SE16N_BATCH is a very powerful and dangerous program. You can use it to run SE16 queries for large datasets in batch mode and later pick up the results from the spool.
But it can also be misused to fetch data that you are not authorized to see, but a batch user can see.
Good use
For example you need a lot of records from BSEG:
This might fail online. If you run it in batch mode, you can simply pick up the spool later with the needed data:
Misuse
The program can be used for hacking purposes as well. Suppose you want to get all user password hashes. SE16N for USR02 is blocked. Now run the program in batch (not with your own user, but with a batch job user with rights to read USR02 data). Now all data is available in the spool for the hacker….
