Yes! This is definitely not a "save it and forget it" process. Set a monthly reminder to check that your Queries are running as expected.
Once the automated Queries are run, the "Automated Run of Scheduled Queries – Audit Report" (PRUNAQ) will appear in your DAILYxx OUTQ. Be sure to review this report.
Also remember that after CU*BASE software releases you may need to refresh your Query to adapt to changes made to the underlying database tables. Use the link below to learn how.
