Restarting the batch
Failed batch instances can be restarted from an earlier step in the workflow by using the administrative Batch Instance Management interface. This is faster than having to create a new batch instance. One or more batch instances can be selected and restarted from the beginning of a previous or current module.
For example, if a modification is made to a script in the workflow, restarting means that a new workflow does not need to be started to test these changes.
