month (Default) can be entered. In the Demand Configuration Tab on the Calculation page, users will select 1 Day or 1 Month from the drop down.
Manual overage
Overage which is manually added to the forecasted root node demand to define the production quantity
production quantity = manual overage x forecasted root node demand + forecasted root node demand
Accepts decimal values (e.g. 0.5) and percentage values (e.g. 50%). If a non-valid entry is made, an input validation error message is shown.
Valid range: 0% - 100%. If an out-of-range value is entered, an input validation error with the following message is shown:
Enter value between 0-100
Manual overage is included as root node demand in production plan validation and can therefore cause out of stock errors which aren’t reflected in the inventory projection because it doesn't represent any subordinate depot demand.
Manual overage is expected to lead to residual stock at the root node because there is no corresponding subordinate depot demand.
Manual overage impacts the forecasted total scrap, but is not the same parameter.
Enrollment level
Enrollment can be set to Site or Region. If left blank, the default is Site.
If the enrollment level is set to site, the 4C Supply® specification interpreter will evaluate specified enrollment rates as patients per site per month.
If the enrollment level is set to region, the 4C Supply® specification interpreter will evaluate enrollment rates as patients per region per month.
See Enrollment, section enrollment levels.
Confidence used for site buffers
See forecast configuration, section confidence used for site buffers.
Accepts decimal values (e.g. 0.5) and percentage values (e.g. 50%).
If an invalid entry is made, an error message is shown:
For site buffer confidence, expected a percentage or a float but found ERROR. Ignoring.
Valid range: As shown on the site confidence dial on the forecast calculation page.
If an invalid entry is made, an error message is shown:
The value specified for confidence used for site buffers is out of range. Range is [defined notch value range], but found [value as entered]. Ignoring.
