When an expense item has been Submitted, it is pending approval from a specific user (the "Assignee"), as determined by the logic implemented in your Nexonia configuration. The user who submitted the expense item no longer has the ability to edit or delete the expense item.
As an Administrator, you can enable functionality to allow users to Recall expense items if they submitted expenses in error or need to make changes. Recalling an expense item changes the status from Submitted to Draft.
To enable this feature, go to Settings > Company > Features > Edit > Expense Reports > Select “Allow user to recall a report after submitting” > Apply.
Enabling this feature also enables email notifications. The email notifications will be sent to the current Assignee and prior approvers immediately when expense are recalled. If these notifications are not desired, they can be modified from Settings > Company > Notifications > Edit > Expense Approval Workflow.
To learn how to recall expenses once the feature is enabled, refer to the article "Recalling Submitted Expense Items".
