GL code combinations cleanup

 There are at least a thousand account combinations that we need to turn off.

a) Is there a way to make a mass update to the table. This would be very time consuming if we had to go thru the front end and individually set the flags. We would need to set the Flags to ‘N’ on a posting level as well as a budget level. Also,we need to place an end date also.

b) If there is nothing we can do to make a mass update, is there a way to make these combinations invalid yet preserving the history.
