proc sort

By mistake without using out statement i have modified existing data set, Is there any possibility for retrieving the previous data set

No. PROC SORT Replaces the exitsting data set if you do not specify the OUT= Option.

Only from the last backup.

If you did not do anything that removes information (nodupkey, drop columns), and you know the previous sort order, you can re-sort it to that.
