Hi Kumar,
as far as I understood your problem, the Timeout error occurs when sending from
ABAP Proxy (?) to the Integratin Server, correct?
Please check with transaction SMICM on both sides the trace file and the parameter settings for the http protocol.
It could be that your message is quite large, and therefore the default values of 60 seconds are to small defined.
In general for Timeout settings, there is a nice unit called "Timeouts in XI" in the XI3.0/XI7.0 Troubleshooting Guide available at
<a href="http://service.sap.com/instguidesNW70">http://service.sap.com/instguidesNW70</a> > Operations
- Process Integration: <a href="http://Troubleshooting Guide - SAP XI 3.0/SAP NW 7.0">http://service.sap.com/~sapidb/011000358700005909032005E.PDF</a>
Extract from the guide, which should be also valid for your case:
ICM 402 timeout for http client calls (IS -> AF): ICM_HTTP_TIMEOUT
Value for all ports: icm/keep_alive_timeout (Default: 60 seconds)
Value for specific ports:
icm/server_port_0 = PROT=HTTP,PORT=<icmhttpport>, TIMEOUT=30, PROCTIMEOUT=900
PROCTIMEOUT not set > TIMEOUT is used > TIMEOUT not set >  icm/keep_alive_timeout is used
Default: TIMEOUT and PROCTIMEOUT not set –>icm/keep_alive_timeout is used
In the event of errors, increase the PROCTIMEOUT value for the HTTP/HTTPS ports used.
Do not increase icm/keep_alive_timeout or the TIMEOUT value as this would lead to a higher resource consumption.
For more information, see SAP Note 824554 - ICM timeout parameters.
Best regards,
