When a manufactured item is reported as finished, the system registers the item as available for further physical processing (such as shipment or putaway) and also makes related postings to one or more journals. This feature lets you control whether items should be registered as physically available before or after the related journal postings are fully processed. If you choose to defer the journal postings, then physical availability won't be impacted by these and other related processes. Without this feature, the system always completes related journal postings before registering a finished item as physically available. This feature depends on the "Message processor" batch job, so after enabling the feature, set up the required batch job by going to System administration > Message processor > Message processor.
