What items must a report have for you to use it as a data source...

To use a custom report as an integration data source, especially through Report-as-a-Service or an EIB-style extract, the report must be configured so Workday can expose its output in a structured service format. Enabling the report as a Web Service allows the report to be called externally or used by integration tools. The Namespace is required so the XML output has a defined structure and can be referenced properly. XML Aliases for fields, group column headings, and prompts are also required because they control the XML element names used in the integration output. Web service aliases and “linking fields” are not the correct required set. Without these report settings, the integration cannot reliably consume the report as a service-based data source.
