Purchase planning

The purchase planning process for clustered items is identical to that of the nonclustered items, because these items share item purchase business partner information. Only the supply strategy can be defined separately for a clustered item. However, to select suppliers based on the cluster (local purchasing), you can use the warehouse on the Ship-from role of the business partner.

If you entered a particular warehouse cluster for a supplier, that supplier can only deliver goods to this warehouse. As a result, the purchase planning process takes that supplier into account only when a plan item passes to a cluster for which the default warehouse equals the warehouse on the Ship-from role.

Example

The item is for 70 percent supplied to cluster 2 by means of distribution from the central production site. However, the cluster also purchases the same item locally (30 percent of supply). A sourcing strategy is defined for this item. You can also purchase the item centrally from another supplier. You can model this with the following setup:

In the Items - Planning (cprpd1100m000) session, specify the following fields:

Setup for local purchasing (Plan items)
Field	Nonclustered item	Clustered item
Plan Item	JOSCOM	USA JOSCOM
Cluster	(None)	USA
Default Supply Source	Production/Purchase	Distribution
Default Warehouse	DUB (Dublin)	NY (New York)

In the Ship-from Business Partner (tccom4121s000) session, which you can access from the Business Partners (tccom4500m000) session, specify the following fields:

Field	Supplier for USA	Supplier for nonclustered warehouse
Setup for local purchasing (Suppliers)
Supplier	SUP000002	SUP000003
Warehouse	NY (New York)	DUB (Dublin)

According to these settings, supplier SUP000002 can only deliver to the cluster and warehouse in New York.

Supplier SUP000003 only delivers to the warehouse in Dublin.

If a sales order is accepted in the New York sales office, the planning run automatically includes only the suppliers that have the New York warehouse connected, and suppliers that do not have any warehouse connected.

In this case, the planning run takes only SUP000002 into account to plan the clustered item USA_JOSCOM. The planning run selects clustered warehouse NY for the planned purchase order. You can transfer the planned purchase orders to the purchase department.

The goods are then received on the clustered warehouse.
