The only reason that I'm not using this approach is that it's not merging similar manufacturing orders, if I create sale order of 2 Boats and 5 Dashboards (yes I can sell dashboards separetly) , the system will create 3 manufacturing orders : 2 boats , 2 Dashboards , 5 Dashboards. From a manufacturing perspective, I should see 2 MOs only: 2 boats , 7 Dashboards. This is not possible with Just in time scheduler as I found out, but it's working if I use reordering rules, the problem is I have to click 2 times on "run reordering rules" to generate 2 MOs as in the example here which is annoying
