I'm quite new to SAS and really can't get my head around it's code, so asking here for help.
I've a job that is reading an external csv file, and have a macro created by a colleague that validates the data in this external file and prints out error message to a work table.
What I'd like to do is either on precode of the file reader, or by using another user written code transformation is to read the work table and check if observations exist, and if they do, abort the job. From googling, and between here and SAS community, I can find how to read a dataset and count observations but I'm having real difficulty in figuring out how to implement it so any guidance would be really appreciated
Can anyone please help me on this?
Thanks
