Fabio, there is no supported way to revert successfully processed message to a status from which it can be restarted in Integration Engine. The most recommended approach would be to re-trigger interface from application level with the same data, so that new message having same payload and the one you confirmed, is produced and sent.
If that is not feasible for some reason,
- If screenshot that you provided, is taken from a PI system, you can copy payload of processed message and call Test Message functionality in PIMON of PI, submitting copied payload and interface details;
- If screenshot that you provided, is taken from an application proxy system, you can copy payload of processed message and call Test functionality in tx. SPROXY for an affected interface submitting copied payload. Ensure that you also call Trigger Commit from the menu (by default, SPROXY test functionality does not perform transaction commit).
