+Notes: 
+PO Number editing
+This feature is provided primarily in cases where imported data has unwanted PO numbers that need to be re-assigned to other numbers. (some v7 users with Microsoft SQL server had numbers jump into high ranges due to a SQL server bug)
+Normally you would never change these numbers, just let the system handle it automatically
+BizAdmin role can edit the PO number, however it doesn't change the auto po number generator next value, so, for example if the last generated number was 10 and an existing po is edited to change the number from 7 to 11; when the next new PO is made, it will be automatically assigned number 11 and there will then be two number 11's.
+To avoid this use this feature of editing PO numbers in conjunction with the reset serial number feature under global settings to ensure no duplicates.
+i.e. lets say you have the last po number auto generated is 10, you could reset the auto generated number to 20 to free up a block of 10 numbers to use on existing po's.
