WfMC Sample Workflow
Use Case
The WfMC sample workflow is a sales order processing scenario.
The XYZE Products Company receives orders from cash and credit
accounts: cash accounts pay by credit card and credit accounts are
invoiced. A suite of three co-operating workflows manages the process
of
receiving orders, arranging payment by credit card or invoice, and
order fulfillment. The business rules and process flows are as follows:
- Received orders are transformed then validated.
- Order amounts from credit account customers must not cause the balance
to exceed the credit limit.
- Order amounts from cash customers must be pre-approved by the credit
card company.
-
If either credit check fails:
- The order is cancelled and a cancellation notification is emailed to the
customer.
- If the credit check is successful:
- The order fulfillment process is started.
- An acceptance letter is composed.
- A order confirmation messages is emailed to the customer.
- The order is passed for fulfillment.
- If the order has not been fulfilled within three days:
- If the order has not been fulfilled within five days:
- The process cancels the order and terminates.
- If the order is from a credit account customer:
- An invoice is created.
- The invoice is emailed to the customer.
- If the order is from a cash customer:
- Their credit card is billed.
- A receipt is created.
- The receipt is emailed to the customer.
N.B. The OBE version of this workflow process differs slightly from
the original WfMC version, which contains several errors, omissions and
inconsistencies. The OBE version is fully functional and is also
event-triggerable.

Applications
Note: In the OBE version all server-side automated processing is
implemented by PROCEDURES. This is because the XPDL specification is
unclear about the semantic distinction between a tool which is invoked
as PROCEDURE versus one which is invoked as an APPLICATION. OBE
semantics assume that, being typically non-interactive, procedures are
invoked server-side whereas applications, being typically
interactive, are invoked client-side (and therefore require non-SYSTEM
activity performers and thus have associated work items).

Solution
Process
Model Description
EOrder Workflow - wfmc-wf-1
- The workflow can either be started manually or triggered by the '
WfMCSalesOrderReceived' application event. (N.B. Event
triggering is an OBE extension - standard XPDL has no
semantic equivalent.)
- The 'Transform Data' activity invokes the '
transformData'
tool, passing the orderString as an IN parameter and
storing the result in the OUT parameter 'orderInfo'.
- If an exception occurs, the 'Raise Alarm' activity starts,
auto-completes, then activates the 'Compose Rejection' activity.
- The 'Check Data' activity checks
orderInfo to verify
it, setting the 'status' OUT parameter.
- If
orderInfo is valid, the 'Check Order'
activity branches the flow according to whether the order is against a
credit account or a credit card.
- If a credit account, the 'Check Vendor' activity invokes the
checkVendor()
procedure which checks whether the account balance would would
remain
within the preset credit limit for that customer. If it does not,
transition 30 activates the 'Compose Rejection' activity. If it
does, the flow proceeds to the 'Enter Order' activity.
- If a credit card sale, the 'Check Credit' activity invokes the
'CreditCheck' subflow. If the credit card authorization request is
declined, transition activates the 'Compose Rejection'
activity.
If successful, the flowproceeds to the 'Enter Order' activity.
- The 'Enter Order' activity passes
orderInfo to the '
enterOrder' tool, storing the result into the '
orderNumber' OUT parameter.
- Once the order has been entered the following three activities
proceed in parallel. When they are all complete, the workflow process
is marked complete.
- The 'Fill Order Subprocess' activity asynchronously invokes the
'FillOrder' subflow.
- The 'Compose Acceptance' activity composes a document of
acceptance (presumably storing it somewhere so that it will be
accessible to the customer via a URL).
- The 'EMail Confirmation' activity composes an email and sends
it to the customer's email address. The EMail message content
contains
a reference to the customer's order number.
FillOrder Workflow - wfmc-wf-2
- The 'FillOrder' workflow is invoked as a subprocess from EOrder, with
orderNumber, orderType and
emailAddress being passed as parameters to the subflow.
- The 'Ship Order' activity invokes the '
shipOrder' tool,
passing orderNumber and storing the result in the '
status' OUT parameter.
- If the 'Ship Order' activity has not completed within three days, this
activates the 'Raise Alarm' activity.
- If the 'Ship Order' activity has not completed within five days the
'Cancel Order' activity is activated, which invokes the '
cancelOrder' tool.
- Otherwise, if this is a credit account order:
- The 'Billing' activity invokes the '
billAccount' tool,
passing orderNumber as a parameter.
- The 'Create Invoice' activity invokes the '
createInvoice' tool, passing orderNumber and
storing the resulting docUri.
- If this is a credit card order:
- The 'Get Credit Info' activity invokes the '
getCreditInfo' tool to retrieve the creditInfo
object for this orderNumber.
- The 'Charge Credit' activity invokes the '
chargeCreditAccount
' tool (implemented as a call to a Web Service) to raise
the charge to the credit card.
- The 'Create Receipt' activity invokes the '
createReceipt
' tool, passing orderNumber and storing the
resulting docUri.
- The 'EMail Receipt or Invoice' activity generates and sends an
email message which contains a link to the receipt or invoice.
CreditCheck Workflow - wfmc-wf-3
- The 'CheckCredit' workflow is invoked as a subprocess from EOrder, with
accountNumber, amount and
cardType being passed as parameters to the subflow.
- The 'Set Credit Info' activity invokes the '
setCreditInfo'
tool, passing accountNumber, amount and
cardType as IN parameters and storing the returned XML
document in the creditInfo OUT parameter.
- The 'Get Credit Authorization' passes the
creditInfo
document to the 'getCreditAuthorization' tool (a Web
Service) and stores the returned result in the
creditStatus OUT parameter.
- The 'Set Order Status' activity invokes the '
setOrderStatus
' tool to convert the creditStatus authorization code into
the status value returned by the subflow as an OUT
parameter.

Deployment and Execution
The EOrder workflow supports both manual and triggered start.
- Deploy the
wfmc-sample.xpdl package.
- Start a workflow instance by either:
- Instantiating an instance of the
EOrder workflow
from the Worklist client.
- When prompted, pasting the contents of an XML order which conforms
to the
$OBE_HOME/examples/config/resources/orderschema.xsd schema,
such as order-1.xml or order-2.xml in
$OBE_HOME/examples/etc/WfMCSample.
- or
- Open a console window and navigate to the
$OBE_HOME/examples/etc/
WfMCSample directory.
- Execute either or both of the commands:
send order-1.xmlsend order-2.xml
- In either case, enable
logging to observe in-flight process activity, or use a worklist
client or the
cladmin tool to probe process instances.
- For each process instance created above, use the worklist client
to locate, execute and where necessary mark work items complete.
Certain work items will present supplementary windows, dialogs or
prompts as they invoke the tools associated with their defining
activities.
