We used to receive input file at shared location any time between 6 to 9 AM. We have run the BOT for every half hour and check if input files are present or not ? initially at 6 AM if files are not present then it should throw email. Later again BOT will files at 6.30 AM and if files are present then then it will process it and send process end email.
After this, BOT should not throw any email of files not available for further timing i.e. 7 AM, 7.30, 8,8.30,9 AM.
How to deal with such situation and what is the best approach to implement it.
