We need to rerun an application and its JOBs.
Release : 11.4 & 12.0
Component : CA ESP WORKLOAD AUTOMATION
If the application generation is still available on APPLFILE, or "LAP appl.gen ALL" shows data, then you can use RERUNM command to rerun it, see more about RERUNM in the doc link below:
https://techdocs.broadcom.com/us/en/ca-mainframe-software/automation/ca-workload-automation-esp-edition/12-0/reference/commands/rerunm-command-rerun-multiple-jobs.html
If the application generation can't be accessed any more, then you can manually trigger the event with the same schedule date/time and other scenarios (like USER1 variable value), Be sure to use following option on "Trigger an event" panel:
REPLACE/ADD ===> ADD
TRIGGER TIME ===>
APPL on HOLD ===> Y
