Does anyone have any idea how I could link all related workflow?

I kick off a separate workflow for each line on a customer's PO. I'd like to be able to identify when all workflow for that PO is completed (could have one, could have 99), any ideas?

Could you use one main workflow then have all the others linked back to it using the Related: Request field? A buttons shows up (in the sub-menu area) that shows all requests related to that one. Are you using Event Manager to create the workflows? If so, another idea would be to copy the PO# into the request then search by that field in Synergy.

You could take this one step further by creating a custom ASP Page that would show all of the requests for that particular Purchase Order and their statuses. This would give you a visual display if the workflow is Open, Approved, Rejected, etc. This ASP page could be saved as a Favorite or linked to a Start Page with a Search for a specific Field in a request, Account, Date Range, etc.
