find out when a program has been run

Hi,

To find out when a program has been run, I've developed a z program that uses FM SAPWL_STATREC_READ_FILE.

However sometimes, the FM can't read the log file, and also I've known that a program was executed but it isn't on the tables return by the SAPWL_STATREC_READ_FILE.

Can you help?

Regards,
