Item Management

Item Management

Overview

Workday item management includes the purchase item and supplier item used to purchase goods and services. Purchase items serve as the master item in Workday. The purchase item stores crucial information used throughout Workday Spend Management to drive functionality and business processes. This includes identifying characteristics like item identifiers, descriptions, item image, item tags, and item groups. The purchase item also stores key processing information like:
  • Spend category worktag.
  • Default fulfillment source.
  • Accounting treatment.
  • Unit of measures and their usage.
  • Lot and serial control.
  • Substitute items.

Objectives

By the end of this chapter, you will be able to:
  • Describe the purpose of the purchase and supplier item.
  • Create and maintain purchase and supplier items.
  • Create item tags and identifier types.

Item Approach for Workday Procure to Pay

In Workday, an item master is a record for purchases from a supplier and items in inventory. It is typically a combination of a purchase and supplier item, or a purchase and catalog item.
The image below illustrates the concept of a unified procurement item by adding the ability to link catalog items and web and punchout items to internal purchase items. All items tie to the purchase item individually. The unified procurement item provides you with improved visibility into goods purchased for internal use.
A diagram of a unified procurement item as described in the preceding text.
Tip
: Workday recommends setting up the purchase item as a manufacturer item and setting catalog or supplier items as supplier-specific items.
Purchase items are goods and services not necessarily associated with any supplier or supplier contract. You can link a purchase item to multiple supplier or catalog items.
Purchase item prices represent standard or common pricing of an item. If the item represents a manufacturer item, the purchase item price represents the manufacturer list price. Purchase item prices are for budgeting and approval purposes and do not represent a contractual agreement with a supplier.
Catalog items are associated with a supplier contract. You can search the catalog for them from your cart. When you select these items in a requisition, Workday automatically issues the PO to the supplier and bypasses the buyer requisition review. You can set up the supplier minimum order quantity for catalog and supplier items. This prevents supplier penalization for not meeting minimum order amounts or quantities on purchase orders. You can link a catalog item to a purchase item.
You can use the catalog item to support your more complex requirements that the supplier item cannot handle.
Example
: There is a requirement to store multiple catalog items (each representing a different unit of measure) for the same manufacturer item.
The supplier item contains attributes specific to the supplier from which you have a contract to purchase items. This includes a supplier item identifier, price, ordering units of measure, manufacturer, and other supplier-specific details about the item. You can set up advance pricing rules for discounts and specials. On the supplier item, you can set up sourcing priorities among multiple suppliers for one purchase item.
Web items are supplier items for goods that you purchase using punchout to a supplier website or supplier network (marketplace) hosted outside of Workday. You can associate web items to purchase items. Workday automatically maps web items to purchase items in requisitions from a punchout supplier when these attributes match:
  • UNSPSC (within the range specified for the spend category of the matching purchase item)
  • Manufacturer Name
  • Manufacturer Part ID
If you enable the spend category for stocking, you can specify the conversion factor between the ordering unit of measure (UOM) for the web item, as well as the base UOM.
The best practice for all items, whether stocked or not, is to define the fulfillment source of the purchase order. The inventory site sourcing rules combined with the item inventory site options should indicate to the system if an item is coming from stock or not. If no inventory sourcing rules exist, use of the fulfillment source on the item occurs. If there is no sourcing rule, it will default to a purchase order.
Set up all inventory items as purchase items. You can have a catalog item or web item that is not associated with a purchase item, but you can only source that item directly from a supplier.
Specify preferred purchase items to highlight in your catalog search during requisitions. This helps guide requesters to order your preferred items, helping you save on costs and helping requesters find the items that they need quickly.
Resource
: If inventory is in scope, you should enroll in the Inventory Management course.
Determination for item pricing should go in the following order:
  1. Supplier Contract line
  2. Advance Pricing
  3. Supplier Information
  4. Purchase Item
Group purchase items to facilitate searching, item selection, and reporting. Items can belong to more than one purchase item group. For example, a laptop could belong to both the Office Supplies and Laptops and Desktops purchase item groups.
When creating an item assignment, you can assign it to item groups or a group it to an item.

Alternate Item Identifiers

Alternate item identifiers are a standard set of codes or values that trading partners (e.g., suppliers, buyers, or customers) use to identify trade items. Examples include:
  • Manufacturer part number
  • Global Trade Item Number (GTIN)
  • Universal Product Code (UPC)
Item identifier types enable you to use standard industry nomenclature and part numbers on a purchase item. You can then enter the detail value associated with the item identifier type on the purchase item. This enables you to only configure alternate or universal item identifier types and values that are relevant to your business.
The alternate item identifiers functionality:
  • Provides a flexible framework to define and capture alternate and universal item identifies, such as;
    • Manufacturer or manufacturer part number
    • On a purchase item
    • Catalog item
    • Web item
  • Provides the ability to search for items using any configured alternate item identifier value from the search catalog UI when creating a requisition.
  • Enables supplier catalog and web items to be automatically linked to purchase items during catalog loads and web item punchouts.
  • Enhances procurement reporting by linking catalog and web items to a purchase item.
  • Provides predefined universal item identifier values for the most commonly used item identifier types (not values).
You enable this functionality by creating item identifier types. When defining alternate item identifier types, keep in mind:
  • They can be specific (SKU) or general (UNSPSC).
  • More detailed item identifier types require more purchase items to track web and catalog item transactions.
  • A purchase item used for inventory will normally be at a SKU or UPC level. This determines the alternate item identifier types for a spend category definition and, ultimately, is used on a purchase item.
  • The alternate item identifier type gets assigned to a spend category.
  • The alternate item identifier type and a value assign to the purchase item.
Once your analysis is complete, use the
Maintain Item Identifier Types
task to create the required values for spend categories and purchase items. Listed below are the fields used for configuration and their related descriptions.
Note
: To use an alternate item identifier on a purchase item, add it to the spend category.
Item Identifier Types
Description
Name
Short name for the item identifier type.
Description
Long name for the item identifier type.
Universal Item Identifier
Select from the Workday-delivered list of item identifiers to enable linking of web items to purchase items during the punchout.
For Item UOM
Define item identifiers that are unit of measure-specific identifiers, such as GTIN and UPN.
Length
Set the maximum length of the item identifier value. Enter 0 to skip the validation when you enter item identifier values in the
Create or Edit Purchase Item
task.
Allow Multiples
This option allows for multiple values for this type that you can add to an individual purchase item.
Allow Multiples per UOM/Manufacturer
This option allows for multiple GTINs for the UOM and manufacturer combination that you specify on a single purchase item.
Item Identifier Type Is Unique
Select to enforce the creation of unique item identifier values for the item identifier type in the
Create Purchase Item
task. You cannot duplicate values across purchase items using this type if selected.
Use In Supplier Catalog Item Mapping
Select to automatically link catalog items to purchase items during catalog loads.
This option is helpful to catalog administrators to quickly identify purchase items for supplier items during catalog loads.
External
Select so that the identifier type is available to view on PDF versions of purchase orders, RFQs, and supplier contracts.
In Use
Usage of the item identifier type on a spend category and, potentially, a purchase item.
Inactive
Select to inactivate the identifier type. You cannot select it for use on a spend category or purchase item.
Item tags are more item identifiers that you can define and use on a purchase item, catalog item, or web item. Unlike item identifier types, these customer-defined item attributes are based on their needs and are then attached to an item.
Example
: Item tags could have values such as or similar to Radioactive, Refrigerated, or Latex-Free.
Item Tags
Description
Name
Short name for the item tag.
Description
Long name for the item tag.
Universal Item Identifier
Associate item tags with Workday-delivered list of item identifiers. Enables the linking of web items to purchase items during punchout.
Inactive
Select to inactivate the identifier type so it can no longer be selected for use on a spend category or purchase item.

Commodity Codes

You can create commodity codes that group similar types of goods and services. Define your own structure or use an industry-based standard taxonomy such as the National Institute of Governmental Purchasing Commodity Services Code (NIGP) or the United Nations Standard Products and Services Code (UNSPSC).
Access the
Maintain Commodity Code Types
task to create and edit commodity codes. Workday recommends that you use standard commodity code structures for data integrity and integration with third-party systems. For example, UNSPSC codes are eight-digit values (with an optional two more digits) of a four-level hierarchy (with an optional fifth level). Segment, Family, Class, and Commodity are the four-primary levels with two 00 decimal digits to enable eight-digit codes for each level. To create a UNSPSC-type code, you must create four levels with a level length of two. Then, Workday automatically associates the code to the parent code and creates the parent code if it does not already exist.
You can directly associate commodity codes to procurement items on these tasks:
  • Create Purchase Item
  • Edit Purchase Item
  • Catalog Load Request
  • Maintain External (Extrinsic) Cart Details

Multiple Ordering Units of Measure

You can maintain multiple ordering UOMs on catalog items and purchase items. You can also enable catalog item maintenance on your purchase item tasks to unify item maintenance work on the
Edit Tenant Setup - Financials
task.
When you select an item on a procurement transaction, Workday populates UOMs associated with the item on UOM prompts. Workday also populates pricing information based on the UOM you select.
For purchase items, you can associate ordering UOMs with the purchase item or supplier information for the purchase item.
When you select purchase items with supplier information on a procurement transaction, Workday populates UOMs from these tabs on purchase item tasks:
  • Supplier Information
    : When the document has matching supplier information.
  • Item Overview
    : When the document does not have matching supplier information or when you create a consignment document type.
You can manage ordering UOMs by:
  • Associating them to a price, conversion factor, usage, and lead time.
  • Configuring default ordering UOMs.
  • Configuring default issuing UOMs.
  • Configuring default stocking UOMs.
  • Configuring the default unit of use for UOMs.
Transaction
Description
Example
Requisitions
Configure your company procurement options to allow workers to select a different UOM on a requisition.
Test tubes are available in cases and boxes with different prices. You can request test tubes in a case or a box, or any of the enabled units of measure:
  • The unit price of a box of test tubes is $25.
  • The unit price of a case of test tubes is $100.
Sourcing
You can source an item in an alternate UOM based on your purchasing needs. Workday adjusts the unit price based on the UOM selected.
A requester can request for 5 boxes (5 boxes = 1 case).
Source one case instead of five boxes as a cheaper option.
Receiving
You can receive a catalog item against a purchase order line in a different UOM than the ordering UOM.
You can also receive a different UOM than the ordering UOM when you have a purchase item with supplier information.
You create a requisition for four cases of jumbo test tubes, then you autosource the requisition to a purchase order with Supplier ABC. You then receive a partial shipment of 200 sets.
Invoicing
The UOM on supplier invoice lines enables you to reconcile invoices with the quantities of items you actually ordered and received.
When you create an invoice line, you can verify that the UOM matches the UOM specified in the purchase order or receipt.
For catalog items and purchase items with supplier information, you can select a different UOM from the UOM on the purchase order or receipt.
Workday displays an invoice price variance on your accounting entry for inventory items when you meet these criteria:
  • A received UOM differs from an ordering UOM.
  • An invoice price differs from a receipt price.
You order two cases (each case contains five boxes) of a supplier item. The supplier can partially fulfill the order and ship five boxes.
You can invoice the UOM as a case or box (or any valid alternate ordering units of measure), ensuring that the matching rules still apply. Workday updates the unit cost to reflect the invoiced UOM.

Just in Time (JIT) Units of Measure

You can configure just-in-time UOMs to enable items for just-in-time replenishment. When you create a just-in-time requisition and select an item, Workday populates just-in-time UOMs on UOM prompts.
If you change a UOM, Workday populates the correct price.
When you select purchase items with supplier information, just-in-time UOMs only populate from the purchase item when the document has matching supplier information.

Packaging String

Packaging strings provide visibility into the different UOMs and their conversion factors. Workday automates packaging string data when you enter a packaging string in the supported format. You can display packaging strings on these transactions:
  • Inventory
  • Procurement
  • Supplier accounts
Example
: Case/10 Box/200 Each means one case contains 10 boxes, and one box contains 200 items.

Configuring a Purchase Item

This table represents some of the key fields on a purchase item.
Option
Description
Spend Category

You can use service items for both goods and service lines in procurement documents.
Default Tax Applicability from Spend Category
Displays when you define spend categories with a default tax applicability.
Default Tax Applicability
Select the tax applicability code to associate with this item on procurement lines.
The Default Tax Applicability overrides the Default Tax Applicability from Spend Category value on procurement lines.
Define tax applicability codes using the
Maintain Tax Applicability
task.
Worktags
Set up related worktags for this object using the related worktag types that you configure on the
Maintain Related Worktag Usage
task. Workday automatically populates transactions with the values in the Default Worktag column when you select the object on the transaction.
Workday also populates the worktags of the transaction with the related spend category and its worktags. When a related worktag from the purchase item and spend category are the same type, the value from the purchase item takes precedence because it is more specific.
Comments
You can use this field to add and update comments about item changes as different workers interact with it.
You can also view comments made on purchase items in the following areas:
  • Item preview in the Related Actions menu
  • View Purchase Item
    report

You can select a default unit of UOM use on the Inventory Site Options tab.
Allow Decimal Stocking Quantities
Select to allow decimal stocking quantities for the base UOM. This enables more precision in the UOM for the item.
Accepting decimal quantities in UOMs determines the reserve quantity in base UOM during the reservation process. The reserve quantity is a whole number if the corresponding stocking UOM on the stock request is a whole number.
Workday automatically converts existing stocking UOMs to accept decimal stocking quantities.
On the Alternate Item Identifiers tab, configure values for alternate item identifier types which:
  • Establish a link between your internal purchase items and manufacturer information.
  • Enable you to search for the purchase item in Item prompts using the alternate item identifier.
Example: Item Identifier Type = Manufacturer Part Number; Value = 9302-37WD.

Workday delivers the following tasks to propose a change of spend category and commodity codes for your purchase items:
  • Cancel Purchase Item Spend Category Request
  • Edit Change Purchase Item Spend Category Request
  • Mass Maintain Purchase Item Spend Category
The task security ties to the
Change Purchase Item Spend Category Request
business process. You cannot change an inventory spend category to a procurement category. Workday does not perform any accounting during the spend category change. It only captures the financial details of the items on the change request at the time of approval.
Use the
Create Purchase Item Request Template
task to create templates for users to complete when mass maintaining or requesting new purchase items.

Item Maintenance and Workflows Using Worksheets

Worksheets are a cloud-based spreadsheet technology built within Workday that you can use to analyze live data in a familiar but secure environment. By enabling Worksheets for purchase items, you can define workflows for requesting, creating, and mass updating purchase items that align with company organizational policies.
When you plan to maintain purchase item information with Worksheets, use this table to understand Workday Worksheets, Purchase Item Request Templates and Types, and how they fit together.
