I got t开发者_如何学运维his error

ERROR: .
NOTE: The SAS System stopped processing this step because of errors.
NOTE: DATA statement used (Total process time):

Can anyone please guide me what exactly is this mean ?

It's quite straight forward; SAS has received a critical error that cannot be overcome. The output of the datastep or proceedure will not have been created and you need to debug your progam. There are many possible causes for errors.

If you need help with this specific error provide more details &/or code.
