Working with Material BOMs in the Validation Phase

Objective

After completing this lesson, you will be able to work with material BOMs in the validation phase

Material BOM Validation

Group BOM ↔ Plant-Specific BOM

You can create a BOM without reference to a plant in the form of a group BOM. This is useful when an engineer is working with a BOM during the engineering phase, but does not know yet which plant it is used in. The group BOM can later be converted to a production-relevant, plant-specific BOM. To do this, you can either assign a plant or create a copy of the BOM.

The image depicts a plant assignment process for a material T-FL00 within a group. The material has an internal number 4711 and is used in both engineering and production. Initially, the material is assigned at the group level for engineering usage. From there, two options are shown: copying the assignment unchanged to plant 1010 for engineering use (internal number 4711), or copying and changing the assignment to plant 1010 for production use with a new internal number 4712. This illustrates how a material can be assigned and tracked differently based on whether it is used for engineering or production purposes at a specific plant level.

To assign a plant, you simply add a plant to the group BOM. However, it is still the same BOM, with one internal BOM number. Therefore, when a group BOM is changed you see the changes in the plant-specific BOM.

A BOM copy is a second, separate BOM with a different internal BOM number. The group BOM only serves as a copy template.

You can select any direction for both plant assignments and copies.

Work with Material BOMs in the Validation Phase

Introduction: Work with Material BOMs in the Validation Phase

Until now, most of the data was created as plant-independent ones. BOM engineer Marc has now the task to extend the existing group BOM to a plant BOM, or copy the group BOM to a plant BOM. Marc then checks and extends this data.

Task 1: Copy the Group BOM to a Plant-Specific One

In this task, BOM engineer Marc copies the forklift group BOM to a plant-specific BOM in plant 1010. He familiarizes himself with the new information. He checks the header status or works with the assemblies.

Finally, he changes components like the Windows shelter.

Now, you have an impression of "Working with material BOMs in the validation phase".

Material BOM Evaluation

BOM Reporting Functions

Now that you have created a wide variety of bills of material (BOMs), you want to get an overview of them. A wide variety of applications are available for this purpose.

Explode Bills of Materials

In a BOM explosion, the components of a BOM are exploded either on a single level or on multiple levels. An explosion provides you with a useful overview of the required components and materials.

The where-used list displays where a material is used, and in what quantity. This is useful for determining the requirements for a particular material.

The BOM comparison is useful if several BOMs are created for one material, and different usages or change statuses are to be determined.

The app Explode Bills of Material allows you to display a multilevel BOM with detail information. A summarized BOM is also available inside this view.

Work with Material BOM Evaluations

Introduction: Work with Material BOM Evaluation

In previous tasks, BOM engineer Marc has worked with multilevel material BOMs. He was able to check the component status for every material BOM individually. Now, he is interested in multilevel evaluations.

Task 1: Perform a Level by Level Material BOM Explosion

In this task, BOM engineer Marc performs a level by level BOM explosion for his forklift prototype. He is also interested in the status information for every component on every level.

Task 2: Perform a Multilevel Material BOM Explosion

In the prior task, BOM engineer Marc performed a level by level BOM explosion. As the material BOM contains three low levels, Marc lost the overview and was unable to answer the question of which assembly belongs to which BOM. Therefore, he decides to test a different BOM explosion: a multilevel explosion.

Task 3: Perform a BOM Comparison

BOM engineer Marc first created a group BOM. Then, he used this group BOM as a template for the plant BOM. When this was done, he changed the plant BOM.

Now, he wants to know what differences exist between the group and plant BOM. Therefore, he starts a BOM comparison.

Now, you have an impression of "Working with material BOM evaluation".
