Can invoice line number be passed to AP invoice approval workflow

Hi Team,

We have following requirement,

If multiple lines of an invoice are matched to different POs then the approval notification should go to the PO requester for that line only. The notification should require approval for only that line from the respective requester.

Is there any way this can be achieved? For line item approval is there any way of knowing which line is being checked?

The invoice id is captured in :transactionId, but I do not see anything for the line num/id

Thanks,

Malay.
