Supply source for clustered itemsA clustered plan item can be supplied by distribution, purchase, or production. You can also define multisourcing strategies. Distribution If the default supply source is Distribution, the plan item is replenished from warehouses in other plan clusters. To set up distribution planning (DRP), you must define supplying relationships between the planning clusters (warehouses) in the Supplying Relationships (cprpd7130m000) session. The DRP functionality uses these relationships to generate planned distribution orders to supply the planning cluster. Note You must define warehouse supplying relations on planning cluster level. You do not need supplying relationships on warehouse level, because Enterprise Planning always plans on the same default warehouse per planning cluster. Purchase If the actual supply source is Purchase, external suppliers supply the plan item. This setup is called local purchasing. To set up purchase planning, use these sessions: The planned cluster segment is only applicable in Enterprise Planning. Therefore, all the plan items use the same purchase data and item purchase business partner information. The supply strategy is optional and you can define a supply strategy for each cluster. This strategy determines the priority rules for the selection of suppliers during the planning run. Production If you set the default supply source to Production, production orders supply the clustered plan item. To set up production planning, the following sessions are the most important sessions:
The cluster segment is only used in Enterprise Planning. As a result, the clustered plan items use the nonclustered manufactured item’s BOM, routing, bill of critical material (BCM) and bill of critical capacities (BCC). In the order horizon, the planning routines use BOMs and routings to explode material requirements and operations. In the planning horizon, the planning routines use BCMs and BCCs to explode material requirements and operations. Multisourcing Clustered plan items can also have multiple sources of supply, such as a combination of distribution, purchase, and production. To define multisourcing, you can use the sourcing strategy. You can set up a separate sourcing strategy for each clustered plan item. To set up the sourcing strategy, use the Sourcing Strategy (cprpd7110m000) session: For distribution sourcing only, you can set up cluster-specific distribution relationships. This option is not available for purchase and production. Therefore, the planning process always uses the same item purchase business partner information and same BOMs and routings to plan both the nonclustered item and the clustered items. You can set up the high level sourcing strategy by cluster.
