::Yes, but it depends on what exactly has been registered. If the production order registration is in āRegisteredā (product receipt) status, you generally canāt directly unregister it like picking or route transactions. Instead, you need to reverse it through the correction process. Go to the Production order and use the Report as finished (RAF) journal or end job process, then post a reversal or negative quantity to offset the receipt. Also make sure any related inventory transactions are reversed if needed. One thing to check is whether it was financially posted. If yes, the reversal must follow accounting rules. If serial or batch numbers are involved, the same dimensions must be used during correction. And if the production order is already ended, it may need to be reopened before making changes.
