BEx RFC_ERROR_COMMUNICATION

[Former Member]

Dear all,

I got a funny issue when I connect to BW server in BEx. The 'Connect to SAP gateway failed' is poped up, the fun is I can connect to the same BW system via SAP GUI. I checked all the parameters for BEx, Macro,security and even the service configuration in my system. The error message likes:

Error Group:RFC_ERROR_COMMUNICATION

Error:converting to/from net format failed

Message:Connect to SAP gateway failed

Does anyone got the same issue? Or some guys know how to fix this issue.Any sugguestion are appreciated.

<b>Reason and Prerequisites</b>

The SAP gateway host is deactivated or the TCP/IP port 33xx (where xx corresponds to the system number) is not open.

<b>Solution</b>

Issue statement ping <IP address> (In this example:192.168.4.2) No reply: Boot SAP Gateway host required.

An answer:Check whether the TCP/IP port 33xx is open (where xx corresponds to the system number) and start the SAP gateway.

The TCP/IP port is also partially defined in the services file as an sapgw<SID> or sapgwxx entry (where xx corresponds to the system number). The services file is in the Windows directory or in WinNT/System32/drivers/etc.

Note 447882 - RFC_ERROR_COMMUNICATION BEx Analyzer: no back end connection

Hope it Helps

Hi Chetan,

Thank you for your reply.

I checked with the notes you mentioned before I post this question here. It dosen't work.

Only one machine occurs this issue, the other machines in the same gateway work well.This is the confusing.

Hi Gerald

I have several machine with the same problem.

The machine with problem can connect the BW using SAP GUI

but can't connect the BW using BEx Analyzer.

Some machine can connect the BW server using BEx analyzer.

Did you solve the problem??

Please let me know that.
