Expense reports auto-rejecting without zero dollar line.

Summary:

We've recently seen an influx of expense reports that are being auto-rejected by workflow as soon as they are submitted. There is nothing missing or wrong with the reports upon submission that would indicate a reason for the rejection. By adding a zero-dollar line item to the report, dated for the present day, we are able to get the report through workflow. We have not found a change or a reason that would cause this to happen. We typically see a few of these a month, but we've seen an alarming number of them starting around 12/16.
