Thanks Srinivas,
I will check with this & let you know.
Thanks Deepak,
I asked an ABAP'er. As I am not scheduling any jobs in the background & executing directly, they told that no spool will be generated. Hence will not be able to trace.
Also they said that if you need execute the job in background, you need to place the file in a path in application layer.
But If I am placing the file in presentation layer(I mean direct upload), i will be unable to schedule it as a job in background & hence spool will not be generated.
Please correct me in case I have told anything wrong, as I am unfamiliar with ABAP terminologies.
