I have a bom defined with 2 operations. Each takes 10 minutes and uses a different work center. When a customer orders 50 of these products, the planner schedules all 50 of operation 1 (taking 500 minutes) followed by 50 of operation 2, meaning it takes almost 1000 minutes before the first product is ready. How do I get it to schedule them in parallel? The entire order should be complete in 510 minutes.
