Deleting an ID with single row from a dataset containing multiple rows for each ID

strqimr — Thu, 25 Jan 2018 02:28:42 GMT

Hi,

I AM WORKING ON A SAS DATA SET CONTAINING 1999 IDs. MOST OF THEM CONTAINS MULTIPLE ROWS (APPROXIMATELY 100000 ROWS IN TOTAL ). THERE IS ANOTHER VARIABLE IN THE DATA SET NAMED "HISTORY" HAVING VALUES "Y" AND "N".

I WANT TO DELETE THE IDs WHO HAVE ONLY ONE ROW AND HISTORY VALUE "Y".

I AM NEW SAS USER AND COULDN'T FIGURE OUT HOW TO DO THIS. PLEASE HELP ME. ATTACHED IS A SAMPLE FILE.
