First of all, it is extremely difficult to understand your message. You posted your question in the title and that is hardly difficult to find its meaning in your message. From your question, I'm not sure if you try to create a new approach to call the WSDL file or if you try to benefit of IP approach to gain access to the tables.

Note that within a Web Service, even if you can make it run from the CreateObject() approach, natively in a VFP command approach, it doesn't mean that will work in the WS. The WS is also bound to specific priviledges where some situations like these may require adjustments.
