PO send to vendor through e-mail
while sending the PO to vendor through e mail, some POs sent to vendor. but some are not. I have seen the in the vendor master address screen the e mail is correct.
And i have seen the messages in PO , the medium 5 (external send) is also maintained for the all POs which is sent and not sent.
So please guide in this in which part the error will be possible
Thanks in advance
