Planned order creation for another plant

I have 3 plants 1, 2 and 3.

I receive forecast in plant 1. Convert it to PIR in plant 1, and run MRP for plant1.

Plant 2 is the supplier plant for Plant 1, but it is not manufacturing.

Plant 3 is the production plant which supplies to plant 2 and plant 2 gives to plant 1.

How can i automatically create planned orders in both plant 2 and plant 3 directly from plant 1 through MRP.

Also I need to do this without Special Procurement type.
