BEx RFC_ERROR_COMMUNICATION

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.R
Gerald

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

However, logging on to BW using the SAP logon-pad I can connect without having an issue.
This login issue through BEx is keep repeating. Some times it will work and some times it will throu the above error. But, never had prob to login through GUI.
Appreciate if you can help me to understand why is is happening and provide some permanent solution for this.
Thanks,
Kiran

Hi Laszlo,
Pls find my respoce to your questions as below.
When do you receive this error. Do you get it also when you open Analyzer from Start menu?
Iam facing this error when i access BEx Analyzer from srat menu and then clik on connect button in Excel and provide login details and then finally facing this error.
Have you checked your frontend installation? Is it all right?
iam able to connect to the same system through login pad, so i think everything is ok with front end.
Iam not sure...weather i answered ur question or not.
The same error persists for 70 and 35 Analyzer as well?
i have only 7.01 environemnt, where iam facing this error. we dont have 35 analyzer.
Plese let me know, if you have some inputs or solution for me.
Thanks...Kiran

RFC_ERROR_COMMUNICATION on BEx

Hi
I'm working with the BW system and I'm new to BEx reporting, I practiced with the BEx Analyzer before a change in IP's and it worked well, after that change (I suppose), the SAP GUI couldn't connect to the BW server and threw me the following message:

hi,
192.168.117.25 is the new IP ? do you use IP address in your sap logon pad or hostname/servername ? do you maintain the IP mapping in 'host' file ? changed accordingly ?
also try to search if there are 2 'saplogon.ini' file, maybe the one with IP updated not used by BEx, try to overwrite with the latest one. normaly located in windows folder and program files\... \frontend ...

SSO (SNC) for BEx applications

In our testing environment, we use SSO(SNC) through the SAP GUI for Windows to access our backend systems:
*SSO file gx64ntlm on the server side
*SSO file sncgss32.dll on the client side
*User mapping (SNC tab) mapped to active directory user
and everything works fine.
However, when launch BEx Analyzer, Query Designer, etc, we get the following error when accessing the SSO logon options in the SAP Logon Control tool:

Remote -Bex analyzer not working

Hello experts,
I am getting Bex analyzer error while running Query from Remote.
RFC_ERROR_COMMUNICATION.In the detail screen, the system displays message "Partner not reached"
Thanks for your help

Hello
Here is some analysis,let me know if you face any problems.
Issue statement ping <IP address> (In this example:192.168.4.2)
Result - No reply: Boot SAP Gateway host required.
Solution - Ceck 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.

Windows 7 64 bit giving BEx Problems. Big time problems (!!)

Hi there, i just got through an issue with BEx connecting to SAP on a laptop using Windows 7. After googling and sdning and SAP noting for a while did not find any suitable answer to this issue which seems strange to me as Windows 7 64 bit is not really a brand new product. The full specs are as follow. Anyone bringing some light into this subject would be very much appreciatted.
=> SAP Logon 720 with 0 Patch Level.
=> MS Office 2007
=> Windows 7 64 bits
In C:\Windows i got:
     -> SAPMSG.ini
     -> Saproute.ini
     -> saplogon.ini
in C:\Users\username\AppData\Roaming\SAP\Common i got:
     -> Sapgrph
     -> saplogon
     -> SapLogonTree.xml
     -> saprules.xml
     -> Saproute
     -> services
The issue is that i am not able to logon either via BEx 7.x or 3.x. The Error message is:

Hi Alex ,
SAP GUI for Windows 7.20 and all related applications including SAP Desktop Office Integration / BI Frontend / BW Frontend do not support Office 2010 64bit, only 32bit versions of Office are supported.
This means that when using 64bit operating sytems with SAP GUI for Windows and related components you have to use a 32bit Microsoft Office version .
For your issue , you can check these Notes.
1. 1442028 - SAP GUI for Windows 7.20: No support for Office 2010 64bit
2. 1264857 -   BExAnalyzer 7.X does not work on 64 bit Windows PCs

Not able to execute Query in BEx Netweaver 2004s

Hello Experts,
I'm trying to execute query on the web from BEx Netweaver 2004s.
But I get this message:
The page you are looking for might have been removed or had its name changed.
And the wired thing is I don't get host and port number in the address bar.
http:///irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fcom.sap.pct!2fplatform_add_ons!2fcom.sap.ip.bi!2fiViews!2fcom.sap.ip.bi.bex?QUERY=0CCA_C03_Q1000&VARIABLE_SCREEN=X&DUMMY=1
But when I execute query from BEx 3.x it works.
What settings should I check and make so that it works fine in the new version.
One of the parameter icm/server_port_0 has a timeout limit set to 150.
Thanks in advance.

Thanks All of you but no luck as of now.
While manually adding host and port into the address bar i got this message:
The initial exception that caused the request to fail, was:

BEX - Query Designer - Query Execution - IE "The page cannot be displayed'

Hi ALL,
Trying to execute a query from BEx Query Designer, result needs to be displayed on Internet Explorer.
However, when IE pops up to show the result, it says 'The page cannot be displayed'.
It seems the PORT Number is wrong.
When I execute the RSPLAN the port number is 52300 (23 ASCS) (and it works!!).
For this web query the port in URL is 55300 (53 SCS).
Could you help to configure the right port?
Something needs to be done on Basis side configurations?
Thank you,
Nivia

Hi,
This especific problem was solved na SM30 programa RSPOR_T_PORTAL.
But I still have problem:

I have looked the services and hosts and the files has the sapgw<> and sapms<> right configured.
The important detail is that The PORTAL works if it doesn't come from BEx.
COULD SOMEONE HELP ME?

When we see this at our sites it's normally because the Bex hasn;t been upgraded and is still sort of using a 6.4 gui
When you are loggin in via sapgui you go in on a 7 gui - and it accepts a password > 8 chars
Then when you login via bex designer/analyser it pops up with a screen that is 6.4 and it cuts the password to 8 chars - hence rfc errors or password errors
We normally get our local in country IT teams to reinstall Bex to the latest version

"Connect to SAP gateway failed" error message when we connecting bex to bw

any one can help in connecting bex with BW.
we got a error when we are trying to connect bex to bw from offshore. as we do not have basis consultant we only need to connect bex with BW.
"Connect to SAP gateway failed".
RFC_ERROR_COMMUNICATION
But it is working properly connecting to onsite team.
this is the first time we are connecting from offshore.

You didnt answer the first question of when exactly are you getting this error message - during direct logon to BEx or using transaction RRMX. Anyways, I assume both are giving the error.
Check how the SAP logon pad is configured to access the BW server currently.
In our case the problem was resolved by using the server machine name instead of the IP address to logon to the BW server.
If you are currently using the IP address in the logon pad then change it to the server machine name instead.
Also, make this entry in your hosts file (windows>system32>drivers>etc>hosts) add an entry like:
<IP Address> <bw_server_machine_name>
save the file, reboot the system and then try logging onto BEx again.
If it still does not work - send me screenshots of the logon pad configuration you have for the BW server.
Hope this helps,
Regards,
Nikhil
