Connection Integration Server failed. Status: HTTP/1.0 401 Unauthorized

[Former Member]

Hello everybody,

I know, that this topic is discuss several times, but I couldn't find a satisfied solution. Sorry for the questions again.

Question:

Scenario: We have to realize a proxy connection between BW 3.5 and SAP XI 3.0. SLDCHECK works fine. But we have trouble with the http - Connection. We create a destionation via TA SM59:

. Target Host : Hostname SAP XI Integration Server

- Service No: <Port>

- Path Prefix: /sap/xi/engine?type=entry

- User: XIAPPLUSER

(this destionation works fine in another Sender systems)

If we try to test the connection. We get an Logon Prompt for the SAP XI Web Application Server back. Funny is, if we put the same User / Password from SM59 in, we get no error message back. But we couldn't put any logon / user information in the proxy area. What can we do ?

I did/checked follow:

- SAP XI: The User XIAPPLUSER, has the right password and authorizations,

- SAP BW: The Destionation is created and the System - Role (sxmb_adm) ist maintained.

- SAP BW: we compare the configuration with other Sender - Systems

- SAP BW: we create the Destionation with RFC - Typ H

Remark:

I created the same Destionation in other Sender-Systems: Works fine, we didn't get any logon promp, if we test the http Destination via SM59.

Thanks for your help

Stephan,

I am not sure, I got your problem. Is it asking for User Id, Pwd when you test the connection? What happens if you give the XI server user Id password?

Do clarify. We faced a very similar scenario a few days back and resolved it.

Hello Jai,

yes, its asking for user ID and Password when I did the test connection in SM59.If I fill the user and password, I get no error back. Do you now a way to help my ?

Remark:

I use the same user/password which I wrote into the tab LOGON/Security by the RFC-Dest.

I assume you are getting result HTTP500 code.

If so, delete your RFC connection and re-create a new one. Remember you press <enter> only once during the creation of RFC connection ie after selecting the Type as H. Also press save immediately after entering userid and password.

Also create the user Id with password in CAPS

Eg: Id: XIAPPL

Pwd: TEST

Hello Jai,

crazy, now is all ok. Thanks indeed. But I can't understand the procedure to create a RFC Connection.

I also recommend you to check the ABAP proxie section of the blog /people/sravya.talanki2/blog/2006/12/27/aspirant-to-learn-sap-xiyou-won-the-jackpot-if-you-read-this-part-iii that contains most of the Info.

Try the report SPROX_CHECK_IFR_ADDRESS on both backends, the report will help you to detect the differences.

Hello Sandro,

I execute the report, but the solution was in both systems the same:

Result:

In Exchange Profile: http:<hostname:Port>/rep

In Table SPROXSET : <blank>

Status: OK: Address maintained

I also tried follow reports:

SPROX_CHECK_IFR_CONNECTION

Result: Integration Builder server functioning correctly. Data unterstood

SPROX_CHECK_HTTP_COMMUNICATION

Result: HTTP communication functioning

SPROX_CHECK_IFR_RESPONSE

Result: I get a list of xml - entries back

Remark:

I thought the cache information was obsolete. I start a full cache refresh on SAP XI site, without success.

Remark 2:

I checked the system area, and I found out, that the Sender System with the problem is a non UNICODE and our SAP XI is a Unicode. Is this a reason, we have a http connection problem ? And when yes, what can we do.....

Thanks

Please clearify if you have problem with SPROXY of with message exchanges.
