You can only recall an expense that have not been approved yet. Once recalled, your approver will no longer be able to approve or reject the expense until it is resubmitted.
1. Go to My Expenses > Submitted (under the Expenses heading).
2. Tick the checkbox next to the expense(s) you'd like to recall, or click the Select All checkbox.
3. Click Actions and select Recall from the drop-down.
4. Enter a reason for the recall and click Continue.
Once recalled, the expense(s) will go back to your Draft section, where you can edit and resubmit them.
