They call it CTMRPFL (I think it's short for Control-M report flow).
You'll need to figure out where your 'newday' job is running, and what it's looking at. The newday job run every day as part of Control-M, and it reads all of the listed schedules, checks their calendar settings, and adds the jobs needed to the active jobs file.
This CTMRPFL utility simulates the first part and will list out the jobs to run in a given date range.
BMC rearranged the manuals, so you probably should just do a search in the PDF directory for that name. It's actually a procedure, and it's delivered in someHLQ.INST.PROCLIB.
