Connection test for connectors(SAP R3 system) fail

Hi,
I got an EP system and connected to one existing R/3 system.For the same i have defined it in system landscape of EP.System administration ---> system configuration ---> system landscape.In property editor i have deined all the min required properties.
Application Host       172.16.3.68
Gateway Host            172.16.3.68
Gateway Service        sapgw00
Logical System Name    ISCCLNT100
Remote Host Type       3
SAP Client            100
SAP System ID (SID)    ISC
SAP System Number      00
Server Port            3200
System Type            SAP_R3
Trace Mode             1
The system intially works fine.But when
1)There are more users it gives connection error.
2)If there are not much users then also After some time it automatically shows connection error.
Then when I do Connection Test for Connectors,it shows "X" failed.
What I usally try to do,I restart the SQL server.
But this method does not work.I have to restart the EP.Then again the system works fine.
I think there are something wrong input in the property value of SAP R3 object setting.
Hey folks can u please help me in sorting out this problem?Why such connection error happens again and again?

Hi Rajeev,
Thanks for your answer.Actaully I have miss interpreted the problem.Sorry Problem is not with in the SAP R3.
Connection problem is like this::
I have defined a system EPSQL(system alias for MS SQL sever DB) for my EP instance
To connect to database.
The connection tests to the alias is ok.
But as more and more users try connecting to the db the connection test fails.
Restarting the SQL server doesnt help.
I have to restart the EP instance to get over the problem
I think there are something wrong input in the property value of object setting.or,EP maintains some timeout or max user info...
Do u have any solution?

Portal connection test for connector giving error.

Hi All,
In the portal ,
No connection to system SAP_BW found:
com.sapportals.connector.connection.ConnectionFailedException: Connection Failed: A nested exception occurred. Could not initialize physical connection.
Connection Failed: A nested exception occurred. Could not initialize physical connection.
Connection Failed: A nested exception occurred. Could not create JCO connection.
No RFC authorization for function module RFCPING.
Can somebody help in this.
Thanks

But the message is pretty clear - "No RFC authorization for function module RFCPING." Assign authorization for mapped user (or current user in case of SSO)

Connection to ECC with SAP Logon Group failing

I'm creating a new system connection to an ECC backend using a logon group (transaction SMLG in ABAP stack). I have created the connection with the wizard as a SAP_R3_LoadBalancing connection and given it the appropriate Group, Logical System Name, Message Server, Remote Host Tppe and SAP Client. Also I've given it an Alias.
SSO is working correctly between the portal and ECC.
The System Connection Tests > Connection Test for Connectors works, as can been seen::
Test Connection with Connector
Test Details:
The test consists of the following steps:
1. Retrieve the default alias of the system
2. Check the connection to the backend application using the connector defined in this system object
Results
Retrieval of default alias successful
Connection successful
However, if I try to connection to this system with the Alias, it fails. If I change the alias to a system with a standard R3 connection with a specified hostname, it works. The /etc/services is correct and contains the appropriate entries. Any ideas?

Hi Srikishan,
Thanks for the response. When user from CRM logged in another language than EN for eg. FR, clicks on external link in CRM, takes to EN, only if that language FR is not installed in ECC, else it will take to the same language in which CRM user logged in. This cannot be controlled in SSO configuration. Is this correct?
In case if FR is installed in both the systems, ie CRM and ECC, but user wants to log only to EN when clicked the external link(to ECC) from CRM, how we can configure this, Is any parameter can control or SSO setup configuration available? Please advice.

What is the best approach to capture TBOM's for a SAP SRM system/functionality?

Hello SCN Community,
It would be much appreciated if somebody could share some information about the following....
What is the best approach to create TBOM's for a SAP SRM system? The SRM functionality is basically consisting out of multiple ABAP Web Dynpro's that are connected as a process via a SAP Portal (as is understand it). The entrypint to the SRM functionality is via the SAP Portal.
Do I first have to create a link to the Portal via an SAP Web Application link in SOLAR01 and then start recording? Will it record only the portal objects or also the ABAP Web Dynpro objects?
Do I have to list all the separate ABAP Web Dynpro's in SOLAR01 and use those as a starting point?
I am myself more familair with more classical SAP ABAP ECC systems and transactions. I could hardly find any information on the use of BPCA and the required TBOM's in the area of SRM.... Any help would be much appreciated!
Kind Regards,
Guido Jacobs

Hi Guido,
today was a new blog released, maybe this helps:

Error during connection test for Content Producers in FPN

Hi,
I have a question regarding connection test for content producers in FPN. Please let me explain the scenario,
The portal server (PS1) is in the network domain say "XYZ.com" and we are accessing the portal from different domain say "ABC.com" via browser. We need to configure another portal (PS2) which is in the network domain say "mno.XYZ.com" with PS1 using FPN. We have imported the certificates of portal PS1 (consumer) in PS2 (producer) portal server and done the required trust configurations using VA in PS2 portal server.
Then we created a new content producer object for the PS2 portal (producer) in PS1 portal. But when we did the "Connection Tests" it gets failed with the following error message,
"Could not retrieve the WSDL file; the handshake URL may not exist or may be invalid".
Can any one please tell me why this error message is coming. Is it due to any network connection issue?
Thanks,
Gokul.

Hi Ginger,
somehow, yes :-) I deployed the iFlow for customer master replication. After creating a customer the trace looked different and terminated at the reverse proxy. So the simple connect somehow is not able to do the same...

For Connect MS-Access to SAP - XI System , what Driver is required?

Hi all ,
There is a requirement to connect Microsoft ACCESS Database from SAP XI System. To achieve such scenario first basis needs to deploy the required vendors Database Driver on SAP XI System.
So Please tell me what drivers need to deply for Microsoft ACCESS DB Drivers on XI System , to achieve such scenario.
I am following a document whose name is How To Configure External Drivers for the JDBC & JMS Adapters.
MY PI System is PI 7.0 and on Windows Server 2003 standard x64 Edition.
MS-ACCESS is on normal PC with XP on it
Regards
PS

Hi,
What’s the error message you got? It seems that you haven’t install the correct driver for access the .xlsx file. Please download and install 2007 Office System Driver: Data Connectivity Components from below link to check the issue again:
http://www.microsoft.com/download/en/confirmation.aspx?id=23734
Besides, to change a .xlsx file to .xls file, we should open the .xlsx file, then click ‘Save As’ button under File pane, and then select the appropriate location and ‘Excel 97-2003 Woekbook(*.xls)’ as type for the file. Then we directly use the new .xls
file as the source in SSIS.

XI testing for two SAP R/3 systems with same system id/logical system

Hi
We are currently in the process of upgrading our R/3 4.7 to ECC 6.0 and plan to maintain dual landscape for DEV & QA (4.7 & ECC 6.0) for a period for testing and maintaining existing applications for fixes etc. The second DEV & QA (upgraded to ECC 6.0) are copy of respective systems and these systems are created automatically under technical systems in SLD by auto update (RZ70).
The question is, can we use the same XI system for testing inbound/outbound interfaces for both the systems i.e 4.7 & ECC 6.0 at the same time. I am aware of the fact that XI Technical/Business sytems dependent on unique logical systems, so we cannot create new business system for the upgraded DEV-II ECC 6.0 system.
For your information, we have two slds (one for XID/XIQ and second one for XIP).
What are the options without disturbing & maintaining the current XI system set up?
1) Can we change current Business systems e.g DEV010 to use new technical system i.e DEV-II ECC 6.0 for testing for a period and switch it back to DEV-I 4.7 technical system?
2) or change logitical system name of DEV-II ECC 6.0 and create new business sytem in SLD without interfering the existing setup and modify/create interfaces to use this new business system?
3) Do we need to refresh cache from time to time in XI ?
4) Any other implications
We will be upgrading XI to PI 7.1 after ECC 6. 0 Upgrade.
Any views on this would be highly appreciated.
Regards
Chandu

Hi
Technical System was created in the SLD automatically after RZ70 configuration in the new DEV-II system. We then modified Business System to use the new Technical system and carried out following steps:
1)     Original Idoc metadata was deleted from XID
2)     The port definition was deleted
3)     A new port definition was created for new system
4)     The metadata for each idoc type used was re-created in IDX2 , using METADATA -> CREATE
5)     This brought in all known versions of the idoc segments, including the 7.1 version.
I have already checked the guides suggested for our upgrade and we are thinking of going ahead with fresh installation and migrating the interfaces.

Chandu

Create SAP Source System Failed

Hi all,
We are using NetWeaver 2004s BI and try to connect to ECC 5.0. I tried to create SAP source system but got error message saying "RFC user logon failed". When I check RFC destination in ECC 5.0 for BI, the test connection is ok, but the remote logon will pop up another logon screen asking for id and password. I am pretty sure that the id and password in RFC destination is correct. The RFC destination in BI is ok. Can you help me out with this? Thanks a lot in advance.

Hi,
Check the Default Logon Client for ECC 5.0
and verifiy that the User is in the Same Client
Each RFC destination has a mapped user for specific Client..Check the Client and User in the same client

Hi!
Many thanks for your answer.
Via BD87 on BW system I detect that all the IDOC's (type: RSRQST) will be received from SAP ECC system.
Via tcode SM58 I could not detect any entries.
However the loading status from yesterday is set to "red".
The errors are:

BI Administrator for several SAP BI systems within SAP Portal

Hi!
I have activated BI Administrator function in SAP BI system and in SAP Solution Manager system as well.
I have connected both systems to SAP Portal as SAP_BW systems.
Per default I can see in SAP EP --> BI Administrator only the SAP BI system entry.
I have the following problem:
When I assign system alias "SAP_BW" in Portal for one of the systems I can see this system in drop down list on BI Administrator. BUT I can assign this system alias only for one system.
Is there a work around to solve my problem?
How can I see the SAP Solution Manager systen in drop down list within SAP EP --> BI Administrator?
Thank you very much!
regards
Jürgen

Function Module to perform authorization and connect test for given RFC

Hello Experts,
I am working on request, which requires checking the RFC status.ie whether both Connection Test and Authorization test is OK for a given RFC.
Please help me in finding the function module for the above request.
Thanks in advance!!!!!!!
Thanks,
Karthik

Hi Karthik,
For connection test you can use RFC_PING as said by Thomas, for checking authorization using Uname/PWD etc use RFC_LOGIN.
My Bad - You cannot use RFC_LOGIN, you can try with RFC_LOGIN_INFO and check the parameter "RFC_LOGIN_COMPLETE".

Chen

Java Stack mandatory for a SAP BI system integrated with EP?

Hi Guru's,
Currently we are using SAP NetWeaver 2004 s version 7.0 system for our BI.
This is integrated with the EP. But our BI system does not contain the Java Stack installed.
When we work on WAD templates and execute the template, it is automatically directed to EP portal where we can see our reports.
Here my question is do we need Java Stack for this system to use ADOBE DOCUMENT services or can it work with EP only for the web functionalities.
Any info on this is of great help.
Best Regards
Kumar

HI Reddy,
We came to know from our basis team that we do not have the Java Stack installed in our BI 7.x system yet.
As it is integrated with EP which has Java, our web reports are working.
1) But my question is still do we ned to install the Java Stack in our BI system as i do not find any Export to PDF option in EP for the reports (eventhough AS Java supports this).
2) Or can we use the existing configuration without Java STack integrated to EP for the new tools like Report Designer and Integrated Planning?
Regards
Kumar

Can SAP BI (BW) stand alone as a data warehouse for Non-SAP Source Systems.

I recognize that the answer to this question depends on the version of SAP BW we are discussing. My question is one being posed to determine how SAP BW fits in with the BI world and the other tools available.
- Can a company implement SAP BI without also having the SAP ERS applications?
- If so, will SAP BI effectively support 3rd party source systems and what is needed to make it effective (NetWeaver XI, NetWeaver 2004s)?
Thanks for your expertise.
Denny

hi dear,
clearly the most valuable input given by BW is a native integration with all SAP world...
well, you can manage a BW without having a SAP ERP as source system:
