Inbound delivery IDoc to 3PL

Hi Experts,

We need to send out inbound delivery document through an EDI. We intend to use the inbound delivery output message to trigger to PI/PO and send out to external system. We plan to use DESADV, DELIVERY05.

Could you please explain the mandatory requirements to process the output, any BAPI required, how does the validations performed on outgoing message. A detailed steps process will be helpful. Thank you RG
