what data passed?
What are the different ways to find out what data has passed from sender to receiver system (xi inbetween) at each field level?
The data passed can be monitored in XI by the help of transaction SXMB_MONI or SXI_MONITOR .
if your data has reached to xi you can check the payload of that message which would contain that data .
Another way of checking the data is in RWB . there you can got to the mesage monitoring tab and can check the payload of tht data .
