Creating Multi-Level Work Breakdown Structure BOMs 

Use

You can use existing assemblies, create a multi-level work breakdown structure BOM for each individual production lot or you can use one multi-level work breakdown structure BOM for several production lots of a material.

Prerequisites

You have Created Production Lots and maintained the necessary control data during the creation.

Features

If you use an existing assembly, the multi-level WBS BOM automatically adopts the components. In the component overview, you also have the option of copying additional material or WBS BOMs and attaching them to a BOM item.

The components of a newly created multi-level WBS BOM are not adopted by the BOM of the assembly normally used due to its planning characteristics.

There are two different views which you can choose to create multi-level WBS BOMs:

All components in the individual BOMs are displayed.

All components of the product are displayed in a structure according to their role in production.

If you copy an assembly that already exists in the WBS BOM and attach it to another item, the assembly is aggregated and displayed in the Structure Overview, in order to avoid redundancy.

Activities

  1. In order to create a multi-level work breakdown structure, starting from the bills of material menu, you choose: Bill of material ® WBS BOM ® Multi-level maintenance ® Create.

    2. The initial screen appears.

  2. Enter the necessary data, like, for example, the WBS element (production lot number), the material and the application for the material.

    3. Choose Enter. The multi-level component overview appears.

  3. You can insert items for your BOM as follows:

Header materials cannot own a Sibling (same level node) but the lowest item can be maintained as header material and therefore can have Child (sub-level node).

Save your data.

To change or display the multi-level work breakdown structure BOM, starting from the Bills of material menu, you choose: Bill of material ® WBS BOM ® Multi-level maintenance ® Change or Display.

If you would like to delete an assembly, check whether it is used for other items. This assembly will otherwise be deleted for all items.
