Known gotchas
Workday SOAP responses are large XML documents; always request only the fields you need using Response_Group filters to avoid timeouts on large tenants
Supervisory org hierarchies in Workday may not map cleanly to cost-center or geographic hierarchies; confirm which org type represents the reporting structure before building the sync
Workday Integration System Users require explicit domain security policy grants; missing grants cause silent empty responses rather than permission errors in some API versions
