+To use the MTS + MTO rules for manufacturing on a warehouse:
+
+1. configure the warehouse to use "Pick components and then manufacture (2 steps)"
+2. Find the route "Pick components and then manufacture" of the
+   warehouse. There should be 2 rules: one to pull products from Stock and
+   bring it to PreProduction (using MTS), and one to pull products from
+   PreProduction and to bring it to Production (MTO). You need to create 2 new
+   rules:
+
+   * one route to pull products from PreProduction and bring it to Production (MTS), using the Manufacturing operation type
+   * one route to choose between MTS and MTO, with Operation Type:
+     Manufacturing, Source location PreProduction, Destination Production, MTS
+     rule: the one created in the previous step, MTO rule: the preexisting MTO
+     rule pulling from PreProduction to Production
