Job_A: dummy job. scheduled (and runs, no pre-reqs) every working day. is a pre-requisite to the job that should run "only if the previous day was a working day". the condition it puts out has current odate

Job_B: job that should run only if previous day was a working day. scheduled daily. its prerequisite condition comes from Job_A but does not use odate, instead uses previous date (PREV). should have keep active value of 0 so that it goes away during "new day" event even if it hasn't run.
