After you import a new file with bulk data, a review process triggers and saves the requested changes as pending records in the Task Manager. Your MDM administrator or a user with the correct privileges, such as, a manager, must claim and approve the pending records. You cannot edit records pending for approval in the Task Manager.
All bulk import tasks trigger a batch job. The MDM administrator must configure the maximum value of a bulk import task to trigger a batch job. For example, your MDM administrator sets one thousand records as the maximum value to trigger a batch job. If you import one thousand records or more, a batch job triggers. If you import less than one thousand records, a batch job does not trigger and the records are imported instantly.
