We have some PO's created in 2011,2012,2013,2014 for which the output message has disappeared. Client wants to see to whom from supplier side the purchase order has been sent, so they wants to see the output type in PO now. But we have checked even in NAST table where we don't have any condition record for proof (EDI, Streamserve, Mail), but client says that message type has triggered and the PO's were successfully sent to supplier.
Could you please tell me if you have any insight on where to find the trace of these missing message types? Awaiting for your reply.
