I am working on IDoc ->XI->File scenario. All things work fine. IDoc sent to XI successful, But in XI, at SXMB_MONI, this message shows up "Acknowledgment not possible", so I just open this ack message, there isn't have any error segment at left hand side, actually it's have an successful flag( black & white flag ). So finally, I login to R3 system, using WE05, I also see the ack message ALEAUD.
My question is, why the Ack status in XI is still "Acknowledgment not possible".
I paste the ACK segment of acknowledgment message in XI SXMB_MONI as following for your reference.
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
