Initialize, Roll, and Update Scenario (cprpd4200m000)

	Initialize, Roll, and Update Scenario (cprpd4200m000) Use this session to carry out the following actions: Initialize the scenario after changes in the plan period definition. Roll the scenario. Initialize the master plans for every new plan item. Related topics To update master-plan data Using a rolling scenario 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. Planner The employee or department responsible for planning the production, purchase and distribution of items. The planner takes into account the inventory levels, availability of materials, and capacities of resources, and reacts on signals such as rescheduling messages that LN generates. Channel A sales or distribution channel used to assign goods to customer groups. You can link channels to sold-to business partners and to items. Channels can be used in connection with available-to-promise (ATP). You can assign a certain ATP volume to a channel. This volume limits the ATP for that channel to a maximum. From Plan Item An item with the order system Planned. The production, distribution, or purchase of these items is planned in Enterprise Planning based on the forecast or the actual demand. You can plan these items by means of the following: Master-based planning, which is similar to master production scheduling techniques. Order-based planning, which is similar to material-requirements planning techniques. A combination of master-based planning and order-based planning. Plan items can be one of the following: An actual manufactured or purchased item. A product family. A basic model, that is, a defined product variant of a generic item. A group of similar plan items or families is called a product family. The items are aggregated to give a more general plan than the one devised for individual items. A code displayed by the item code's cluster segment shows that the plan item is a clustered item that is used for distribution planning. Update Goods Flow Data If this check box is selected, LN reads the goods flow data and the capacity utilization of orders from the execution level and aggregates this data in the aggregation relationships structure. If this check box is cleared, the scenario retains the current goods flow data. Note If the session rolls the scenario, this check box will automatically be selected. Related topics To update goods-flow data Multicompany Updating If this check box is selected, LN carries out a multicompany update. That means that LN updates each scenario in the multicompany structure of the specified scenario. Note You can only access this field if the scenario is a multicompany scenario. Related topics The use of centralized multicompany planning Generate Requirements If this check box is selected, LN generates material requirements and capacity requirements. The capacity utilization is also updated. LN generates these receipts and requirements on the basis of: The production plan The bill of critical material (BCM) The bill of Critical Capacity (BCC) Note The receipts and requirements are only updated for the selected plan items. For example, if the production of plan item A results in a material requirement for plan item L, and this session is run for plan items in the range A to K, the requirements for plan item L are not updated. The receipts and requirements generation overwrites the existing requirements and receipts. If this session rolls the scenario, this check box will automatically be selected. Related topics To update master-plan data Generating critical material requirements To generate critical capacity requirements Generate Item/Channel Master Plan If this check box is selected, LN generates an item master plan for the selected plan items, and a channel master plan if you linked channels to the plan items in the Plan Item - Channels (cpdsp5100m000) session. Note If the item already has an item master plan, this will be updated. Even when the check box is cleared. The session Initialize, Roll, and Update Scenario (cprpd4200m000) session is the only session that creates master plans. A plan item does not need to have a master plan. A plan item can have a master plan if the Master Plan check box in the Items - Planning (cprpd1100m000) session is selected. However, you can postpone the initialization of this master plan. Related topics Master planning, an overview Parallel Processing If this check box is selected, parallel processing is used to roll plans or initialize the plan. Related topics Bshells for Parallel Processing Generate Resource Master Plan If this check box is selected, LN creates a capacity overview for the resources you select. You can view these capacity overviews in the Resource Master Plan (cprmp3501m000) session. Note It is recommended to only create capacity overviews for the most important resources. These capacity overviews slow down the performance of your system. Resource A group of machines or employees in Enterprise Planning, corresponding to a work center in other LN packages. Each operation performed to manufacture an item requires a certain capacity amount from a resource (for example, production hours). The capacity of the resource can be a constraint in the planning. The availability of a resource can be specified by using the resource calendar. Resource A group of machines or employees in Enterprise Planning, corresponding to a work center in other LN packages. Each operation performed to manufacture an item requires a certain capacity amount from a resource (for example, production hours). The capacity of the resource can be a constraint in the planning. The availability of a resource can be specified by using the resource calendar. Initialize Only for Items Without Existing Plan If you selected the Generate Item/Channel Master Plan check box, you can select the Initialize Only for Items Without Existing Plan check box, if LN must only initialize the scenario that you selected for plan items that do not have an item master plan or a channel master plan yet. The Initialize Only for Items Without Existing Plan check box is implemented for performance reasons.
