I woud like to change this extension field in third party system outside C4C, using web service or OData service.
I have created a new action in BO CustomerQuote:
And implement this custom action, simply setting extension field to a constant value ( for example 4 represents “Production in process” ).As the last step, import the WSDL file in SoapUI application and fire the web service. In the screenshot below, my aim is to execute the custom action on Sales Order 9000000318 via web service execution.
