RFC_COMMUNICATE_FAILURE (to SAP)

antose — Mon, 26 Jan 2026 21:26:37 GMT

Hi!

A customers located in US have an QV Server with an existing QvSAPConnector to the SAP

Now that installation should be moved to Sweden and I'm trying to setup the installation in Sweden. When I'm trying to connect to SAP I received the following error and I'm not shore where the "error is"

Have anyone an idea what could be wrong or what we should check?

The personal that handle the firewall etc says the IP and ports are open correct.

Hi Sunil!

I use the same Client, System Number, Username and Password as they use live in USA today. The only different on my installation is the IP to the server (extern)

Do you know if anything needs to be "changed/added" on the SAP server to allow this client to access?

Hi,

Compare the hosts files from both machines, C:\Windows\system32\drivers\etc\hosts . Sometimes SAP systems are listed there.

Try also from command line "telnet machine port" to see that firewall is really opened. Black screen means OK

Than try to connect with same SAP user from other tool, and try to query same tables. It is easier to fix authorization problems from "approved" SAP tool, than start explaining what is QlikView

Dear Anders,

pls assign QTQVACCESS role to qlikview user created in SAP to extract data from SAP.

It seems you are missing Data files for the transports. Please make sure you unzip the transport contents and place Kxx file under user/sap/trans/cofiles folder (or something like it based on your SAP directories) adn Rxxx file under /user/sap/trans/data folder. Then repeat tp addtobuffer and see how it goes.

Rakesh,

After the previous error message we tried with QV SAP Connector 5.40.
we face this new error message.

I have requested my SAP team to do as you suggested. Once they are done, i will get back to you.
If you have any suggestion, i'm pleased to try.

Thanks for Quick Reply.

Dear Srini,

As per your posted screen shots . it clear that tranposrt is not sended properly.

pls send both transport once again. it will just overwrite the existing one .

We use SAP BASIS 7.00 and SAP QVC 5.40

Are these your transports which you imported in SAP?

Normal 0 21 false false false DE X-NONE X-NONE MicrosoftInternetExplorer4

1.1.1 SAP BASIS system 6.40 and 7.00

For these systems, the following transports should be installed on the SAP System:

1) E6DK900064 (Data extraction)

2) E6DK900051 (User profile)

The transports must be installed in the above order. The first is cross-client; the second transport is client-specific and has to be installed in all clients where it is intended to be used.

If these are the transports and still it is not working? Then the transports are not installed in the above order.

Bestthing you can do is import the transports correctly in the above order.It must overwrite the existing ones.

Sravan

Hi Sunil,

No, not yet.
I'm still waiting for their reply. Thery are located in US, hence the time gap.
Before using Qlikview connector, should i test with Std GUI?.
I'm still facing the RFC Communcation Failure problem and i hope he face transporter installation Problem.

Do you have any documentation for Configuring/Administration for SAP system, which can help me.

Srini.

Can I know whether SAP Basis person assigned required authorization to qlikview user id through which you are extracting data.?.

He created a seperate user to access the SAP and given that credentials to me.
But in documentation, they have mentioned QV user should be provided QTQVCACCESS. Unless we install the transporter in SAP system, we can't able to create the user with the role.

First i can't able to connect the SAP system. I get this RFC problem.

Hi,

how many network cards u have on your qlikview server? If you have more than one and one of them are disabled, then you need to check the order of those network cards.

it seems there is a problem with the communication of QV and sap system..

one more thing is that, from my previous expirences, may be the version of SAP's librfc32.dll is older. keep this option also in your mind.

Is there any problem in this access method?
