Post Processing Lead Time for make items(Sub assemblies)

Problem Statement – there are various post production activities, such as quality control analysis, put-away and picking activities, that are not part of an item routing. Need a way to account for post processing time between backshop subassemblies.  Pre-processing lead time is the “time required to release a work order”, but once a planned order is released from ASCP, EBS is backward scheduling the work order based on the routing and the additional preprocessing lead time is not reflected in duration time (work order due date – work order start date).  If ASCP plans again after the work order is
