Each integration requires an integration design and field mapping documentation. The integration team is offering agencies a crosswalk integration option to aid with remediation work of some legacy systems during the implementation timeframe or excessive temporary remediations to bridge gaps between phase 1a and phase 1b functionality. The integration team is providing the crosswalk for legacy AFRS COA to/from Workday FDM. These field mappings will be used by OFM to create updated Data Sharing Agreements (DSA).
