An Overview: LPN & Shortcuts to Mobile Telnet (Part-I)

License Plate Numbers (LPN’s) are an easy method to use to accurately perform inventory transactions in WMS. They are also very user friendly and help save time. In the two part series blog I will discuss LPN, its usage and useful shortcut keys for Mobile Telnet, commonly known as Putty. Click here to read Part 2

In the two part series blog I will discuss License Plate Numbers (LPN), its usage and useful shortcut keys for Mobile Telnet, commonly known as Putty. In my first blog I will introduce LPN. Let’s begin with:

What is LPN?

LPN in Oracle Warehouse Management (WMS) is an identity assigned to a group of items represented systematically, that travel through the Unit/Floor together. The LPN will help identify a group of items packed together in terms of its current subinventory, location, revision, lot, serial, organization and item contents.

Uses of LPN:

Using LPN’s in WMS we can perform the following tasks:

  • Store delivery related information such as its content items, revision, lot, serial, organization, sub inventory, or locator
  • Track contents of any container in receiving, inventory, or in-transit
  • Receive, store, and pick material by LPN
  • View on hand balances by LPN
  • Move multiple items in a transaction by LPN
  • Transfer LPN contents
  • Pack, unpack, consolidate, split, and update LPNs
  • Print labels and reports for referencing container contents
  • Reuse empty LPNs
  • Receive and send LPN information on an ASN 

Types of Transactions available in WMS related to LPN:

  • Pack Transaction- As the name suggests the Pack transaction enables the business to pack loose material into an LPN.
  • Consolidate Transaction- this enables the business to nest a child LPN inside a parent LPN.
  • Unpack Transaction- this enables the business to unpack either material or a nested LPN from a parent LPN.
  • Split Transaction- this is essentially an Unpack and Pack combined together, creating a new LPN with some material from another LPN.
  • Update LPN Transaction- The Update LPN transaction enables the users to update the weight, volume, and container item of an LPN. As in all other transactions, LPN transactions of lot, serial, or revision controlled material requires you to enter the item controls. 

LPN Context/Status Code:

1 - Resides in Inventory

This particular context code indicates that material associated with this LPN has been costed and accounted for in an inventory. A LPN with this context may not be used when receiving material against a standard or inspection routed receipt, but may be used during a direct delivery routed receipt. However, outbound transactions can be performed on LPNs with this context.

2 - Resides in WIP

The context code indicates that material associated with this LPN is currently being transacted in WIP (Work in Process). Therefore, the associated material is not yet in inventory and has not been costed to inventory.

3 - Resides in Receiving

The context code indicates that material associated with this LPN have been received using a standard routing or inspection routing receipt and have not been delivered or put away yet. Therefore, the associated material is not yet in inventory and has not been costed to inventory.

4 - Issued out of Stores

LPNs in this status are no longer tracked by the system, and hence, no longer associated with a locator within the warehouse. LPNs shipped out of inventory receive this context and may not be re-received.

5 - Defined but not used or Pre-generated

LPN in this status means they are not associated with any physical material. They can be printed and used to identify material during any stage of the material management process such as inbound, replenishment, outbound, and so on. This context refers to LPNs that are ready to be used.

6 – In-transit

As the name suggests, LPN in this context is an indication that it is currently moving from one location to another. Possible uses for this are when a LPN is moved from one organization to the next, for example while the LPN is on a Vehicle/in transit. This context is particularly used for Internal Sales Orders (ISO) or Inter-org transit where an indirect shipping network is defined between the organizations.

7 - At Vendor

This context comes into picture when a vendor sends an Advanced Shipment Notice (ASN) to Oracle WMS, the system internally generates LPNs and associates them with material information on the ASN. These LPNs receive this context. Material associated with LPNs of this context are not on-hand or costed until it is actually received.

8 - Packing context

This context is primarily used for setup of picking or put away rules, basically this status is temporary and used internally by the software as an intermediary.

9 - Loaded to Dock/ Shipments

An LPN loaded for shipment has just been loaded onto a carrier ready to leave the warehouse. Once the entire carrier leaves the dock, the LPN obtains a context of six Resides in in transit or four Issued out of stores.

10 - Prepack for WIP

This context value is used when the system has associated the LPN with material and printed the labels, but the material has not yet been physically packed.

11 – Picked

In Particular when LPN’s are picked they are assigned with a context value 11. They are in-transit within the warehouse.

How to view LPN’s

LPN can be viewed using both mobile user interface & through application using Material Workbench.

In the Material Workbench, you can view the attributes of a particular LPN. Use the following instructions to view the contents of an LPN.

  1. Navigate to the Material Workbench window.
  • In the View By field, select LPN from the list of values.
  • Next is to expand the Organizations folder to display list of LPNs for the organization.
  • Select the LPN that you want to view.
  • The system displays the contents of the LPN in the right panel of the window. You can also expand an LPN in the left column to view its specific contents.

     Viewing LPNs with the Mobile User Interface:

    • Log in to the mobile user interface under the Whse Mgmt responsibility.
    • Select Inquiry from the Whse Mgmt menu.
    • Select the LPN option from the Inquiry menu.
    • Next step is to enter the LPN or select it from the list of values, In the LPN field.

    Generating License Plate Numbers:

    LPNs can be generated using one of the following methods:

    • Submitting a concurrent request:

    For submitting the LPN generation request, you must select the Generate License Plates option from the Oracle Warehouse Management Navigator. In a single concurrent request we can generate multiple LPNs. Each generated LPNs can be printed on stickers and accordingly as and when required it can be associated with a particular container item, or they could be simply labeled with no physical container association. They can be generated at the sub-inventory and locator, or they could have no location until they are packed.

    LPN generation request generates the quantified number of LPNs based on the starting prefix, suffix, and start number specified either in the request, or at the organization level. Labels for these LPNs will be printed accordingly, based on you label printing software and hardware.

    Using a Mobile Device to Generate LPNs:

    Using the Mobile Receipt & Task form LPN’s can be generated in Putty/Telnet. When the cursor is in the LPN field, press Generate to automatically generate the LPN. The system default shortcut key, for Generate is [CTRL]+[G].


    LPN’s are an easy method to use to accurately perform inventory transactions in WMS. They are also very user friendly and help save time. In the second part of the article we’ll learn more about generating LPN’s using mobile interface and different types of transactions associated with LPN’s.
