Netweaver version is 7.1
MII version is 12.1.7 build 50
The bindink key is set to XMIIIDOC automatically on each XMII IDOC resource adapter.
The IP adress is correct and there is no space issue in the program ID.
I definitely don't understand why it doesn't work. I already did the same configuration few months ago and I didn't had this kind of issue, everything was working as expected.
