Is there any method to check, how the processing of observations in the dataset is done? I mean is there any option/function to check how each step is being processed before creating dataset or output ?
Depends on what it is you want check?
If you have DMS SAS, you can run your data step in the data step debugger.
Another option is to use put statement(s) to print the contents of your variables to the SAS log.
