Hello,
In FCC, u cannot have a sub structure inside a node which contains elements inside it
So, if a text file consist of multiple rows then each row will be converted into a separate XML node while doing FCC in file sender adapter.
Check sap help u will see how the sender structure will look like after doing FCC in sender adapter. So, if u want to have a hierarchical structure then u have to do some tweaking s suggested above.
Thanks
