I understand the difference between rate routing and normal routing. Usually when creating a workcenter we use SAP1 key for discrete and SAP3 key for repetitive workcenters. Both the keys has setup time. But when I use MFBF, setup time is not used for calculating costs.
I also understand the reason behind this, because in REM setup time is not relevant and so setup activity is not booked. everything makes sense.
But why is setup time included in rate routing then? what is the use?
Lets say if I put some value in the routing for set up time and give capacity, scheduling and costing forumals for setup, then does that mean I can use that time only for scheduling my order and generating capacity requirements but not for costing?
