Exporting items is different from producing items in the following ways:
After you have exported an item, you can change the mark or status that you have assigned to it. However, after you have produced an item, you cannot mark it or change its status (but you can still display it in the Review pane). If the same item has been captured in another case, its status in that case remains unaffected.
You do not have to wait until the end of the reviewing process to carry out production; you can produce the items that you have reviewed at any time. You can then carry out productions of further items later, after they have been reviewed. If you use the same output folder and production run name for multiple runs, Discovery Accelerator overwrites the report summary each time.
If you carry out a production run and then something goes wrong with the files that you have produced - for example, they are accidentally deleted - you can reproduce the items. However, once you have successfully produced items, you cannot undo the process.
