I noticed an issue when I was executing the test case.
After making the "Approved Quantity" field blank and then, performing the revert, the "Approved Quantity" and "Cost" columns are still red, even though there are no errors. Please look at the attached screenshot. The occurs both for demo-data requisitions and for new ones, and on both web browsers.
Execute steps 1-10 from the test case.
After clicking the "Revert" button, the "Approved Quantity" and "Cost" columns should change color back to grey, as they're no longer blank.
