Assemblies with a Long Replenishment Lead Time 

Purpose

It is often necessary to obtain an assembly with a long replenishment lead-time before the design of the entire product is completed.

In the turbine T-20000 you require an extra coolant pump. You have to start early with the production of the pump so that it is available on time. However, the design of the entire turbine is not yet complete. You can not yet decide at which point you are going to integrate the second pump in the multi-level BOM for the sales order item.

Process Flow

You have already created the sales order.

  1. You create an order BOM for a material that is not yet included in the multi-level BOM for the sales order item.

    2. This type of assembly is referred to as a Detached order assembly.

  2. You generate preliminary requirements for the detached order assembly.

When you execute a requirements planning run for the material of the sales order item, only the assemblies that exist in the multi-level BOM are included. If a detached order assembly has a long replenishment lead time, it may be necessary to generate requirements even before the design of the entire product is completed

You have the following options:

See: Material Requirements Planning for Detached Order Assemblies

See: BOM Transfer to Project System

  1. You execute a planning run.

The system generates planned orders, which you can convert into production orders.

  1. You continue with designing the whole product.

In the order analysis of the order browser, you have an overview of all detached order assemblies for a sales order item. During the design process you decide at which point to insert the detached order assembly into the multi-level BOM.

  1. You include the header material of the detached order assembly as an item in an assembly in the multi-level BOM for the sales order item.

This causes the detached order assembly to become integrated in the multi-level BOM.
