List sorting by Number doesn't work since its a string and have a prefixDescriptionIf you sort by incident number, they are no longer sorted in the correct highest to lowest (or lowest to highest) numerical order.Steps to Reproduce 1-In OOB instance, navigate to the incident list2-create a test record which has number INC9999993-create another record which has number INC10000124-Navigate back to the list view of incident 5-Click on number field to perform the sorting 6-sorting no longer works. WorkaroundThis is expected behavior and by design in all currently supported releases. For a workaround adding a zero at the starting of the number(like changing INC999999 to INC0999999) to make sure the sorting works correctly.Related Problem: PRB1345739
