Microsoft Dynamics NAV

Bill of Materials

In Microsoft Dynamics NAV you can create such type of a product which is called a bill of materials (BOM). It refers to the complex component structure, basically this is the list of materials or components which is used to build the final product and from which this product actually consists. For example, a customer is looking for a computer and he or she wants to see the list of hardware the computer consists of. The ERP system can store a lot of different spare parts that are used to manufacture a product which are actually not intended to sell. These spare parts can be also a part of the complex product structure.

In the Sana webshop a customer can see a link View package contents on the product details page of a BOM. Clicking on this link opens the list of BOM components.

Create a BOM in Microsoft Dynamics NAV

Step 1: Open an item card and click: Related Information > Item > Assembly List > Bill of Materials.

Step 2: Enter information to identify the BOM (Type, No., Quantity, Unit of Measure).

Step 3: Use the Visible in Webshop checkbox to show or hide any BOM component in the Sana webshop.

You can also show and hide a bill of materials in the Sana webshop just like a regular item. On the item card of the BOM, on the E-Commerce FastTab, use the Visible in Webshop checkbox to show or hide the BOM item in the Sana webshop. If you make the BOM item invisible, its components will remain visible in the webshop as separate items.

Assembly policy

 NOTE

The Assembly Policy feature is available in Microsoft Dynamics NAV 2013 and higher.

In Microsoft Dynamics NAV open the item card of the bill of materials. On the Replenishment FastTab you will see the field Assembly Policy.

Using the field Assembly Policy, you can change the way how stock should be calculated for the BOM item.

Select one of the following options:

• Assemble-to-Order - Stock is calculated based on all available BOM components. The system checks how many finished products can be produced from the available BOM components. When a customer purchases the BOM item, stock will be deducted from all BOM components. Use this option for items that you do not want to stock because you expect to customize them to customer requests or because you want to minimize the inventory carrying cost.
  
  For example, you are selling bicycles and you allow your customers to purchase different components of it, so they can assemble a custom bicycle - wheels, bicycle frames and seats, pedals, etc.
• • If there are 2 wheels, 1 bicycle frame, 1 seat and 2 pedals in the warehouse, then a customer will be able to assemble 1 bicycle. Thus, the stock is 1.
  • If there are 4 wheels, 2 bicycle frames, 2 seats and 4 pedals in the warehouse, then the stock will be 2, because it is possible to assemble 2 bicycles from these components.
  • If there are 4 wheels, 1 bicycle frame, 2 seats and 4 pedals in the warehouse, then the stock will be still 1, because 1 bicycle frame is missing, and it is not possible to assemble 2 bicycles without it.
    
    
• Assemble-to-Stock - Stock is calculated for the main BOM item as for one saleable unit. This means that the BOM item with all its components is a finished product. When a customer purchases the BOM item, stock will be deducted from it as from one saleable unit, but not from its components. Use this option for items that you want to assemble ahead of sales and keep in stock until they are ordered. This is the default option.
