Dynamic Parallel Processing Question

Fri Feb 21 12:11:57 EST 2014

Thank you Rina and Kjetil for your suggestions.  After thinking about what you said, I came up with this idea that worked pretty easily:

First I defined an Index field of type SWC_INDEX in the local container of the block step.

I modified the binding between the workflow and the block step to pass the PARFOREACH_INDEX to this new INDEX field:

I then modified the binding of the User Decision step within the block to pass the WI_RESULT back to the original Table_of_Approvers.User_decision field indexed by the new INDEX in the block's local container:

This allowed me to capture the user decision back in the original multiline element without having to define a new table or changing the order of the original table:

Thank you again for helping me to "think outside the container"!!

You can change the assignment type from ASSIGN VALUE to APPEND TO TABLE in the binding from the parallell task back to the workflow container, that should do the trick I believe.

I think the easiest solution would be to create another table container element and append to that - depending on how you plan on using this.

In a separate step (after processing of the parallell task was complete you could then replace the contents of the original table with the content of the return values table.
