AX2009 workflow element events

Hi All,

In AX2009, I’m having trouble understanding the different workflow events and when they are triggered.

My information source is http://msdn.microsoft.com/en-us/library/cc588240(v=ax.50).aspx

I’m unable to find the answers in the Microsoft documentation, or on the internet.

Unfortunately, no-one in our company has any technical experience with workflow development, so I cannot ask a colleage.

That’s why I’m posting my question here, in the hope that someone can shed some light on this.

I know there are basically 4 WorkflowElement outcome types:







AOT name in case of



AOT name in case of



Outcome Type



Task



Approval



Complete



Complete



Approve



Return



Return



Reject



RequestChange



RequestChange



RequestChange



Deny



Deny



Deny

In the AOT, there are properties on workflow and its elements to enter the EventHandlers.



LEVEL



Object property



Workflow



CanceledEventHandler



CompletedEventHandler



ConfigDataChangeEventHandler



StartedEventHandler



WorkflowElement (Task/Approval)



CanceledEventHandler



StartedEventHandler



WorkflowElementOutcome



EventHandler

In case of the Element Level event handlers, I’m confused.

This is where I think the EventHandlers should be entered:



Event



On WorkflowElement



properties



On WorkflowElementOutcome



properties



WorkflowElementStartedEventHandler



yes







WorkflowElementCanceledEventHandler



yes







WorkflowElementCompletedEventHandler







yes (type=complete)



WorkflowElementReturnedEventHandler







yes (type=return)



WorkflowElemChangeRequestedEventHandler







yes (type=requestchange)



WorkflowElementDeniedEventHandler







yes (type=deny)

What is the difference between a Denied and Canceled?

When you Cancel a workflow, does that first trigger the Deny on the WorflowElementOutcome, and then the Cancel on the WorkflowElement?

Also, the documentation mentions: (note with Element Level Event Handlers)

The Return and ChangeRequested events share the same state in the recommended workflow state model. You can implement these two different events to distinguish between a workflow that is returned and a workflow that only needs a change. However, in both events, the behavior is the same in that a work item is created, and after the work item is complete, the document state is returned to Started.

I’m not sure what they mean here by “document state”. Do they refer to the “Workflow State” mentioned in “Approval State Transitions” (http://msdn.microsoft.com/en-us/library/cc604518(v=ax.50).aspx)?

If so, there’s no state “Started”.

Bjorn.
