Open PO report showing "Sent" or "Not Yet Sent"

Question

Can someone direct me to the T-Code for a report that shows what POS have been sent to the supplier and which ones have not?
Thanks for any help you can give me.

Answer 1

there is no such report in SAP, you have to develope it yourself
in ME9F you can do the message output, here you can select according to processing status
you can only know whether a message was created and outputted, but not whether it was sent.
Sending is something a subsystem or a human does. this activity is not recorded in the PO.
if you fax a PO message out of SAP. then the green light in the PO next to the message just tells you that SAP has succesfully given the message to the fax server. but it does not tell you whether the fax was successfully send. this can be found e.g. in SOST transaction.
