How to recieve a PO using a code block?

Hello, I need to make a recieve for PO using a procedure. I have created a code block for this. I insert in the rcv_headers_interface and rcv_transactions_interface tables and run the RVCTP concurrent but no records are created in the rcv_shipment_headers and rcv_shipment_lines tables. Can you help me on this?
