Separate WO/different Routing when Demand is from ST-OT

Hello,

We have 2 factories (2 branch). Let's say branch A and B.

Both branch can manufacture the same products.

However, some components of the BOM of these products can only be manufactured by branch A. It arrives also that, because of capacity, it cannot be produced in B during a period of time, and need temporary to be manufactured by A.

So, in these case, A transfers them to B.

We will use ST-OT to generate the transfer orders.

We have the following question:

If there is demand of 40 components in A and 10 in B.

And the inventory in A is at 0.
