Integrating with Navision : Complex data type as response

Hi,

First of all, I am not really familiar with Navision as my company don't really use it. But I am working on a project that needs to integrate with Navision which our client uses. So I'm sorry if I get some of the concepts wrong.

I am calling a web service which i believe is a code unit function from a .net application. Now the web service function returns only string but I am expecting the service response to be an array of objects ( complexType).

My question is, is complex type allowed as a response?
