Hi Steve,
Thanks for the information.  Our issue is that one forms instance is started by Workflow and then routed to an internal user.  Another form is started by a member of the public.  We need to update a value on the first form with a value collected on the second form.  Since we haven't been able to capture the FormsBPInstance ID from the first form using the Retrieve Forms Process Variables in the step after the Invoke Business Process task, we can't create a workflow to update the necessary value.

Hi Jen

The way I have approached this in the past, is in the Initial Form Process, is to have a timer event that will run a workflow to check the Repository for the Public Form Submission and then grab the data from there to update the Form in process. When you save the Public Form, you can either save the data required to a Metadata field or to save the InstanceID into a MD Field which you can use as a variable to query the form data from the DB

An example of a Process may look like this to trigger the workflow

I have a variable call DocFOUND in my Form that gets updated with either YES or NO, which is used in the condition after the workflow. If yes, it updates the form, If no it stops and does nothing. The Timer does not Interrupt the process, it is set to repeat, which is why if NO do nothing and the workflow will trigger again on the next cycle. When it is found I kill the task with a Signal Event and then raise the Task again but this time it has the new task populated from the workflow

To Get to the Retrive Field Value I had to use the Token Dialog as it doesn't show up in the Activity Dropdown natively.

Also, note that the Form Data is only as available as long as you Forms data retention policies.

I didn't show the rest of the workflow beyond this, I figure you know where I was going

Hope this helps
