Bill of Materials — Quantity-types

Kevin Updated by Kevin


This article is building upon the knowledge learned in the Bill of Materials article.
A Quantity-type BOM is defined as a BOM that has a Yields Quantity greater than one

With Quantity-type BOMs you can create Bill of Materials that allow you to:

  • Split a large Cases that contains smaller packs that are order-able
  • Split a Case into Singles
  • Chain BOMs to allow a large Case to be split into its sub-Cases that then can be split into Singles; allowing an Order to be fulfilled by picking the appropriate sizes
  • Products that Split a Case and then are reformed into several custom sized packs


You will want to consider a few things as you setup a Quantity-type BOM and how it will be used. i.e.:

  • Will you be keeping stock on the largest Case size
  • Are there in-between size Cases
  • Are alternate size packs needed
  • Can a Case be split
  • Can a Case be built

Products as different quantities e.g.: Peanut Butter as Singles and as 4-packs while only keeping stock on the 4-pack.

  • Stock could then be on the 4-pack but tell the System how to split the 4-pack into four Singles
  • Then when someone orders 6 Singles; the Picker would be told to pick it as one 4-pack and two Singles
BOMs are one directional, to create bi-directional relationships you will need to create a BOM for each direction. e.g.:
● The Singles can: "Split a Case to make 4 Singles"
● A Case can: "Build a Case from 4 Singles"

Ship Separately

When you need to have the Cases ship out separately there are a couple of extra steps that will need to be taken for Quantity-type Products. You will set the Case up as you would normally expect by setting in the Case Product's Packaging tab the fields Ship Separate to Yes and Max Per Package to 1. You will also need to go to the Singles SKU and set its Max Per Package field to the largest Case size. i.e.: If the Case is a pack of 12 we will want to set the Max Per Package to 12 on the Singles SKU.

Using Bill of Materials

When working with Quantity-type BOMs a few things are done a little differently. A Quantity-type BOM will effect both Deliveries and fulfilling Orders.


Quantity Type BOMs have a greater effect on Deliveries than do Kit Type BOMs. This is because Quantity-types are typically handling how Cases and Singles should relate to one another. Whereas Kit-types will most likely have its components delivered as components.

i.e.: A Case of Flashlights is delivered such that half the case is damaged. The good half will be scanned as Singles and put-away as 0.5 of a Case.

Deliveries should be made for the components, unless it is a Quantity-type BOM, then the Delivery Product should be the base item that is stocked. i.e.: Stocking the Product as the Case and not as the Singles.

When creating RMAs through the Receiving > RMAs grid remember that the Client/Purchaser may be sending back some Singles but the RMA should be made for the Product that has the stock. The quantity returned may be a fractional number of the Case if the amount being returned is not a full Case.

A clue when looking at Quantity-type Products that the returning items should be entered as the Product that has a quantity available.

Accepting a Delivery will not differ from normal.


Quantity-type BOMs will differ slightly, and even then it will only really differ when there is a need to process only part of a Case.

  • User will see a new sub-counter that will count the fractional quantities of a whole Case
  • The Fractional Counter can be incremented by scanning the Single's barcode or by clicking in the field and typing
  • The Fractional Counter will auto convert Singles into Cases when enough Singles are counted to equal a Case
  • The red "X" button on the Fractional Counter will clear the fractional number
  • The normal Counter buttons are the same, controlling the whole numbers in the large counter field

Example Showing the Fractional Counter counting to a whole Case

If there is damaged Product on a Quantity-type BOM, the User should process the undamaged Singles on the Case Product as a fractional count. The User should avoid adding the Singles to the ASN as an unexpected SKU.

During put-away only Quantity-type BOMs will look and behave differently. The counter for Quantity-type BOMs will work like the Counter for Processing. The User will put-away the Cases and Singles at the same time using the Counter and the Fractional Counter.

This is how it works if the Product is being stocked as Cases. If they are being stocked as Singles then the counter will look like normal and all Cases will need to be counted as Singles.


Quantity-type BOMs will effect how the inventory looks for the Product that the inventory is stored.

Product Inventory and Warehouse View


Orders for Quantity-type BOMs will look different depending on whether the Order is for the Singles and Stock is on the Cases or if the stock is on the Singles. In general stock would typically be kept on the largest Case SKU.


When Batching Quantity-types the only difference will be seeing fractions for the amount to pick, but the Picker will be given whole numbers to pick. i.e.: Pick one Case and two Singles.

When picking a Product with a Quantity-type BOM, the Picker will see an information box asking the user to be careful what they pick because there could be whole cases and opened cases.

Scanner UI Picking Quantity-type products warning

A Quantity-type BOM will be shown in Packing similar to how a Kit-type is show. The difference is that a Quantity-type BOM can be scanned as all Singles or as the Case and Singles depending on the quantity ordered. The Remaining column will decrease as either Cases or Singles are scanned.

When Blind Count is on, then only the Product and Packed columns will be visible.

Packing six Singles

Viewing Quantity-type Information on

Viewing Quantity-types on Orders will not be drastically changed.


The Order view will continue to show the exact Product that was ordered.

Order View ordered items section


However the Shipment view will show the Product that is used to hold the stock for the Ordered Item.

Order View Shipment items section


A completed Order for a Quantity-type BOM Product depending on how it is packed could take various forms in the Package details. Using the above examples the Package could show that it was packed out as six Singles or as one Case and two Singles.

Packaged as one Case and two Singles
Package Quantity-type as one Case and 2 Singles
Packaged as six Singles
Package Quantity-type as 6 Singles
