Unable connect BEX through RRMX.

Hi,

I am unable to connect excel engine through RRMX.

I am getting following error message.

Connect from SAP Gateway to RFC Server failed.

Error Group

RFC_ERROR_COMMUNICATION

Message

Connect from SAP gateway to RFC server failed.

I guess this is some firewall / gateway setting.

If anybody have idea on this please suggest the solution.

Thanks in advance.

Regards,

RC
