just an FYI - I finally got around to updating the the simple how to guide on the OData Channel API for SP3+...it used to be based on the old SP2 stuff, the following is a list of new features covered in the update H2G:
- shows how to add and activite the service on the Gateway using transaction /IWFND/MAINT_SERVICE.
- shows how to test the service using the FireFox RESTClient plugin - shows how to obtain and use the CSRF token which is required for executing the create and update services
- shows how to use the sap-ds-debug=true query string parameter...this is a very helpful feature when it comes to testing!
Anyway, you can find the updated How To Guide here: http://scn.sap.com/docs/DOC-10466
Hope you enjoy it!
