Control of PR or Production order for planned order created after MRP execution

[Kazu]

Hi expert,

Here is an MTO scenario like this.

(1) A certain Material is produced in multiple factories/plants. there is only one Material Code.

(2) An order is received from a Customer. There is only one shipping plant. Let's call it Plant A.

(3) Run MRP and create a planned order which will be converted to Production Order at Plant B for the specific order and STO to Plant
A. For another order, create a Purchase requisition from Plant C to Plant A.
* Assume that there is always plenty of inventory at Plant C.

I believe a Planned Order is created when MRP is executed for a sales order.
I just want to clarify here, is it possible to specify Production Order or Purchase requisition for a specific order or a specific Planned Order?

Thanks.
