the topic is very difficult in MTS because you do not have a specific tolerance per pegging arc.
Pleasse have a look at the following SAP notes:
1250779 Underdelivery tolerance at component level
875667 Underdelivery tolerance in the SAP_PP_003 heuristic
663313 Implementingunderdelivery tolerances from SO as of APO 4.0
