Not all BPCS jobs must be run in a single threaded JOBQ.  I could by no means 
offer a definitive list, as it would vary by installed options, 
modifications, and release levels.  However, my current primary client runs 
everything except MRP/CAP generation in multi-threaded JOBQs.  The rule of 
thumb would be to test in a seperate environment and see what works and what 
doesn't.  Anything with a suffix of 200 should be pretty safe...
