How to generate Discrete Job automatically

for sub assembly or semi finished goods (sfg)components If we consider a BOM for parent item called : FG , and consider list of components RM1 , and SFG ( sub assembly ) . how i can generate a job automatically for SFG. Mean if an FG contain a SFG a discrete job need to fired automatically when we create a job for FG.

Can be done for CTO

Can be done for CTO environment Set lower level supply to YES in BOM Parameter

What about for noramally

What about for normally stocked finished goods. Which are not created by CTO/ATO Process ?

It occurs only in Configure

It occurs only in Configure to Order (or ATO) manufacturing environment but can give disastrous results in Make to stock …why ??? Just think the FG mfg lead time in 10 days and SA mfg lead time is 5 days So if you create a JOB for FG and then create a JOB for the SA then your total lead time would be 15 days..There are many other consequences to it. So for MTS , ETO environment the SA Jobs are taken care by the MRP
