Workday COA Information and Resources

Workday COA Request Forms

All Workday COA forms are subject to change as we start working in our new system. Please continue to come here to get the most updated forms.

Submit all forms to By submitting requests to COA, you certify that this request meets the COA segment definitions and business use cases detailed above. PLEASE DO NOT SCAN FORMS FOR SUBMISSION. If you scan them, COA cannot add the other information required for processing; you will be asked to resend the original excel files and/or writeable PDF forms.

Each form is set up to handle a single request. If you have a large volume of requests, please DO NOT complete a separate form for each item. Instead, please complete one form’s “General Information” section and include in excel the items in the “Information from Requestor” section. Ex: If you need to make a modification to 10 projects, complete one project modification form with an excel sheet containing the ten rows for the 10 projects requiring modification.

Workday COA Segment Values

We are pleased to share listings of certain COA segments and/or provide you with the links to reports in Workday. Please refer to the Chart of Accounts definitions to get an understanding of how these values should be used. You may be required to log in via CAS in order to view these documents.

Tools - Transition from Oracle PTAEO to Workday COA

The following suite of tools has been made available by the Workday @ Yale Program to help the business community understand the transition from the Oracle PTAEO to the Workday COA. The goal of these tools is twofold:

  1. Provide departments with direct access to Oracle PTAEO to Workday COA mappings
  2. Provide context to the mappings through “converted” financial information – how certain financial transactions and balances will look in the new Workday COA

Departmental business offices and central financial staff will use these tools to help support the continued refinement of COA segment mappings and development of local and university charging instructions. The conversion mappings will continue to be available for refinement over the coming months, until the early spring when the Workday @ Yale program will stabilize and eventually “freeze” during implementation.

What PTAEOs are subject to “conversion” and included in the results of these tools?

The Workday Financials team will be converting four years of historical information into Workday (FY14 – FY17) and two years of budget data (FY16 – FY17). This includes only the net impact of transactions, not the transactions themselves. We are mapping to the Workday Chart of Accounts all of the PTAO combinations required to support this conversion.

New PTAEO combinations are added to the conversion tools weekly as they are used in Oracle financial systems. If you are looking for a PTAEO combination and do not see it in the mapping or conversion tools it means:

  1. That PTAO/PTAEO was never used in Oracle or YBT, or has not been used during the conversion period.
  2. Is new and has not been used yet. When it has been used, it will be brought into the mapping and conversion tools.

Reminders about Conversion Tool Output:

The conversion mappings are designed for historical financial information only and is only a starting point for the segments that you will use starting July 2017. Please check with your business office for final charging instructions on Workday transactions.


PTAEO to Workday COA Mappings

User Guide - Brio

This is a BUG format report dashboard that will provide direct, on-demand access to the PTAEO to WD COA mappings.

This report dashboard does not provide financial transaction or balance data. Certain reports will contain columns formatted for business office staff to use in connection with unit mapping update requests to COA. The COA mappings are updated weekly.

*See reminders above this table*

PTAEO to COA Converter

User Guide – Enter

User Guide – Batch

This is a web-based tool that converts a single PTAEO to the full Workday COA string. It can also be used for batch uploads of PTAEOs. This tool contains segment-only conversions and does not provide financial transaction or balance data.

*See reminders above this table*

BUG307b Sortable Detail Transaction with Workday Chart of Accounts User Guide – 307b A copy of BUG307a is being made available as BUG307b which adds a column for each Workday COA field that corresponds to the Oracle PTAEO for FY14-17 transactions.

YBT “COA Viewer”

User Guide – YBT Viewer Two reports have been developed for current YBT users which show budget or actual data for a given fiscal year grouped by Workday cost center and ledger account only, or by multiple COA segments.
DWH Views for Technical Staff User Guide – AdHoc This document describes tables and fields that are available to technical staff to support system remediation. Ad hoc queries should NOT be used to understand individual segment or PTAEO conversion; for this use the mapping brio report dashboard above.

COA Validation Tool

User Guide- Enter

User Guide - Batch

This is a web-based tool that validates Chart of Account (COA). This tool can be used for validating both a single set of COA charging instructions or a batch of COA charging instructions. In addition to validating each individual COA segment, the validator also looks at the combination of certain COA segments to ensure they are valid. The tool shows a set of pre-determined validation error messages upon validation of segments.

Note: The tool validates INDIVIDUAL SEGMENTS ONLY to indicate if that segment is valid for transactions in Workday. The tool is unable to perform all of the transaction-based validations that exist in Workday. As a result, it is possible that the segments will indicate valid in the tool and could result in an error upon transaction process/import in Workday.

COA Validator and Integration Hub Access Request Form

COA Converter/Confirmation Tool No guide available

This web-based tool allows ISPs and other units to upload a spreadsheet of PTAOs with identifying information, and convert them to WD COA based on the Workday mapping tables. The tool batches uploadsand sends one file to the Lead Administrator that was mapped to the COA on 7/20. The LA can validate the COA.  Contact: Rick Dwyer

COA Confirmation Tool Instructions found inside of tool

This tool is best used on a small number of PTAEOs that have already been converted. It allows units to correspond with Lead Administrators about converted charging instructions. This tool should not be used to confirm large numbers of PTAEOs because it requires business offices to confirm every PTAEO. Contact: Nick Appleby

The Oracle COA to Workday COA conversion data will be made available in the Data Warehouse (DWH). Prior transactions (FY14-FY17) are “tagged” with new Workday COA in the DWH (Consolidated Transaction Table). Prior year procurement source transactions (FY14-FY17) are “tagged” with new Workday COA in the DWH (Expense Reports, Purchase Orders, Invoices). The tools below will look to this segment conversion data and these “tagged” transactions.

A Note about Terminology

Until March 2016, the Workday @ Yale team had used the term Financial Data Model (FDM) to represent the Workday Chart of Accounts, the full Workday data structure and individual segments of the chart of accounts. Please note the following terms below that will be used from April 2016 forward:

Today we call it … Tomorrow we will call it … What is it?

Oracle Chart of Accounts

Chart of Accounts


Workday Chart of Accounts

Chart of Accounts


General term to describe the full set of data points used for standard accounting and financial reporting.

In Workday this includes delivered pieces of the Workday Financial Data Model (FDM) and also some worktags that are configured by Yale.

COA Segments COA Segments

Each individual piece of the chart of accounts - the buckets.

  • Oracle Project, Org, etc.
  • Workday Program, Cost Center, etc.

The list of values for each segment are called the “segment values”.

Charging Instructions


Charging Instructions Accounting string - PTAEO
Expenditure Type Ledger Account COA segment used for general ledger accounting (revenue, expense, assets, liabilities)
