BPCS has something similar to FrontFlushing called Allocations & BPCS does not do that very well either. I am not 100% sure of the FrontFlushing terminology ... we are so lazy (translation - management does not want to hire a team of clerks to do what the computer can do automatically for us & almost as good as humans) we eagerly jumped on BackFlushing as soon as it became available to us. What BPCS supports, if you want to use it, are transactions in which you report that you made some assembly or sub-assembly & you also had some quantity scrapped in the process & BPCS looks down the BOM for the part, which is in FMA & ELA files for SFC & JIT & concludes what raw materials must have been consumed to make whatever you reported ... so in one human action, you get: actual cost accumulated based on labor & overhead (FOD & FLT files play a role here); added to inventory receipts whatever it was that was made (good quantity); subtracted from inventory all the raw materials needed to make what you reported (good + scrap down to next level of components). The subtraction is called Back Flushing. It is the subtraction, of materials input to a step of production, from inventory at the time that the so far production output is reported to the computer. This approach simplifies the work load on humans tracking inventory activity, but it means that your total inventory for raw materials is always overstated by factory work that has not yet been reported into the computer. One reason why you might not find Flushing in BPCS documentation is that a pre-requisite to BPCS education is some ERP MRP II education & I would expect to find Flushing in the overall ERP education. That is, the folks doing documentation sometimes assume that their audience already knows the basics of the application they are trying to use BPCS to do, which I think is a bad assumption. Many people learn BPCS on the job, and the larger ERP theory later. In addition to SFC documentation, you might also look at JIT documentation.
