When you create a mapping, you can associate a Workday connection and an operation. Based on the Workday WSDL version and module you specify in the connection, the Secure Agent connects to the corresponding web service in Workday to access, transform, or deliver data. The request and response are SOAP messages. The SOAP request and response messages contain hierarchical data, where the data follows an XML schema. If you want to write data to a relational target, the Secure Agent converts the hierarchical data fetched from Workday to relational data.
