Unable to disable AD accounts from One Identity Manager


I am trying to get the status of the user from CSV file and setting "IsTemporaryDeactivated" as True. But when IsTemporaryDeactivated is set to True from csv, it is not able to update AD account. And when I directly change IsTemporaryDeactivated to True from Manager tool, it is able to update AD account. What can be the reason? how this can be resolved? Please help. Thank you.
