The first step is to create the Stock Transport Order. This is similar to creating a Purchase Order. We use ME21N but specify the order type as "Stock Transp. Order". The fields we populate at the header include the Supplying Plant, Purchase Organization, Purchasing Group, and Company Code.
At the line level, we provide the Material, Quantity, Plant (which is the Receiving Plant), and the Issuing Storage Location. At the Item Detail level, we provide the appropriate confirmation control key value.

The Stock Transport Order has been created and successfully sent to the Contract Manufacturer on the SAP Business Network. In the screenshot below we highlight the Stock Transport Order number and the status.
