Hi,

The issue is only with the re assignation of the pending review expense reports: if an expense report is pending review (that means the initial auditor took an action like for ex: rejected/returned it), then it goes back to same auditor. No other auditor can assign this expense report to himself.

So, in case of the initial auditor's absence, the expense report cannot be reviewed again. This should be possible. Another auditor should be able to assign the report to himself. Now, the Assign button is greyed out in this case.
