Creating check point to verify data

[Seba]

I have created a workflow that analyzes the pending "PO, Line" that has not been received, and sends email notifications to suppliers inquiring about the status of these materials. This workflow runs twice a week. To avoid sending the same email to a supplier more than once, I would like to create a sub-process where we can validate if these "PO, Line" have already been sent to the supplier and not notify the supplier more than once for the same "PO, Line".

I created the sub-process (container #10) to accumulate all the "PO, Line" that go through this process and then relate that output with the new info to verify that there are no duplicates, but this does not work because this file is first fed with the new info.

Do you have any better ideas?

Your design seems valid, you've just got a routing issue. If you do the write to the accumulator after the join then you don't get the problem of incorrectly matching on your current set.
