Unit of Measures (UOM) Functionality

Modified on Tue, 5 Dec, 2023 at 9:16 PM

What is UOM?

The UOM (Units of Measure) feature, enables the management of relationships between Outer Cartons, Packets(or Inner cartons), and Eaches(or Individual items) for any product, thereby allowing Carton-in and Piece-out functionality.

Item master setup:

While creating a new item, the user will need to activate the “Add UOM info” toggle. This opens a new section “UOM info” to add the details at each UOM level. The steps for this process are as follows:

  1. Select the UOM level i.e. outer carton or inner carton.

  1. Input the Barcode of that UOM and then enter its immediate child barcode into the "Child Barcode" field.

  2. Multiplier is the total number of eaches in a carton. (Eg. If an outer carton contains 5 inner cartons, and each of these inner cartons holds 10 individual units, the multiplier will be 50 for the outer carton and 10 for the inner carton)

  3. Proceed to input the remaining dimensions and weight details for that particular UOM level.

  4. Click on the “Plus” button if there are more levels of UOM and similarly fill the details for the inner carton.




Note: Let’s consider that the barcodes for the outer carton will have a suffix “_M” and that for the inner carton will be “_P”. 
For example: A SKU has the barcode “SKU123”, then the barcode at each corresponding UOM level will be as follows:

  • Outer Carton: SKU123_M

  • Inner Carton: SKU123_P

  • Eaches: SKU123


Inward Flow

1. Purchase Order:

The Purchase Order Quantity will always be in eaches only.The creation of PO follows a standard procedure similar to any normal product.


2. GRN:

The GRN is processed on the UOM level corresponding to the products received at the warehouse. The steps for this are as follows:

  1. Scan the barcode of the Outer Carton/Inner Carton/Eaches as per the material received.

  2. On scanning a carton, a pop-up will appear asking the Pack Size. 


  1. To proceed to the next steps, it's necessary to input the correct Pack size here (i.e. the actual pack size must match the Pack Size specified in the Items Master)

  2. Once the correct pack size is entered, the user has to enter the Quantity of the carton.



  1. Meanwhile, the GRN of eaches(individual units) follows a standard procedure similar to any regular product as shown below.

  1. At any given time, the GRN progress against the PO can be checked, displaying the GRN completed at each level.

  2. Submit the “Complete GRN” button once completed.


3. Putaway:

  1. Once the GRN is completed, a putaway will be created against the GRN.

  2. There are no changes in the Putaway Process. The steps are: Scan the Bin > Scan the Carton/eaches > Enter the Quantity.


At any point of time, the putaway progress can be checked at the bottom of the page. This section indicates the pending putaway status at each of the UOM levels.

Note: A single bin can have multiple UOM items (unless their batch is different). 



Inventory Management:

  1. The inventory level of any SKU can be checked by navigating to Inventory > All Inventory. This tab displays the inventory of any SKU at the eaches(individual item) level.


  1. To view the inventory at all the UOM levels for a product, navigate to Inventory > Inventory Locations. Click on the (+) button against any SKU and the inventory across UOM level present in a bin will be visible as shown below.

  2. The Bulk Break of cartons can be initiated at this page by clicking on the “Break Carton” button as shown below.

    On clicking the Bulk break button a following pop-up appears asking the number of cartons needed to be broken.

Outward Flow:


Note: The Order will always come into the system in eaches only.


The outbound order can have 2 scenarios: 

(i) The order can be fulfilled without needing to break any carton. This scenario is automatically prioritized by the WMS and the picklist is generated accordingly.
(ii) The order requires breaking an outer or inner carton to fulfill the order. This can be handled through the “Bulk Break” feature. 

Scenario 1: No Bulk Break

Picking: The Picklist indicates the number of cartons or eaches required to be picked to fulfill the order as shown below.


Packing: The packing process for individual items follows a conventional sequence: Open the box, add items, and then close the box.
Meanwhile, cartons can be packed directly within the system by clicking the 'Pack Carton' button and scanning their barcode as shown below.



A packing slip is generated for this carton accordingly indicating the number of units in that carton.




Bulk Break

The bulk break is used when the order processing requires breaking the carton. 
The bulk break activity can also be initiated separately from the outward order processing. It can be initiated by navigating to Inventory > Location Inventory .


The bulk break activity involves initially breaking the outer carton, followed by generating barcodes for the smaller UOMs and affixing the stickers to them.


The step by step process for the bulk break activity is as follows:

1. Navigate to Inventory > Bulk Break. It shows a list of all the Bulk-break requests created in the system along with their current status.

2. Click on the “play” icon to start the bulk break activity.


3. Scan the bin and the carton which needs to be broken as shown below.

4. Enter the correct pack size and generate barcodes for the smaller UOMs, then affix the  stickers onto them.


5. Now scan the smaller UOMs, scan the bin again and click on “ADD” to break a carton. 


6. This process decreases the inventory count of outer cartons by 1 and adjusts the quantity of inner cartons accordingly.

7. Repeat this process for breaking each carton individually. Then, click on 'Complete'.
