A sales order for subinventory "A" affects the replenishment plan created for subinventory "B"?

I have a replenishment plan at the subinventory level.
I wanna know if a sales order containing the specification of subinventory "A" affects the demand of replenishment plan created for subinventory “B”.

The point is that the client manages some subinventories by planning them with replenishmentn plan while for other subinventories it uses back to back or drop shipment.
So I would like to make sure that a sales order (with the indication of subinventory) is not considered in the replenishment plan and simultaneously create a requisition through back to back or drop shipment
