The documentation portal is undergoing maintenance. During this period, you can't create any new user credentials. If you do, you'll need to recreate the user credential after the maintenance period ends.
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.
