is there any function like "undo" to go back to the previous status in SAS?
thanks so much!! | s******y

server and no soure code that creates the dataset, them answer will be NO as
far as I know.
2, if dataset was on the server, call IT department to restore. the server
should be archived overnight.
3. if dataset is a temp dataset, rerun the code.
don't worry, it should not be your fault. your manager should set READ-only permission to that dataset.
dataset?

maintained server or not?
easier to restore if it is in windows, dont write anything to the harddrive,
there are some restoration softwares to do that.
if in unix ,contact system admin to restore, but most likely the backedup ve
rsion from last night.
dataset?
