idoc as sender

Hello,

Is it not that the port name in SAP XI and the RFC destination in R/3 of type 3 be of the same name, like SAP(r/3 SID) ?

Also, the RFC destination mentioned in the idx1, in XI, isnt that the same name as mentioned in the XI - sm59 R/3 destination pointing to Sender SAP System

Thanks,

Vishal
