What is the meaning of the Expenses statuses?

The Expense submodule has three different type of status in order to track and control the expenses that are to be invoiced or to be verified. The statuses are the following:

• Draft: any expense created manually or via bulk upload with no date assigned to them. This type of expense can be deleted or edited.
• Reviewed: any expense created manually, via bulk upload or via monthly settings with an assigned date to them. This type of expense can be deleted or edited.
• Approved: any expense already assigned to an invoice. This type of expense cannot be deleted or edited.

In case of a human error, in order to delete an Approved expense, the user must remove it from the invoice it is assigned to, therefore, converting it back to status Reviewed.

Note: already confirmed invoices cannot be edited.
