Inbound webservice implementation

Hi!

I have a task to implement an inbound webservice in Siebel. The webservice itself query data from custom tables and send a decision (string) according to the queried value. As I see it differs from the tutorials in the bookshelf, it uses multiple custom BO, BC, just query data not modify it, that is why I ask here the whole method because I am not sure about the steps I need to do.

I think I need the followings:

- Administrative setting: Set a new inbound webservice on UI at Administration - Webservices / Inbound webservices (which is calls a workflow)
