Exposing an operation in a service provider model and using it in a service consumer model

This topic describes how to exposing an operation in a Service Provider model and use it in a Service Consumer model.

  1. Create a model that provides functionality that you want to expose as a service. An example might be a method that returns a list of records from a back end database, such as SAP or PeopleSoft. The model should provide a method (that may or may not take arguments) that returns the desired data. The returned data can be directly returned from the method, or placed in a known schema-typed variable.

    1. Add a Service Definition builder to your model and a Service Operation builder for each method you wish to expose.

    2. Save and close the Service Provider model.

  2. Create or open an existing model that you want to have consume the service.

    1. In this Service Consumer model add a Service Consumer builder and select the provider model and, optionally, the operation.

    The Service Consumer builder will add a Data Service and local methods to your model that can be used to invoke the service. The service inputs and outputs will be exposed as Variables.

  3. Add builders to your model to invoke the service operation and process the output.

    1. Use a high-level builder, such as the View & Form builder, to invoke a service operation, and display its data.

  4. In the View & Form builder, use the View Method input to select the Data Service operation DataService/consumer builder name/operation name (for example, DataServices/orders/getOrders).
