Connection to SAP R/3 or to particular module..n how??

i m new to Enterprise Portal and m bit confused.. i knw that EP is used to connect to SAP system thru Single Sign ON....
for my project we will be using ESS and MSS buisness package.
Thus we need to connect our Portal to nly SAP R/3 sytem...or v connect to particular module...considering my project i need to connect to SAP HR module.. so how do i configure my portal to only SAP HR module..or creating only SAP R/3 system..i.e the way we normally connect to SAP R/3 from Portal content studio will do..??
...if any one could explain it conceptually will surely b awarded POINTS..

Hi Jigar,
as you know about SSO it is nice, SSO is used to connect to backend (System) you can say R/3. Where as system contains many modules.
Create one system in portal which will connect to your desired backend using SSO. Once it succeeds.
Then create an SAP transaction iview from iview template which will point to this created sytem.
You must be having some t-code to directly access your module in the R/3.
You have to enter this t-code in the Transaction code property of the iview. After creating this iview and proper SSO settings, when you pre-view this iView it will directly open the first screen of your module/application in the backend system.
let me know if you face any issues in this.

Connect to SAP gateway failed - internal error

Hi, I've developed a simple .NET application that connects to a SAP system and makes a function call using a SAP Connector Proxy object. Everything works fine in my workstation, but deployment doesn't. I'm also deploying the following libraries: SAP.Connector.dll, SAP.Connector.Rfc.dll and librfc32.dll.
The fact is that deployment works fine in some servers, but not in others. I've checked that .NET Framework is installed (both versions, 1.1 and 2.0). I've checked the "WINDOWS\system32\drivers\etc\services" file. What else should I check? Any idea? Every suggestion would be appreciated.
The error message is the following:
Connect to SAP gateway failed Connect_PM GWHOST=xxx.xxx.xxx.xxx, GWSERV=sapgw00, ASHOST=xxx.xxx.xxx.xxx, SYSNR=00 LOCATION CPIC (TCP/IP) on local host ERROR internal error TIME Mon Nov 13 16:23:08 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -1 COUNTER 1
And the connection string:
CLIENT=100 USER=****** PASSWD=****** LANG=EN ASHOST=xxx.xxx.xxx.xxx SYSNR=0
Thanks in advance

Hi Daniel,
Can you connect to the particular system by using SAPGUI ?
if yes, then your librfc32 file is working fine.
NCo internally consumes it's functions.
Other points to check are
1> service name as appears from within the r/3 system [transaction : smgw]
2> NCo 2.0 uses .net 1.1 & nCo 2.5 uses .net 2.0, do you have both versions running parallely ?
3> gateway errors are infrastructure issues, please verify your firewall settings for the relevant protocols : http / https & also sap ports 3300 onwards.
the services file you have checked will list the ports that need to be opened on the firewall [in the case of multi - domain applications]
4> check in your 'hosts' file [same directory as your 'services' file]
This file contains the mappings of IP addresses to host names. Each
entry should be kept on an individual line. The IP address should
be placed in the first column followed by the corresponding host name.
The IP address and the host name should be separated by at least one
space.
Additionally, comments (such as these) may be inserted on individual
lines or following the machine name denoted by a '#' symbol.
For example:
102.54.94.97 rhino.acme.com # source server
38.25.63.10 x.acme.com # x client host
with respect,
amit

HTTPs connection from SAP WebAS

Hello,
I have to establish a connection from SAP WebAS to an iSaSiLk server via HTTPS.
The iSaSiLk authentication is based on client certificates.
I've created a SSL client PSE, generated the Certificate Request, imported the certificate response and the chain of certificates associated with no errors. When testing the connection we're getting the following error message:

From the iSaSiLk everything seems to be OK, but on the SAP WebAS the error "none of the PSEs registered with hSsl can suffice the negotiated SSL cipher suite" is really unclear, since the cipher chosen by the iSaSiLk is one of the ciphers sent by SAP WebAS...
Can anyone give me any suggestion?

An iSaSiLk server "is a Java programming language implementation of the SSLv2 (client-side), SSLv3, TLS 1.0 and TLS 1.1 protocols. It supports all defined cipher suites (except for Fortezza), including all AES and PSK cipher suites. iSaSiLk implements all standard TLS extensions, comes with an easy to use API and operates on top of the IAIK-JCE Javau2122 Cryptography Extension. iSaSiLk is highly configurable and will work with any alternative JCE implementation supported by a proper provider for supplying the required cryptographic algorithms".
Once again thanks for your answer.

Remote Connection from SAP to MS-SQL server

Hello Experts,
We have been following 2 options so far and we have come across some issues
The first Option is to call a stored procedure (this is our preferred method) which does the data transfer for us
We have been able to test this scenario successfully from SQL Server side
However, while calling the stored proc via native SQL from ABAP we have come across an issue which is due to SQL 2005 changes (Schema implementation and difference in the security context)
While calling the stored procedure from the ABAP Code we have an error
The program short dumps with runtime error DBIF_DSQL2_SQL_ERROR, exception CX_SY_NATIVE_SQL_ERROR. The database error code is 15274, and the error text is
"Access to the remote server is denied because the current security context is not trusted."
This issue is new after the SQL Server 2005.
We are trying to resolve that.
Secondly we have been trying the DBCON option as well as per OSS Note 323151
We have a few things thatu2019s impacting our scenario:
The remote servers are in a different domain
The remote servers are located in DIZ
Remote server is a named instance
Remote server has been configured with a different port than standard (1565) u2013 All Connection strings will need port in there
The Database name starts with a numeric value
Due a combination of factors as mentioned above the standard approach does not work
Have any of you used this approach while connecting from SAP to MS-SQL server? Do you know of any successful methods to connect to SQL using ABAP (or not) from SAP.
Thanks in advance,

Yes,
DBConnect & UDConnect.
Works like a charm.
We write data into a MS-SQL database via DBConnect & an ABAP program (using open sql).

SAP DB Connection from SAP BI on HP UNIX to MS SQL External Database

Dear All,
Greetings!
I have a scenario to configure a SAP DB Connection from SAP BI System on HP UNIX 11i to the external legacy system MS SQL 2000 Enterprise for data upload. I am interested in connecting the SQL server as a Source System to the BI System.
I read through documents mentioning about installation of a Client driver in the SAP BI System, I also downloaded the JDBC client software and tried installing the same, but the steps as mentioned Setting the CLASSPATH or connecting to the server did not work.
Please help me in connecting the SQL Server as Source System, I would like to know in detail about the same - so kindly help me with the links to documents and guides about the same.
Thank you
Regards,
Vineeth Damodar

Short answer: this does not work.
Long answer: To connect directly to the database you need
- a database client for the source system
- a database interface library for the source system
Both of them are not available for HP-UX if the target database is SQL server --> doesn't work.
What you can do is: add a Windows application server to your BI system (heterogeneous installations work and are supported) and add there the database client and the database interface library.

Connection from SAP 4.0B System to IBM MQ Series

Hi
is it possible to connect SAP 4.0B System with IBM MQ Series 6.0,is the connection supported by SAP 4.0B?
If supported I am confused with what is the RFC Destination to be used
is it R/3 Connections or TCP/IP connections
Thanks in advance
Warm regards
Rajasekhar

Hi Anup
Thanku for your valuable input, here in the TCP/IP connections can you please suggest what are the
ACTIVATION TYPE to be used there are 4 radio buttons, is it the
Registered Server Program OR
Start On Application serverOR
Start on Explicit Host OR
Start on Front End Work Station
if it is the registered server program what are the values to be used for PROGRAM ID
is it required to make any changes in SAPRFC INI File
Thanks in advance
Warm regards

Connection from SAP ERP 6 to B1i2007

Hello,
the test-connection between B1i and SAP is working, but when trying to test the connection from SAP to B1i, SAP gives the error mesaage that "the program is not registered".
The B1i-System seems to be not registered in the SAP and it is only shown as "external client" (and not as registered server).
Another problem is that in B1i we have entered as programID-name "B1iRFC" but SAP shows "tomcat5" as TP-name.
I thought B1i would register automatically on the SAP with the name of the programm-id entered.
Do we have to change someting in the tomcat-server or where to find the problem?
Thank you,
Peter

Hello Eddy,
thank you for your answer, but in R/3 I define a RFC-connection with a registered server programm by using the programID out of the B1i-RFCP-configuration, right?
And when trying to make a test-connection, I got an error message that there is no registered program with this programID.
I thought that B1i have to be registered in SAP or in the SAP-Gateway with the name of this programID.
I think my problem is the registered server program in R/3. Where do I get this program and how to register in the R/3 gateway? Isn't the tomcat-server this program?
Best regards,
Peter

Connection from SAP to our systems involving 2 saprouters

connection from SAP to our systems involving 2 saprouters
we have 1 saprouter inside a dmz and another for connecting to our systems.
we are guessing that this is possible
SAP (sapserv2) -
SNC----> saprouter1 (DMZ, SNC connection) -
> saprouter2 (P * * 3200) ---> SAP1, SAP2...
But how could we do that?
How can we let SAP know that they need to connect to 2 saprouters instead of 1?
The "Mantain System Data" in sap service marketplace only lets us introduce 1 saprouter.
And how should be the saproutettab of the 2 saprouters?
saprouter1:
KT "p:CN=sapserv2, OU=SAProuter, O=SAP, C=DE" 000.00.00.00 *
P * saprouter2 3299
saprouter2:
P * * 3200
P * * 3600
is that possible?
Many thanks !!

Hi
As far as my experience goes with this you have to maintain both router information in oss1 tcode
Also mention second router on the second router tab on the SMP data
I hope it should work with that as it will automatically create router table

Is this possible: SNC connection from SAP GUI to SAP Router, and ...

Hi,
I have (stupid perhaps) question.
Is this scenario possible:
SNC connection from SAP GUI to SAP Router, and non-SNC connection from SAP Router to SAP System.
I know how to set up scenario like this:
SAP System --- (non-SNC conn) --- saprouter1 --- (SNC conn) --- saprouter2 --- (non-SNC conn) --- SAP GUI.
Best regards,
Marek Majchrowski

Wolfgang,
To be sure myself and Marek understand, can you confirm the different scenarios supported:
Scenario 1:
SAP GUI --- (non SNC conn) --- saprouter1 --- (SNC conn) --- saprouter2 --- (non-SNC conn) --- SAP System
With this scenario, it would be possible for a user to logon using SAP GUI onto the SAP System, but without SAP GUI SNC.
Scenario 2:
SAP GUI --- (SNC conn) --- saprouter1 --- (non SNC conn) --- saprouter2 --- (SNC conn) --- SAP System
With this scenario it would be possible to logon to the SAP System using SAP GUI, and using SNC authentication.
Also, with this scenario the SAP GUI software and SAP System software would consider this to be similar to:
SAP GUI -- (SNC conn) -- SAP System
Scenario 3:
This is the scenario mentioned by Marek in his initial question:
SAP GUI -- (SNC conn) -- saprouter1 -- (non SNC conn) -- SAP System
With this scenario it will not be possible to logon to SAP System using SNC, and only possible if the SAP GUI is configured to not use SNC. In other words the SNC connection between SAP GUI and saprouter1 is available, but cannot be used.
Thanks,
Tim

RSA1 DB Connection from SAP BW to external SQL Server databas.

Hello,
I am trying to connect our SAP BW system with SQL Server Source System through DB Connect in transaction RSA1.
Our BW system is running on Windows and MaxDB platform, therefore have I already added the latest dbmssslib.dll library to the kernel for SQL Server.
But the connection does not work anyhow, I recieve the error "Database error -1 at CON > [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does > exist or access denied." and I am quite sure that my input parameters are correct.
Therefore I wonder if someone has run into a similar problem and what the problem could be?
Best Regards,
Niklas Sandstedt

Hi,
I am sorry that my case was assigned to wrong forum.
That should now have been corrected, however my problem still remains unsolved in one of our systems.
I found note 178949, which fixed the problem in one system. But even though the system setup seems to be identical, the two systems appears different.
The following has been done for both systems:
1. Upgraded kernel to 701 version 111 and added dbmssslib.dll and dbmssslib.pdb files
2. Created Logical system in BD54.
3. Tried to create DB connection in transaction DBACOCKPIT.
In the third step, the setup fails and I receive the following error message when I test the connection:
Database error -1 at CON > [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not > exist or access denied.
Database error -1
All profile parameters AL11-directories also seems to be correct in both systems, so both should find the dbmssslib.dll file.
One issue that I see is in DBACOCKPIT, the checkbox for "SAP Systems with basis release" is unchangeble and marked. This however, I think was changed in the other system automatically when the connection was established successfully.
Has anyone run into the same problem?
Best Regards,
Niklas Sandstedt
