You are very close, but not 100% accurate on the creation of the Production Order.
On the SKU for the Location 2 Item, the Replenishment System will be Transfer. You will need to define a Transfer Route from Location 1 to Location 2. The Reordering Policy will determine how much quantity is on the Transfer Order.
In your example, a Fixed Reorder Policy with a Reorder Quantity of 400 and a Reorder Quantity of 200 would likely generate a Transfer for 400 (200 to get to 400 and another 200 to get beyond your Reorder point). OR You could also use a Max. Quantity policy with Reorder Point of 400 and a Max. Quantity greater than 400, which often leads to variable quantities, so use the Order Modifier to make it divisible by your Economic Order Quantity.
Now that you have a Transfer Order from Location 1 to Location 2, you need to define the Replenishment System as Prod. Order (based on your question) for Location 1 SKU. Then define what your Reordering Policy will be, which will determine the WHEN and HOW MUCH will be Produced.
In your example above, you would have been able to Transfer 200 units from Loc 1 to Loc 2 without crossing your min. quantity (a.k.a. Reorder Point) at Location 1, therefore there would be no suggestion at Location 1 for a Production Order.
I would strongly encourage you to reach out to your BC partner to discuss this further. There is a lot of flexibility within the MRP settings, so ensuring you get the parameters set correctly will help greatly with User adoption.
