PO creation when transfering shipment cost document

Hello,

when I transfer a SCD item, the system checks if a PO already exists and if not creates this PO.

my question is: where do I define the document type of this PO???

with transaction T_53, for each TPPt/Shipment cost type, I define the Purch org, the purch group and the plant for the PO but NO PO TYPE!

thanks for your help!

Best regards,
