A report can have several statuses that inform you of the steps that need to be taken in order for your expenses to be processed. See below for a short explanation of all possible statuses a report can have.
A report starts on the status open, this is the status a report has when you first create it. You are able to add, edit and delete expenses in this report.
If your expense report is complete you can submit your report to your manager. You can no longer edit expenses that are in this report. If you do need to make changes you can retract the report to put the status back on 'open'.
Sometimes a report is rejected, possibly because the wrong receipts have been added. The report is returned to you so you can correct the expenses and resubmit them.
If your report is correct usually the manager will approve your report. Often there is also a second approver, this is why after the first approval the status processing is given to the report. The first approver has given their approval and forwarded your report to a second approver for final approval.
When the approver has given their final approval of your expense report. The status will turn to a green 'approved' and is likely to to be exported to your company's financial system.
The process ends when your report is closed. This means your report was approved and was processed.
