HTTP - RFC problem...

Hi guys,

I'm having the following scenario,

1) HTTP -> XI-> RFC

2)RFC -> XI -> HTTP

Meaning, I'm trying to send a XML file by HTTP which will then be read by a call to a RFC. This RFC will then return a ok_code which will then be sent by HTTP.

The problem is: How do I know that the HTTP was able to send the file?

Where can i see if there is any error or even if the RFC function was executed?

Is there any transaction which enables me to monitor the process?

In the RWB monitoring i didn't found any tool which could help me...

Please guys, it's an urgent problem...

Thank you all in advance
