Example of Invoking DTU from a Workflow: Auto Order Web Service

The Auto Order web service exposes Siebel's auto order function as a web service. It takes a quote row ID as the input argument, creates an order based on the quote, and returns a quote integration object. The web service is implemented by a workflow.

To see how the workflow SISOMAutoOrderWebService invokes the DTU

1. In Oracle's Siebel Tools, locate the workflow SISOMAutoOrderWebService.
2. In this workflow, select the step DTU Auto Order, which uses DTU to create a new order from a quote using the "DataTransfer" method.
3. Display input arguments, which have the values shown in the following table:

   Input Argument	Sequence	Type	Value	Property Name
   DataMapObj	1	Literal	QuoteToSalesOrder
   Operation	2	Literal	Insert
   Option	3	Literal	/BatchMode/NewSrcBusObj
   RowID	4	Process Property		Object Id

   Notice that there are some subtle differences from the input arguments of the previous example:

   • Here, RowId is explicitly passed in as an argument, but when you use a signal, the order management infrastructure implicitly passes in a RowId argument.
   • The Option argument contains "NewSrcBusObj". In the previous example, since signals pass the "RowId" argument instead of the buscomp instance into DTU, a new instance of the source buscomp is always created. This workflow specifies its Business Object as Quote. As a result, DTU receives a reference to the quote business component as part of the invocation context. Because you use NewSrcBusObj in this argument, DTU does not work off the instance of the quote buscomp associated with the workflow. Instead it creates a new instance of the quote business object. For information about why NewSrcBusObj is used, see Performance Tuning for DTU.
4. Display the output argument for this step, which has the values shown in the following table:

   Property Name	Sequence	Type	Output Argument
   ActiveOrderId	5	Output Argument	&OrderId

5. The newly created order ID is output through the DTU named parameter &OrderId. The parameter is defined in the data map Header component data map field view, which has the values shown in the following table:

   Order	Source Type	Source	Destination Type	Destination
   52	Parameter	&OrderId	Expression	[Id]
