Scenarios (cprpd4100m000)

Use this session to maintain scenarios.

Note

If you have started this session by zooming, you can only find and select a record.

 

Scenario

The identification of an overall planning solution.

Each scenario represents one overall planning solution, and involves particular settings for the planning of items and resources. You can use scenarios to analyze and compare various planning options and to find the best planning solution. For example, you can vary demand forecasts or sourcing strategies.

One of the scenarios is the actual scenario, which corresponds with the actual planning situation. You can only transfer planned orders and production plans from the actual scenario to the execution level of LN.

If the Scenario Status field has the value Closed, you can no longer modify any data in this scenario.

General
Scenario Start/Finish Date

The period a scenario.

If you change the start or finish date, it does not immediately take effect. The changes are effected when the master plan is updated by means of the Initialize, Roll, and Update Scenario (cprpd4200m000) session.

The value of the Scenario Start Date field also determines the availability of historic demand data for the generation of a demand forecast.

Performance aspects

The setting of this field could affect system performance and database growth. For more information, refer to Scenario start and finish date.

Scenario Status

An indication of whether the data in a scenario can still be changed.

The plan status can be Open or Closed.

When a scenario has the Closed plan status, you can no longer modify it.

Update Pegging Relations during Order Planning

This field determines whether LN must update the pegging relations if you execute an order-based planning run.

Allowed values

  • Always
    Each time you execute an order-based planning run, LN also updates the pegging relations.
  • Never
    If you execute an order-based planning run, LN does not update the pegging relations.
  • User Specified
    If you execute an order-based planning run, LN updates the planning relations only if you select the Update Pegging Relations check box in the Generate Order Planning (cprrp1210m000) session or the Generate Order Planning (Item) (cprrp1220m000) session.
Alternative Materials Horizon

The time period for which LN tries to find an alternative material if a standard material is not available.

The alternative materials horizon is expressed as a number of working days from the date you carry out the order-planning process. LN rounds the horizon to the end of a plan period.

Important!

The value of this field must not exceed the value of the CTP Horizon field in the Items - Planning (cprpd1100m000) session for any plan item used as alternative material. Otherwise, LN erroneously assumes that the alternative material is infinitely available to cover for shortages of the standard material.

This horizon is not applicable to use-up material. LN checks for use-up materials for the entire order horizon.

Days

The date on which LN sets the alternative materials horizon.

To find the correct date, LN starts from the current date, and counts forward the number of workdays that you entered in the Alternative Materials Horizon field. LN then rounds the date up to the end of that plan period.

Rolling Data
Rolling Scenario

If this check box is selected, the scenario is a rolling plan.

Reference Date

A date that determines when a rolling scenario is shifted forward in time.

Example
Reference dateJanuary 5
Rolling frequency14 days

 

On or after January 19, the scenario is shifted forward 14 days. The new reference date will be January 19.

Rolling Frequency

The number of days after which a rolling scenario is shifted forward in time.

The number of days by which a plan is shifted forward equals the value of the scenario's rolling frequency.

Note that the rolling frequency is defined in calendar days.

Example

If the rolling frequency is seven days, the scenario will be shifted forward seven days, every seventh day.

Central Multi Site Planning

If this check box is selected, the scenario is a multisite scenario. You can use multisite scenarios to coordinate a number of local scenarios.

If this check box is cleared, the scenario applies to a single logistic company.

Note

If the Central Multi Site Planning check box has been cleared, you can still perform some sort of multisite planning. See The use of decentralized multisite planning

Scenario Text

If this check box is selected, a text is present.

Related topics

Actual Scenario

The scenario that contains the operational master plan or order plan, as opposed to scenarios used only for simulation, that is, what-if analysis.

The actual scenario is the only scenario from which you can transfer planned orders to the execution level.

Forecast
Include Sales Quotations

If this check box is selected, LN adds the sales quotations to the customer orders in the master plan.

Note

LN only takes the quotations with a high chance of success into account. See To add quotations to customer orders.

Minimum Days for Forecast

The minimum number of days that must be available for a plan item in the demand history to calculate a demand forecast with the Generate Demand and Inventory Plan (cpdsp1210m000) session.

Forecast Period Length

The period length that is used in the generation of the demand forecast in the Generate Demand and Inventory Plan (cpdsp1210m000) session.

Backward Forecast Consumption

The number of calendar days preceding the delivery date of customer orders during which the demand forecast can be consumed by those orders (including dependent demand).

If an item has an item master plan, the demand forecast for the plan period in which the planned or actual delivery dates of a customer order fall is always consumed, regardless of the value entered in this field.

If an item does not have an item master plan, the demand forecast for the day in which the planned or actual delivery dates of a customer order fall is always consumed, regardless of the value entered in this field.

Note

If an item has an item master plan and the limit for forecast consumption is halfway a plan period, LN uses the entire period for forecast consumption.

Forward Forecast Consumption

Indicates the number of calendar days following the delivery date of customer orders that the demand forecast may be consumed by those orders (including dependent demand).

If an item has an item master plan, the demand forecast for the plan period in which the planned or actual delivery dates of a customer order fall is always consumed, regardless of the value entered in this field.

If an item does not have an item master plan, the demand forecast for the day in which the planned or actual delivery dates of a customer order fall is always consumed, regardless of the value entered in this field.

Note

If the limit for forecast consumption is halfway a plan period, LN uses the entire period for forecast consumption.
