Hi, I am currently working on an automatic data refresh using Windows Task Scheduler. Every night at midnight web scraped data will be uploaded on my computer. I will then run the automated SAS code for data manipulation purposes. However I would only like to run the SAS code on the data that is new. My file size is very large, so I would like to reduce process time by only running the code through the new data rather than the entire data set. I was wondering if there is a code that would only run on new data. Thank you!
