Month: DECEMBER-2010 (previous month of From Date). Now if DECEMBER-2010 is not available in table, then returns the
month which is available immediately the month preceeding DECEMBER-2010
Begin Date: 01/01/2011 (1st day following the month returned in output)
End Date: 31/03/2011 (last date of month based on input To Date)
Input
From Date: Null
To Date: 12/03/2011
Output
Month: First available transactionmonth in DB (say JANUARY-2010)

What is your application release?
I am in big trouble now.. can anyone help....
I have a backup of an EBS instance, lets say it was taken one month ago, and now we got some datas lost in the current production server..
some one deleted some datas...
Now we need some specific data from the old backup and restore it to the production
or can it be restored? please help me guys...What kind of data? What is the table name?
Since this is a production issue, I would suggest you log a SR.
Thanks,
