EDI uses “Functional Acknowledgements” for this.
X: Send ‘n’ POs with unique IDs.
Y: Got these POs: {…}
X: Reconcile Y’s list with the original list.
X: Escalate missing IDs to administrator.
I believe version 6 of the EDI for TN adapter provides a level of reconciliation in that it will mark the outbound docs with an indicator that an ack was received. For docs with no ack indicator, you’ll likely need to write something to identify those.
For previous versions of the adapter, you get to do all the work yourself. Same for non-EDI traffic (I’m not aware of any other adapters/components that perform reconciliation–please chime in if you know of one).
All of this would happen “on the fly” rather than “on demand” as you’re asking about.
Not sure this info is helpful but thought I’d toss it out there anyway.
