Creating a Test Case with a Series of Operations from Different SoapUI Projects

Hi All

I have several soapi ui projects (i.e. several web services) each have one or more operations. One soapui
project (i.e. one web service) is the calling process for other soapui projects (i.e. other webservices) as
partners. I have created mock services for all the partners in different soapui projects.

I want to create a test case in the soapui project for the main calling process which can call the operations of other soapui projects(i.e. other web services) in a sequential manner.

I am trying to emulate the whole process.

Thanks in advance.

Cheers
Jamith
