Employee on boarding Process inn WorkdayThere are various operations which need to be called to complete on-boarding process in the workday.

1. Transfer a hiring data from jobvite to workday2. Hire a employee and enter the data into workday and employee data information need to

send to ERP system.3. Employee person data, contact information and employee profile data need to updated and

same need to transfer to ERP4. Employee benefits need to be updated in Workday and same need to transfer to finance

system. Etc

To accomplish above steps you need to deal with different operations of Staffing, HRM, Talent and Benefit WSDL of Workday.

But as soon as you import more than WSDL of Workday in single project (composite) using webservice adapter, project start giving compilation error due to duplicate namespaces in different WSDL.

Which means, we cannot import more than one WSDL in on composite.

Indeed, Workday Modules and hence WSDL are cross dependent. Which effectively mean is that to accomplish most of the integration business processes you would be touching two or more WSDL of workday. And if you need to create a separate project for each operation and project call other project will make whole integration very complex and almost unmanageable.
