BOM Design


BOM is the basic input of Production Planning. Thanks to these schemes, information on the required quantities and supply times of the material to be used in the production of the product is kept, and the information on how long the product will be procured before it is produced is reached. 



BOM production is ongoing and also is the production planning of the developing products, together with the connection diagrams under the product and part stock. Reminiscent of a tree, this diagram is more like a roadmap.

BOM is a diagram showing the product manufacturing process from the raw material at the lowest tier to the final product at the top tier. Bill of Materials (BOM), shows which material and how many units are used to produce the product being produced.

By creating a BOM for the products produced with Workcube BOM Design; standard consumption amounts of products, production/labor times, and waste materials are effectively managed. Alternative materials to consumables can be defined and configured.

In this way, the delivery time of the product is determined.

What Can You Do With BOM Design?


With Workcube's unique spec approach, it can easily create an unlimited number of BOMs for each product. With Spec, there is no need to repeatedly create a BOM from scratch for each different variant of products.

In particular, organizations that manufacture to order can create different BOMs, specifications, without changing the standard bill of materials for each order by using the spec.

In this way, instead of keeping a separate BOM and inventory code for each different version of the product, the spec of the product is created in a shorter time and in a simpler way. In this way, the main and intermediate additives in production can be easily tracked.

  • Create an unlimited number of bills of materials
  • Detailed tracking and filtering of BOMs
  • Viewing BOMs, listing by category
  • Direct transition from product management to bill of materials and production processes
  • Revising BOMs, adding, removing, and modifying operations
  • Listing the designed BOMs, saving in Word, Excel, Pdf format, and sending e-mail
  • Ability to add products from inventories for the bill of materials, create specs
  • Possibility to list the products according to their specs, print them and follow the production stages



How to Save BOMs to the System?


Before a bill of materials is registered to the system, all consumables, raw materials, semi-finished products, and the product itself to be used in the bill of materials must be defined in the system. Products are defined in the system from the products page.

Route: ERP > Sales-Distribution > Products and Inventories > Products

For each operation performed during production, operations must be defined in the system. Each operation is recorded in the system from the Operations page.

Route:  ERP > Production > Production Design > Operations

Afterward, each work center where the product will be produced must be defined in the system with the Work centers page.

Route:  ERP > Production > Production Design > Work Centers

Note: In order to define a product's bill of materials, the "On Production" box must be ticked on the product definition screen. However, when this box is checked, the link to the screens required for the creation of the BOM will be opened in the menu.



After checking the On Production box, relevant definitions can be made by going to the BOM page.

Route: Product Card > Other > BOM


Warning: Before defining a bill of materials for a product, it is recommended to define the BOM of semi-finished products, which are the input of that product, into the system. In other words, the design should be made hierarchically from the lower semi-finished products to the upper main product.


Approach: Displayed only in the BOM that is the master. BOMs created according to variations are formed according to the approach determined in the master BOM.

Quantity Type: It can be determined as Quantity and %Proportionately. According to the selected filter, a BOM is created in the Add Component field and BOM components according to Quantity or ratio.

While creating the BOM, the required raw materials, consumable quantities, operations, waste materials, and specs are selected one by one in the add component section and added to the BOM at the bottom by clicking the "Add Component" button.

Process: It is the area where the materials to be used in production are added to the product tree by selecting which operations they will go through.

Component Type: Choose the component type from here.

Product: It is the area where the raw materials, consumables, and semi-finished products to be used in the production of the product are selected and added to the BOM.

Spec: Choose Spec.

Transaction: This is the field in which the order in which materials and operations will be added to the BOM is defined.

Line: Fill here for the line.

Quantity: This is the field where the quantities of the materials and raw materials to be added to the bill of materials are determined according to the main unit in their product card. eg. When 5 is entered here for the fabric raw material, the system adds the 5 meter fabric to the BOM over the unit defined in the Fabric product card, "Meter". The data type of the amount field may change according to the amount type determined in the approach in the box above.

Size: Put the info about size.

Question: If the raw material added to the bill of materials is a configurable component, the question to be asked to select that component is determined from this field. For detailed information, you can read the "Product Configurations" document.

Material Loss Quantity: This is the field where the amount of waste from the material is defined.

Material Loss Rate: This is the area where the percentage of the material is lost.

Explanation: You can write an explanation here.

Combine at Shipping: If this option is checked for a material added to the BOM, this material will not be spent when production is finalized. So it is not deducted from inventory. For example, if you want the screws used in production to be deducted from inventory during shipment, not during production, you must add them by ticking the "Combine at Shipping" box when adding screws to the BOM. Combine on shipping option can also be defined from the screen on the update icon on the far right of the product after the product is added to the BOM. When this box is checked, the product appears as spent only after the product is shipped with a delivery note and is deducted from the inventory.

In the BOMs, the sequence starts from zero. If processing will be applied to a material; the sequence number of the material and the operation must be the same.

For example,in the production of a Mixed Pickle, the "Wash" process will be applied to Cabbage, Gherkin Cucumber, Garlic, and Pepper, so the order of all of them is selected the same.


Alternative Products: With this icon, Alternative Product can be defined based on Alternative Questions.


Delete Product: With this icon, previously defined products and operations in the BOM can be deleted.


Product Structure (BOM): With this icon, the order, quantity, waste material amount, waste rate, and alternative question selection of the materials/operations in the BOM can be edited.


Work Center: With this icon, the work centers of the operations of the BOM can be arranged. Work Center add-delete-update operations can be done.


Sub-BOM: It is necessary to create a separate BOM for each product (semi-finished product) included in the BOM. The BOMs of these products can be accessed directly with the help of this icon. When semi-products are added to the BOM, the pre-defined BOM for that semi-product is automatically added into the main BOM.

Note: After each edit made in the BOM, the Save button must be clicked. Otherwise, the changes will not be saved.


Inventories - BOM by Variation

A product can have multiple inventory codes and different variations. According to the alternative questions determined while creating the master bill of materials, alternative question selections can be made while creating the BOMs of the sub-variation inventories, and a variation bill of materials can be created.

Variations listed with the red tree icon in the list are variations for which a bill of materials has not yet been created. When the "Create BOMs by Variations" button is clicked, only BOMs of variants for which BOM has not been created can be created.


Note: BOMs of variations are created according to the alternative questions of the master BOM. In other words, BOMs of variation inventories cannot be created without creating a master bill of materials.

This is the screen that appears when the "Create BOMs by Variations" button is clicked. Alternative bill of materials can be created by defining alternative questions determined in the master bill of materials. Columns such as Which Color Product, What Size Information, Which Packaging come from alternative questions pre-determined in the master BOM.

We see that from the alternative questions Which Packaging and Which Color product options make inventory selection. The Alternative question, "What is the Size information" allows manual data entry. The reason for this depends on the "Alternative Transaction" Type specified when creating an Alternative question. Definitions such as "Change stock" or "Change Size" in the alternative question definition affect these areas.

Note: When creating a BOM according to variations, if it is saved as it is without any changes, a new BOM is created exactly the same as the master BOM.

What is the Phantom BOM?


Phantom Bill of Material is a method applied when it is not desired to follow up the production and inventory of semi-finished products in a Bill of Materials.

It is applied by defining the "Don't create component order for this product" parameter in the lines of the manufactured products (semi-finished products) in the bill of materials. When a production order is placed for a product that contains a phantom bill of materials:

  • A production order does not occur for a phantom product.
  • The consumables of the phantom BOM are reflected in the production of the parent product to which the phantom product is connected, and when the production of that product is finalized, the inventory transactions of the components in the phantom product are realized.

Note: The fact that phantom BOMs do not appear in the material requirement calculation works depending on the XML of the material page. In order for the "Don't create component order for this product" checkbox to be active, go to Page Settings and select "Use Phantom BOM" as Yes.

At the same time, the consumables of the Phantom BOM are reflected in the first manufactured product to which the Phantom Product is attached. In order for Phantom BOMs not to appear in Material Requirement Calculation, the Page Settings settings of the material page must be adjusted.
