Hi Shaik

Have you taken a look at the file %windir%\system32\drivers\etc\services?

If you haven't, try and find the line sapms<sid>, where sid is de SID of the system you-re trying to reach.

If the line isn't there write it down like this.

sapms<sid> 36<nr>/tcp

That works for me.

Hi Bhasa,

Get more information about the function module exception from the JCo exception text and the SAP system data from the calling application or the JCo traces; if the exception was thrown on the ABAP side, check the function module or BAPI in transaction SE37 or SE80.

and have a look at the dev_jrfc.trc files. These files are written by JRFC and can be found in the directories j2ee/cluster/server* of the J2EE Application Server Installation.

Hi,

go thru this link

it might helps your.

Generally it comes

JCO_ERROR_COMMUNICATION

Exception caused by network problems, connection breakdowns, gateway problems, unavailability of the remote SAP system, etc.

get the host of the SAP System from dev_jrfc.trc or the JRFC trace; ping the SAP system from command line; check routers, gateways, SAP systems

Thanks
