Other team changed the SOAP web service method and changed the object name.

Use the approach I describe here: forum.appian.com/.../e-107197 to update the node

1. Delete the CDTs related to the Web Service. Make sure you delete all of them, sort by namespace to be completely sure you are deleting all of them

*** IMPORTANT: Missing at least one CDT will prevent the solution from working, please triple check you delete all related CDTs.

2. Open up the process model, right click on the Call Web Service Smart Service - Properties - Setup
3. Temporarily check Authentication Required and typed something in username and password and click Refresh
4. Uncheck the authentication required option.
5. Finish configuring the smart service.
6. Save and publish the model
7. Try again.

thanks it worked

Hi.
I am facing same issue again. After deleting the CDT and refreshing the service it shows array as
Service Input(UpdateDetails)
userName
Password
UpdateDetails(UpdateDetails^1)
Var1
Var2

Do I have to restart the server? Everytime I have to restart the server?

The behavior you are seeing indicates you missed one of the CDTs that are in use by this web service. Make sure you delete all of the related ones.

I cannot see the UpdateDetails CDT in system under data... and no other process model we have used this particular web service function call. I have deleted all the CDT related to that web services for all functions.

The UpdateDetails is gone that's fine but it seems there's a top level CDT that hasn't been deleted yet. Whenever you refresh the services in the node you should get a warning click on it to see what CDT needs to be deleted.

I have deleted all the CDT.

just FYI.. We resolved it creating new process model in another environment, after that exported the CDT and imported those into our environment which had problem.
