Inventory and Sourcing

Inventory Domain A domain which includes all features related to stock accounting (how many items do we have at all, how many available, where etc.) and stock brokering (eq. from where we should allocate stock for the order placed in Spain, etc.).
SKU (Stock Keeping Unit) Distinct items, such as a products or services, offered for sale which embody all attributes associated with the item and that distinguish it from all other items.
A SKU is a unique, alphanumeric identifier that is used to track inventory. It should not contain spaces and must not exceed 64 characters in length. A SKU longer than 64 characters will cause an import to fail.
Pick List The grouping of order items which will be picked together, used both within a warehouse of store during the process of picking a customers order.
Sourcing Action of deciding at which source each of the lines of an order will be (hard) allocated.
Allocation queue All orders that are still pending to be assigned to a specific source. They could be new orders or orders that needs to be resourced. The Source Engine will process all lines in Soft allocation at the scheduled time to define a source in order to make an HARD allocation. The page will display flagged the exceptions.
Source An entity which represents a physical place where stock can be stored and where orders get dispatched from. Source has unique ID, name, address, a flag which tells if this source provides pickup service or no (is pickup location) and some basic setting for sourcing rules (when source can receive the new batch of orders).
Stock An entity which represent a stock level of the item (SKU) in a Source.
Stock-snapshot Sends a single message for a specific source for intra-day updates. If you have a very large catalog we recommend sending stock-snapshot updates in batches. There are three modes to send a stock-snapshot: DELTA, FULL or NONZERO.
Adjustment Frequent intra-day adjustments, or updates, that adjust the relative stock to the available quantity already in your OMS. Available stock is then recalculated to be sold for the modified SKUs and exported as a DELTA stock-snapshot message.
Stock aggregate An entity which represent the sale channel and is used to provide the stock levels to the external sales channel. Each stock aggregate can have one or multiple sources associated and will aggregate the stock available to sell for all the associated sources (calculating safety stock and in-flight orders).
Store Stock An entity which represent an aggregated Stock Keeping Unit (SKU) available in Stock aggregate.
Safety stock Is a specific quantity that can be defined at source, category or stock level of the item (SKU) level. The safety stock is decreased from the available to sell stock to provide a buffer against over-sales.
Sourcing Exceptions Exceptions rules can be configured in the configuration system. Orders that have at least 1 exception will be flagged and highlighted in the allocation queue so that the business manager can review in timely manner and provide some manual resolution to the exception. If no manual action is taken, during the next Source Engine run the order will be processed again.
Allocation attempt Every time an order line Soft Allocated is processed by the Source Engine is marked as allocation attempt even if the line couldn’t be hard allocated for some reason (no stock available, conflict with the business rules). The only case that won’t indicate an allocation attempt is for orders in a store that don’t have any source enabled in the specific allocation run.
Re-Source The action to push back an order line which is already hard allocated to the source engine so that can be sourced from a different source.
Sourcing scheduler / sourcing waves A method of running order sourcing which improves allocation efficiency by optimising orders into groups of orders sharing common SKU’s. The timeframes are configurable and each source can be enabled/disabled for a particular schedule. This method of allocation has benefits over FIFO (first-in, first-out) based scheduling and can be mixed with realtime sourcing for optimum allocation.
Soft allocation Soft allocation is executed for each physical line of the order as soon as the order has been imported in the Magento OMS. It’s the mechanism that will prevent the merchant to oversell in the various sales channels.
- Soft allocation is executed as soon as the order arrives in OMS or potentially during checkout (e.g. before running any fraud, remorse time etc.)
- Soft allocation will keep track of all orders inflight that are still pending to be assigned to a specific source node.
- Soft allocated items are decreased from the stock available to sell when generating a stock-snapshot to any of the sales channel.
Hard allocation Booking the stock at source level and implies the creation of a shipment request (either for the warehouse or the store picklist). It is done at line level so potentially would generate a split shipment if the same order is hard allocated to various sources.
- Hard allocation will override soft allocations (i.e. order lines with allocations won’t have a soft allocation).
- Hard allocation will be changed to soft allocation in case there is a pick decline or LSP out of stock cancellation and order line need to be re-sourced.
- Hard allocations can be manually forced from the Source Bucket or the Hot Bucket.
ATS (Stock) Available To Sell at the moment the information is provided with stock snapshot feed (which can be full or non-zero).
ATP Available To Promise Inventory as provided to front-ends.
PO Purchase Order
Harmonized Tariff Code International standardized system of names and numbers for classifying traded products developed and maintained by the World Customs Organization (WCO).
EAN 13 Wikipedia Definition: “An EAN-13 barcode (originally European Article Number, but now renamed International Article Number) is a 13 digit (12 data and 1 check) barcoding standard which is a superset of the original 12-digit Universal Product Code (UPC) system developed in the United States. The EAN-13 barcode is defined by the standards organization GS1.
All the numbers encoded in UPC and EAN barcodes are known as Global Trade Item Numbers (GTIN), and they can be encoded in other GS1 barcodes.”
GTIM Global Trade Item Numbers (see also EAN 13 and UPC).


Logistics Domain A domain which includes all features related to the process of pick, pack and deliver products to a customer (where deliver order from and to, how to deliver, what to deliver, track what delivered and when and so on).
Fulfillment The process of managing customer shipments.
Shipment A shipment is a record of the products in an order that have been shipped. More than one shipment can be associated with a single order.
Split shipment Part of the order which is ship at a different time or from a different location of another part of the order.
Package A parcel that is used to deliver the order.
Partial Shipment An order is partially shipped when part of it is cancelled (E.g. case when the inventory is damaged).
Shipment Request A request to the source to initiate order dispatching. Normally this request also means that source have to allocate stock for the item. Shipment request includes a unique number within the order, list of the items which need to be shipped and destination address.
Shipping carrier A company that transports packages. Common carriers include UPS, FedEx, DHL, and USPS.
Advice note Document that lists all products shipped to a customer. The advice note may not include prices for instance if the order is a gift and can’t then be considered as a formal customer invoice.
PUL (Pick Up Location) A Source which has a pickup location flag set, representing a place where a customer can pick up their order. An orders Pickup location is defined in the magento.sales.order message, from a frontend where customer has interface to choose where he wants to pick up an order.
Customer Pick up Confirm An event when customer is coming to the Pickup Location and picking up his or her order.
Currently the Pickup Location is likely to be a physical store, this is the most common scenario in retail today. In the future this concept may be expanded to include other locations, such as a gate in an airport, another retailer or commercial premise being used as a “collection point”, or in the case of some carriers it could also be a physical location specifically used for the delivery too and collection of parcels, for example DHL Pack Station.
There is an API endpoint for notifying OMS about this event.
Customer Pick up Decline An event when customer is coming to the Pickup Location and decline to pick up one or all items of his order.
There is an API endpoint for notifying OMS about this event.
Pick Confirm An event when runner is getting item from the shelf and put it to the customer package.

Order An order is a request for goods.
Order status The order status indicates where it is in the order cycle. In Magento, the system order status values are the following:
- Pending - Pending orders are brand new orders that have not been processed. Typically, these orders need to be invoiced and shipped.
- On Hold - The user cannot proceed to order processing if the order is in this state. This is convenient if, for example, some data must be verified.
- Payment Review - As long as an external payment gateway is verifying the payment information from a sales order, the order is assigned the Payment Review status both in the payment system and in Magento.
- Processing - Processing means that the order has been either invoiced or shipped, but not both.
- Complete - Orders marked as complete have fully been invoiced and have shipped.
- Cancelled - The order can be of this status if the customer calls your web store and asks to cancel an order if the order has not been paid for.
The store administrator can create custom order statuses, assign them to order states and set default status values for order states.
Purchase order (PO) A written sales contract between a buyer and seller that describes the merchandise or service to be purchased from a vendor.
Back Order An order that cannot be currently filled or shipped, but is requested nonetheless for when the item becomes available again. The backorder can be either planned or unplanned but in all cases the customer will be informed of the waiting period. If the backordered item is part of an order with other items, the available items will be shipped and only the line in backorder will stay onhold until the stock is available.
Pre-order Any order that has an item which is not currently in stock but has a fixed date in the future where the item is expected to be in stock.
Exchange An order line that exchanged for another product. The action is always initiated by the customer service and implies that the original item is returned to the warehouse and such return won’t generate a refund.
Reshipments For purchased item that was never received by the customer, or is received damaged the customer service will be able to request a new shipment of the item free of charge for the customer.
Appeasement Is the action to grant some kind of discount, gift, return,… to an unsatisfied customer. It is initiated by the customer service team and could be in a form of a promocode to be applied on future purchases or a partial refund on his order. The merchant would have defined with the customer service team what are the limits and rules to apply an appeasement to his customers.
Appeasement refund Refers to a partial refund executed against an order line (can be against an item, a service or the shipping cost). This is manually initiated by the customer service agent.


API An Application Programming Interface is a software interface that lets third-party applications read and write to a system using programming language constructs or statements. This means, it specifies how some software components should interact with each other.


Back Office The web based application which users can login to in order to monitor process within OMS.

Launch and Deploy

Development complete All of the testing phases that follow below assume that development is complete by all work streams. We assume here that unit testing and functional testing would already have been taking place. Even testing specific interfaces with third parties would have also taken place.
SIT System Integration Test. All development environments are able to talk to each other and exchange data. Dependencies are important to manage to ensure no section of the entire system is stopped. We should expect here that end-to-end testing can take place. Some parts of the system might be in MOCK modes (e.g. Payments are not connected to Banks, Logistics are not picking and packing and sending products).
UAT User Acceptance Test. Client tests in Staging.
MTP All code moved to production. Another piece of testing should take place in each functional area to ensure features are functioning correctly. Production credentials configuration for connecting to 3rd party systems etc. should take place.
Basically smoke testing all of the connectivity and configuration to get ready for end-to-end testing which will take place in Soft Launch.
Soft Launch All Systems in production connected. End-to-end (e2e) test can be performed. Stores are NOT open to the public (employees of Magento and client only).
No parts of the system in MOCK modes (e.g. Payments are connected to Banks with real credit cards being used, Logistics are picking and packing and sending products). Actual returns are taking place.
Hard Launch Open to the public. Launching with the maximum customer experience, although some items could have been excluded to be able to meet a launch date.
Examples could be something like refunds… an important customer experience, but not at day1 of launch. Refunds and returns could be deferred to a subsequent release to production, say 1 week later.


COO The Country of Origin is the country of manufacture, production, or growth where an article or product comes from. There are differing rules of origin under various national laws and international treaties.
PIM Product Information System
RRP Recommended Retail Price
UPC The Universal Product Code is a barcode widely used in the United States, Canada, the United Kingdom, Australia and New Zealand and in other countries for tracking trade items in stores. Its most common form, the UPC-A, consists of 12 numerical digits, which are uniquely assigned to each trade item. Along with the related EAN barcode, the UPC is the barcode mainly used for scanning of trade items.
