Hi Experts,
I got doubled picking lists after start the production order.
My selections when starting the production order as below:

My setup on BOM Lines

My setup on item

When i changed the setting into "Always" , D365FO only create 1 picking list. Which is correct.

Can someone help to explain? and what is the correct selection when i start and finish the production order?
Thank in advance,
Best regards,
Thu
