Understanding the Shift from FAS to Workday

Workday's Foundation Data Model (FDM) represents a significant shift from the legacy Financial Accounting System (FAS) and its chart of accounts structure. In Workday, worktags have replaced the traditional use of account codes and organization codes, offering more flexibility, transparency, and consistency in how financial data is classified and reported.

To help users understand this transition, we’ve created a comparison of key differences between the FAS chart of accounts and Workday worktags, including terminology changes, structural updates, and examples of how transactions are coded.

This resource is especially helpful for users familiar with the legacy system who are adjusting to the new FDM structure in Workday.

Legacy FAS Budget to Workday Worktag Mapping

As part of the University of Washington’s transition from the legacy Financial Accounting System (FAS) to Workday Finance, each legacy FAS budget number was mapped to a corresponding set of Workday worktags.

These mappings were created for conversion purposes only and reflect the system configuration as of June 30, 2023, the go-live date for Workday Finance. Since go-live, some worktag assignments have been updated to better reflect current operational and reporting needs. Users should not rely on this mapping for ongoing transactional guidance without validating current Worktag structures.
