How to add an Activity in a Sales Quote through a Web service.

Hi Experts,

I need to update a Sales quote from a Web Service to add an Activity. I Tried with a Web Service for the Sales Quote but i don´t recognize the node to fill the Activities.

In the UI Designer shows that Table like an association called [AppointmentReference] but i don´t cannot to identified in the WS.

Maybe i need to execute another WS?

I am using a WS created in the PDI for the CustomerQuotes.

Another problem i have, I don´t know the typeCodes for the Activity.

thx!!
