Just recently I've "Bumped" into sap.com website while looking for something....
I was surprised to see a large list of Adapters that according to SAP :
"included in SAP NetWeaver 2004."
I know the available connectivity options in the XI since XI 2.0 to PI 3.0 SP12 and
I have to say I had never seen those connectivity capabilities in the Configuration nor in SAP help.
...Off course we have our 3rd part adapter providers for VAN or AS400 etc.
But this list is new to me.
Attached is the link...please elaborate if you know anything that I don't...
