Foundation Data Model (FDM)
Reference Guide
Jump to:
Overview
This reference guide explains the core of Workday Finance – the Foundation Data Model, or FDM. The FDM is WashU’s chart of accounts, essentially the accounting structure for a business or organization. It drives how expenditures, income, assets and liabilities are classified.
This framework supports all financial, management, and operational reporting across the university. The structure is composed of data elements called “worktags” and allows for multiple worktags on each transaction for greater reporting capabilities. The FDM makes it easier and faster to understand WashU’s financial health from the university-level to the school- or unit-level.
Changes and Additions to Ledger Accounts, Revenue Categories & Spend Categories
The Foundation Data Model (FDM) Viewer security group can now access RPT6961 – WU – New or Edited Ledger Accounts, Spend Categories, and Revenue Categories to review additions and changes made on Ledgers Accounts, Spend Categories and Revenue Categories over a specified date range.
Requesting New or a Change on Ledger Accounts, Revenue Categories & Spend Categories
- Financial users will identify the need for new or a change to: Ledger Account, Revenue Category or Spend Category
- Complete all fields on the proper request form:
Ledger Account Request Form
Revenue and Spend Category Request Form
- Create a ServiceNow ticket using a Get Help request and indicate the following for each field:
I need support with: Finance
Specify the support area: Workday Finance
Select the category you need support with: Workday Core Finance
Subcategory: Foundation Data Model (FDM)
Brief description: Provide brief description of request
Additional Details: Provide additional details
Add Attachment: add Ledger Account Request Form or Revenue and Spend Category Request Form as an attachment
Select: Submit
After submitting the ServiceNow ticket, the Workday Support Team (WST) will review the request. The response timeframe will range from 2 to 7 days. WST Reviewers may request additional time, as needed. If a requested item is considered urgent, the requestor should indicate this in the ServiceNow Ticket. If the request is approved, the requestor will be notified of next steps, if any are required.
Data Elements: Ledger Accounts & Worktags
The key elements that make up the FDM structure are Ledger Accounts and Worktags.
Ledger Accounts
- Ledger: The record for all accounting entries, where all journals post.
- Ledger Account: The sub-classification of a debit or credit for reporting purposes. It is required on all transactions and drives financial reporting, including external reporting and compliance requirements. Examples of Ledger Accounts are categories of revenue, (such as tuition) and expenses, (such as lab supplies).
- Ledger Account Type: Classifies the Ledger Account and the natural balance of the account (debit/credit balance).
- Ledger Account Summary: Hierarchy structure that contains Ledger Accounts and is used for financial statement reporting.
Ledgers in Workday
Commitment
- Pre-Encumbrance

- Purchase Orders, Salaries for filled HR positions
Actuals
- Actuals

- Invoices, Payroll Actuals, Fringe, Revenue
Ledger Account Structure

Ledger Account Numbering
The Ledger Accounts in Workday are numbered to follow these ledger series, which is relatively consistent in the accounting world. If you are not familiar with these categories, this grid is a great reference tool to have handy when searching for the correct ledger account to select on an Accounting Journal (manual journal) entry.

Ledger Account Hierarchy Example

Worktags
Worktags: The data elements, or key words, attached to all financial transactions. They clarify the business purposes of financial transactions and establish common relationships between them through classification. They can drill down to more detail or roll up for financial reporting purposes. Several Worktags are required on all transactions.
- Worktags come in three types: Driver, Related, and Optional.
- When a Driver Worktag is entered, the Default Related Worktags are auto-populated, depending on the chosen Driver. In addition, the Driver controls the approval process.
- Allowed Related Worktags are other available values that can be used in place of the Default Related Worktags that were populated.
- Optional Worktags serve to further classify a transaction for more detailed management reporting.
- Some additional Optional Worktags will default on transactions, depending on the chosen Driver.
- If a required worktag is not entered, Workday will display an error message.
| Worktag | Driver vs. Related vs. Optional |
|---|---|
| Cost Center | Driver or Related on Gift, Grant, Project and Non-Carryforward |
| Gift | Driver |
| Grant | Driver |
| Project | Driver |
| Non-Carryforward | Driver |
| Company | Related, Manually Selected on transactions |
| Program | Related, Required worktag |
| Business Unit | Related, Required worktag |
| Fund | Related, Required worktag |
| Function | Related, Required worktag |
| Region | Related |
| Assignee | Related |
| Debt Vehicle | Optional, Specific Use |
| Designated Reserves | Optional, Specific Use |
| Academic Period | Optional, Specific Use |
| Expense Treatment for Award Processing | Optional, Specific Use |
| Appropriations | Optional, Specific Use |
| Faculty Financial Reporting (FFR) | Related or Optional, Specific Use |
Ledger Accounts
The train illustration emphasizes how the driver worktag “drives” the defaulting and usage of the related worktags.
Driver Worktags: Every transaction must have a driver worktag. These worktags are chosen by the person entering the transaction.
Related / Allowed Worktags (Required) : Cost Center, Business Unit, Program, Function, and Fund are required on transactions. These required related worktags will automatically populate based on the value of the driver worktag selected. However, these default worktags can be overridden if needed.
Additional Allowed Worktags (Optional) : The light blue represents optional worktags that are “allowed” to be used to provide more granular reporting capability
Required Revenue and Spend Category Worktags: When an entry is recorded to a revenue or expense ledger account, a revenue or spend category is a required worktag. These worktags are used to granularly report on income statement transactions for management reporting
Not shown here, Company is a required worktag, however it does not default based on driver. For most entries, Company will be CP00001: Washington University in St. Louis

Required Worktags
All of the following worktags are required on every transaction:
| Worktag | Definition | Examples |
|---|---|---|
| Cost Center | Lowest level of a fiscal responsibility and management within company Level at which budgets are created and maintained Typically has people assigned (Default Cost Center) Will have Related worktags (Allowed and Default) Only one company for each Cost Center | Hierarchy: CH00225 Ophthalmology Research – Cost Center: CC0000746 Ophthalmology Research Clinical Trials Hierarchy: CH00264 Social Work – Cost Center: CC00001622 Brown School - Faculty Hierarchy: CH00371 Chancellor – Cost Center: CC0000446 Chancellor Emeritus |
| Company | Different legal entities are arranged in a hierarchy to support security, business processes and tasks that are separate for audit and external reporting purposes Can invoice other companies Can payroll cost allocate across companies Company has hierarchies | CP00001 Washington University CP00002 Washington University Physicians in Illinois (WUPI) CP00007 Washington University Regional Physicians (WURP) CP00009 Quadrangle Housing Company |
| Program | Identifies additional level of detail, allowing for grouping and reporting of various business activities that span across multiple cost centers, spend categories and revenue categories, etc. No budget check by program At times, certain program worktags may be directed to be used consistently across the university. Example: COVID Since this is required, if not applicable, the default should be set to PG00002 Non-program Activity Includes payor information from EPIC Includes worktags for types of cost sharing and salary over the cap | Hierarchy: PH00003 Recruitment – Program: PG00098 Recruitment (Fellow) – Program: PG00103 Recruitment (Student) Hierarchy: PH00012 Diversity & Inclusion – Program: PG00003 Diversity Admissions Hierarchy: PH00021 EPIC – Program: PG00019 Blue Shield – Program: PG00027 Managed Medicaid Hierarchy: PH00002 University Programs – Program: PG00046 Fundraising Activities – Program: PG00407 COVID Expenses – Program: PG00408 IT Related Expenses |
| Business Unit | Specifies the ownership of reserves and serves as a basis for balance sheet reporting by school Value is always derived by the cost center and cannot be overridden by the user Each cost center can only have one business unit | Hierarchy: BX00002 Danforth Schools – Business Unit: BU00016 A&S Reserve Hierarchy: BX00013 Med School – Business Unit: BU00296 Siteman Cancer Center Tissue Procurement Core Recharge Center |
| Fund | A method of accounting based on the University’s designation of funding categories, driven by level of restriction Alternate Hierarchies for Management Report vs External Reporting needs Default fund is set on each driver worktag | Hierarchy: FH004 General Operating – Fund: FD001 General Operating Fund Hierarchy: FH007 Other Funds – Fund: FD007 Plant Fund Hierarchy: FH001 Organized Research Funds – Fund: FD004 Grants & Contracts – Federal |
| Function | Used for mission based reporting and NACUBO functional classification; 2 alternate hierarchies Required on all Revenue and Expense transactions End user will need to pay special attention to this worktag and review default on each transaction | Hierarchy Function: FX10002 Research Hierarchy Mission: FX00002 Restricted Research – Function: FN00002 Organized Research Hierarchy Function: FX10001 Instruction Hierarchy Mission: FX00001 Clinical Practice – Function: FN00012 Clinical Administration |
Cost Centers & Cost Center Hierarchies
Cost Centers and Cost Center Hierarchies show how budgets (revenue and expenses) roll up in the university. Cost Centers must be included in every transaction and are similar to what are called departments, or department and fund combinations. One department or department-fund may be represented by several cost centers. Alternately, multiple departments or department-funds can roll into a single cost center.
Cost Centers are organized into hierarchies that can be used for reporting at various levels, depending on the needs of the unit, division, school, or university. They can drill down to more detail or roll up for financial reporting purposes.
Example: Danforth
Biology and Biomedical Sciences in Arts and Sciences, the Department Level Cost Center Hierarchy is one level above the lowest level (the Cost Center) and five levels below the top level.

Example: Med School
Pediatrics is two levels above the lowest level and three levels below the top level.

Default Cost Center

- A default cost center is assigned to every position in Workday.
- That default cost center is charged for payroll costs if a worker in that position is paid but no Payroll Costing Allocation has been defined.
- WashU Non-Workday applications use the default cost center to determine what positions and people are in the Department.
How Does This Work?
two possibilities for an example position: Assistant professor of psychoceramics
| Default Cost Center | The Result |
|---|---|
| Default Cost Center CC0001234 Psychoceramics Department Chair, Non-Funded Payroll CC0001234 is Assigned School of Psychoceramics Dean’s Office as a Department Level Cost Center Hierarchy | RMS* and other non-Workday Systems will put this Assistant Professor in the CH00012 School of Psychoceramics, Dean’s Office |
| Default Cost Center CC0003456 Psychoceramics Department, Ancient Pottery CC0003456 is Assigned Ancient Pottery, School of Psychoceramics Department Level Cost Center Hierarchy | RMS* and other non-Workday Systems will put this Assistant Professor in the School of CH00023 Ancient Pottery, School of Psychoceramics |
