Repair is work done on a completed item. Whilst repair is the word that is normally used, strictly speaking, it is also rework if it is considered to be a quality loss, i.e., repair and rework. 

Rework and repair are similar except that rework is done on an item in WIP. Rework is time considered to be a quality loss. Work that is done on a completed item is usually a quality loss, although you can have a repair that isn't a quality loss. For example, a service performed on a completed item. Under that circumstance, we'd create a repair workflow but the operations wouldn't be marked as rework operations.

The two ways to spawn a repair task are Start Schedule Repair and Start Manual Repair.

Start Schedule Existing

You have a job to start the repair and you add the item you want to repair to the job (start node - Start Schedule Existing). This could be for an item that was returned for a repair. You want to schedule a job to repair it and you want to execute a workflow. The Start Scheduled Existing workflow would look for an existing item to work on rather than creating a new inventory item.

After you created the start node, you will need to add one of more operations.

Process for starting a repair:

1. Navigate to the Schedule Manager screen.
2. Pick a job that has a Start Schedule Existing to open the Job Serial Numbers screen.
3. In the Add Serial Numbers screen, you can click the Add Repair Serial Number which searches for an existing item to repair

Start Manual Repair

Process for starting a manual repair:

1. Open the Item Status screen and search for the item.
2. Click the New Task button to open the Choose New Task Visit which launches the repair job. It creates an asynchronous task.
