A service might need to start or interact a business process
definition (BPD) instance to enable a human-centric interaction. For
example, the service might encounter an unexpected business situation
and need human interaction to resolve it. An SCA import can be created
to start or interact with a BPD instance.
Before you begin
For imports that start or interact with
a BPD instance from a Service Component Architecture (SCA) module,
the authenticated user role must have at least deployer and monitor
roles.
Procedure
To create an import to start or interact
with a BPD instance, follow these steps:
- From the Business Integration view,
expand the process application and right-click the BPD you want to
start. The available BPDs are listed under Processes.
Select Create Import. Alternately, on the assembly
editor palette you can expand Outbound Imports,
and then select Business Process Definition,
drag it onto the canvas and select the BPD from the dialog box. You
can also do one of the following procedures:
- If you are working on the assembly diagram, you can drag the
BPD from the Business Integration perspective onto the assembly editor
canvas. It displays the Create Import dialog.
- If you are working in the BEPL editor and want to start a
BPD from BPEL, drag the BPD from the Business Integration perspective
directly into the BPEL editor:
- If the BPD contains a None Start Event and does not contain any
start or intermediate message events:
- If the BPEL process is long running, the SCA import is created
with a request-response interface.
- If the BPEL process is a microflow, the SCA import is created
with a one-way interface.
- If the BPD contains a Start or Intermediate Message Event, or
if there is no None Start Event, a dialog opens that explains that
you must create the SCA Import manually by adding the BPD to the assembly
diagram.
- In the Create Import window, all the exposed
BPD interfaces are listed. Select any combination of one or more interfaces
for the Import.
- The Available request-response interfaces section
lists interfaces that start the BPD instance and receive its outputs
as a response from the BPD instance when it completes.
- The Available one-way interfaces section
lists interfaces that start the BPD instance or interact with an existing
BPD instance. For one-way interfaces, there is no response returned
from the BPD.
- An import is created and added to the assembly editor canvas.
