Dynamic Parallel Processing Question

[Bratzler, Loren]

I have a question about Dynamic Parallel Processing.  I am wondering if it is possible to pass results back to the multi-line element in the main workflow container from the LINE element in the individual parallel tasks?

Here is my test example:

I created a simple test workflow with a Dynamic Parallel Block (this is the only step in the test workflow):

The Parallel Block is designated as ParForEach because I want the approval tasks to go to all approvers at the same time:

The Parallel Processing for the block is based on the multi-line element TABLE_OF_APPROVERS:

The TABLE_OF_APPROVERS element is a structure that has an Agent, an Item Number, and a Result field:

I have set up the binding to pass the indexed multiline element of the workflow container to the LINE element in the step container.  I also set up a return binding to pass the LINE element back to the indexed multiline element.  This was what I was hoping would allow me to update the multiline element in the workflow container but it does not appear to be working:

For the User Decision step within the block, I have defined the Agent to be the Approver from the LINE element:

And in the binding for the User Decision step, I am passing back _WI_RESULT to the User Decision field on the LINE element:

When I test this in SWUS, I define two entries in the TABLE_OF_APPROVERS multiline element:

The workflow runs and correctly creates two approval tasks as expected.  One user Rejects and the other user Approves:

If I look at the containers for the individual Parallel Block steps, I can see that the LINE elements are getting updated with the User Decision:
[cid:image012.png at 01CF2D53.999D6BC0]

[cid:image013.png at 01CF2D53.999D6BC0]

But when I look at the main workflow container, the multiline element did not get updated with the User Decisions:
[cid:image014.png at 01CF2D54.5689D4D0]

So is it possible to do what I am trying to do here?  Can I pass results from the individual parallel steps back to the multiline container element in the main workflow?
