3. Activate 'Multi-Step Routes' in inventory configuration
4. Go to 'Warehouse' and select 3 steps route in 'Incoming Shipments' and
'Manufacture' and save
5. Go to 'mrp' and create a new BOM
6. Go to 'purchase' and create a PO with the same product in BOM and confirm it
7. Click on smart button 'Receipt' -> 'set quantities' -> 'validate'
8. Go to 'mrp' and create a MO with same BOM change the 'Scheduled Date' and
confirm it
9. Click on smart button 'Overview'

Trace-back will be generated.
