Create RFC in R/3

Hey guys
i m tryin to do a SOAP to RFC scenario and taking help of the following weblog
/people/shabarish.vijayakumar/blog/2006/03/23/rfc--xi--webservice--a-complete-walkthrough-part-1
its an excellent blog but as i m new to the SAP world i don't know how to create RFC.
can anyone provide me with some links as to how to create the RFC for the above scenario.
thanx
ahmad

Hi Ahmad,
not sure if you mean RFC destination or function module remote enabled (as in the scenario RFC to WS).
If you need to create a function module (function to be called on the backend system) then best would be to go through SAP documentation <a href="http://help.sap.com/saphelp_nw04/helpdata/en/9f/db988735c111d1829f0000e829fbfe/frameset.htm">Function Modules</a>, you need a developer key on R3 (in simple words you need development rights) and ABAP knowledge.
If you need to create an RFC destination then follow this: <a href="http://help.sap.com/saphelp_nw04/helpdata/en/22/042638488911d189490000e829fbbd/frameset.htm">Displaying, Maintaining, and Testing Destinations</a>
Hope it helps,
Kind Regards,
Sergio

Authorization Required in satellite system to create RFC

Dears,
In Solman 7.0 tcode SMSY i am adding satellite system(ECC6).As while creating RFCs
SM_<SID>CLNT<client>_READ
SM_<SID>CLNT<client>_TRUSTED
SM_<SID>CLNT<client>_TMW
in SMSY it askes for three times satellite system user name and password.
Now Issue is that with what authorization i should enter in satellite system so that RFCs can be created successfully as SAP_ALL can be assigned due to policy.I gave almost all basis tcodes to my user in satellite system but still RFC are generating error.
Please suggest.
Deepak

Hi,
You need to have these authorization objects. Along with your BASIS authorization add the following objects.
S_RFC
S_RFCACL
This should solve your problem.
Feel free to revert back.

Hi Azeem,
Just before creating the rfc connection do this step.
Set-Up Solution Manager Connection to Solution Manager Diagn
Use
Check the connection to function Solution Manager Diagnostics.
Default Settings
The function Solution Manager Diagnostics is installed on the Java instance of the Solution Manager system by default.
Activities
If the default values are correct, save the settings.
To run the Solution Manager Diagnostics in another system, enter the required data and save.
Also check that your java is active.

Best practice for creating RFC destination entries for 3rd parties(Biztalk)

Hi,
We are on SAP ECC 6 and we have been creating multiple RFC destination entries for the external 3rd party applications such as Biz-talk and others using TCP/IP connection type and sharing the programid.
The RFC connections with IDOC as data flow have been made using Synchronous mode for time critical ones(few) and majority through asynchronous mode for others. The RFC destination entries have been created for many interfaces which have unique RFC destinations with its corresponding ports defined in SAP.
We have both inbound and outbound connectivity.with the large number of RFC destinations being added we wanted to review the same. We wanted to check with others who had encountered similar situation and were keen to learn their experiences.
We also wanted to know if there are any best practices to optimise on number of RFC destinations.
Here were a few suggestions we had in mind to tackle the same.
1. Create unique RFC destinations for every port defined in SAP for external applications as Biztalk for as many connections. ( This would mean one for inbound, one for outbound)
2. Create one single RFC destination entry for the external host/application and the external application receiving the idoc control record to interpret what action to perform at its end.
3. Create RFC destinations based on the modules it links with such as materials management, sales and distribution, warehouse management. This would ensure we can limit the number of RFC to be created and make it simple to understand the flow of data.
I have done checks on SAP best practices website, sap oss notes and help pages but could not get specific information I was after.
I do understand we can have as unlimited number of RFC destinations and maximum connections using appropriate profile parameters for gateway, RFC, client connections, additional app servers.
I would appreciate if you can suggest the best architecture or practice to achieve RFC destinations in an optimized manner.
Thanks in advance
Sam

Not easy to give a perfect answer
1. Create unique RFC destinations for every port defined in SAP for external applications as Biztalk for as many connections. ( This would mean one for inbound, one for outbound)
-> be careful if you have multi cllients ( for example in acceptance) RFC's are client independ but ports are not! you could run in to trouble
2. Create one single RFC destination entry for the external host/application and the external application receiving the idoc control record to interpret what action to perform at its end.
-> could be the best solution... its easier to create partner profiles and the control record will contain the correct partner.
3. Create RFC destinations based on the modules it links with such as materials management, sales and distribution, warehouse management. This would ensure we can limit the number of RFC to be created and make it simple to understand the flow of data.
-> consider this option 2.
We send to you messagebroker with 1 RFC destination , sending multiple idoctypes, different partners , different ports.

How to create RFC Destination without using SM59?

Hello all:
We are troubleshooting an issue. An user created a RFC destination. He claims that he did not use SM59. We checked his access and do not have SM59 in his roles.
He configured VIRSA FireFighter. During the configuration, he created RFC destination. Document says use SM59 or contact BASIS Admin. He claims that he used a config table and he don't remember the config table name. RFC screen shows his ID as creator of the RFC.
We are trying to understand how an RFC can be created (outside of SM59) and plug the security hole in the environment.
Any insights would be appreciated.
--Anand

The FireFighter solution changes the RFC destination of the service user "on the fly" without S_TCODE checks for 'SM59'. But if I can remember correctly when looking into this, it does not create the RFC destination (in SM59) "on the fly".
> He claims that he used a config table and he don't remember the config table name.
Theoretically this is possible - a config table to define the name of the destination, and then create it if it does not exist yet (when used).
Otherwise, see SAP note 587410 and restrict (remove) his authority for the test environment (concentrate on S_DEVELOP, not S_TCODE - as you have also experienced).

Julius

How to create RFC(TCP/IP Connections) For BW Maintain BI accelerator Index?

Hi Howard,
is this your first usage of BWA? Normally this config is done by the initial installation normally from your HW vendor.
Please use the python standalone tool trexadmin to setup this RFC connection:
1. Log on with the user <sapsid>adm.
2. Enter the following:
cd <TREX_DIR>
./TREXAdmin.sh
Go to the tab 'Connectivity' and create a new RFC connection.

How we create RFC in SAP R/3

Hi all.
I want to create a iview and when i click on preview or Deploy, it shoud display screen of Transcation SE11.
I think we can do this by creating RFC of transcation(SE11). So Please tell me-
How we create RFC in SAP R/3 for transcation SE11.
I will rewards u points.
Thanks in advance

Naresh Kumar

Hi Naresh,
there is better way, you can display an transaction in the portal with an iView. Then use this URL of the transaction, then you can insert a html view with the URL of the transaction.
You can add tabs with different transactions for example.

Marcel

Use the authorization object while creating RFC

Hi All,
I'm able to create a RFC, can login from one sap system to another sap system and use the following FM. Here my concern is how to make the RFC more secure, i mean any user can access the target system with my login. Meanwhile came across a authorization object text box in the LOGON and SECURE tab while creating RFC.
so please put on light on how to authenticate the specific user to logon using the RFC.
Thanks in Advance.
Regards
Lalitkumar.

Hi Lalit,
Usually for RFC connection will be done with the, user type   system user type (means,they should not be able to login to system thru GUI)
2. Even if the user know the login id / password, he should have auth to create RFC like (SM59 and related auth objects)
and even for remote connection also we have different auth to restrict
3. These type of authorization will be given to basis guys only.
4. Logon/Security
             Lang-En
             Client-` client no
             user- user
             Password - bw password.
Here you will be specfying the user id ( system type) / password for connecting from one system to another.
and in next tab you can do Test connection.

Error creating RFC function /BODS/ABAP_RUN : RFC_ABAP_EXCEPTION-(Exception_Key: FU_NOT_FOUND, SY-MSGTY: E, SY-MSGID: FL,

Hi Expert,
I try to execute job on development system but he showed error "Error creating RFC function </BODS/ABAP_RUN>: <RFC_ABAP_EXCEPTION-(Exception_Key: FU_NOT_FOUND, SY-MSGTY: E, SY-MSGID: FL, SY-MSGNO: 046, SY-MSGV1: /BODS/ABAP_RUN)>. Notify Customer Support.
In ECC I use ABAP execute option as Execute Preloaded. How to solve this problem? Thanks for your advise.

Dear,
have you checked in EXX wether the function group /BODS/BODS is available?
Some notes here:
You will have to have to import the new ABAP Program group "BODS/BOS" which you can find in the local install folder...
Here are some details:
Installing Functions on the SAP Server
SAP BusinessObjects Data Services provides functions that support the use of the ABAP, BAPI, and
IDoc interfaces on SAP servers. You will need some or all of these functions in the normal operation
of the software in an SAP environment. These functions perform such operations as dynamically loading
and executing ABAP programs from Data Services, efficiently running preloaded ABAP programs,
allowing for seamless metadata browsing and importing from SAP servers, and reporting the status of
running jobs. Some of these functions read data from SAP NetWeaver BW sources.
You must upload the provided functions to your SAP server in a production environment. It is
recommended that you always upload the functions to your SAP server whether you are in a
development, test, or production environment. The functions provide seamless integration between
Data Services and SAP servers.
The default installation places two function module files for SAP servers in the ...\Data
Services\Admin\R3_Functions\transport directory. You then upload these files to SAP servers
using the SAP Correction and Transport System (CTS) or manually. Using CTS allows for version
control as the functions evolve across releases.
The installation provides two versions of transport files (depending on the server version you are using)
to install the functions on the SAP server. To obtain the names of the latest transport files for installing
or upgrading these SAP server functions, see the readme.txt file
And I've found those files and text files in the local install folder....in:
Program Files\SAP BusinessObjects\Data Services\admin\R3_Functions
(that's where I've installed it).
There you'll find some descriptive txt as how to proceed.
After installing, it might happen that the executing user is missing some authorizations.
Here my authorizations team helped me by tracing the user and then adding the necessary rights.
Sure hope this will help you.
Notes to check:
see SAP Note 1919255
Note 1916294

RFC - XI - WEBSERVICES scenario - Where to create RFC Destination

Hi Experts
For my RFC - XI - WEBSERVICES scenario, I have to create one TCP/IP RFC destination on R/3 system with the following details
RFC Destination Name    : XXXX
Connection Type            : T (TCP/IP)
Activation Type              : u201CRegistered Server Programu201D
Program ID                      : YYYY
Gateway Host                : R/3 Details ..??
Gateway Service           : R/3 Details ..??
My Function Module (Remote-Enabled) - u201CZZZZu201D is defined in R/3 System.
This Function Module should be communicated with the target system i.e. NW XI system
As per the Note from SAP Help: To be able to communicate using RFC, you need to define the target systems as RFC destinations in the sending system(R/3)
Target system u2013 XI Server
Sending system u2013 R/3 System
Are my details provided are good enough as per my explanation? Please guide me in this regard.
QUESTION : Where exactly do I need to create the RFC Destination(SM59)? on R/3 side or on XI side?

Refer the following link-
http://www.sdn.sap.com/irj/scn/weblogs;jsessionid=(J2EE3414700)ID1636235450DB01012070359836134304End?blog=/pub/wlg/1438
what are the inputs should be given to Gateway Host and Gateway Service while creating RFC Destination??
Open transaction SMGW on the R/3 system and choose
Goto -> Parameters -> Display. Beneath Attributes there will be the
entries 'gateway hostname' and 'gateway service'.#

Hello,
You need to setup an ABAP communication client and system, that's done through the TMS settings:
For source system:
- CTC                                              1
- CTS_SYSTEM_TYPE                          JAVA (others for a MDM system)
- NON_ABAP_SYSTEM                          1
- COMMUNICATION_SYSTEM:              (SAPSID of the ABAP communication system (e.g. the domain controller))
- NON_ABAP_WBO_CLIENT                    (Client of the ABAP stack on which the Transport Organizer Web UI (CTS_BROWSER) is activated and will run.)
- WBO_GET_REQ_STRATEGY                 TAGGED
- WBO_REL_REQ_STRATEGY                 MANUAL
For quality and production Java system (target systems):
- CTC                                              1
- CTS_SYSTEM_TYPE                          JAVA (others for a MDM system)
- NON_ABAP_SYSTEM                         1
- COMMUNICATION_SYSTEM:                 (SAPSID of the ABAP communication system (e.g. the domain controller))
- DEPLOY_WEB_SERVICE                       CTSDEPLOY
- DEPLOY_DATA_SHARE:
When this is done correctly, you will see the fields ABAP communication system and client populated in SMSY.
When ChaRM needs to operate on the non ABAP systems, it will take the RFCs for the communication system and client.
Best regards,
Miguel Ariñ

Steps to create RFC iview

Hi ,
I am new to create RFC iview,
So please let me know steps to create RFC iview and one Example.
regards
mmukesh

In its simplest steps:
1 Create an SAP system in the system landscape - don't use Conenction String as the type.
2 Give it an alias.
3 Set permissions so your administrators and endusers can access the system.
4 Use the RFC iView creation wizard and select the system alias and your RFC.
5 Make sure you do step 4 as a user who has RFC access to the SAP system.
6 Test it!
Please note that changing the RFC iView after creation is a little messy. You might be better off using the Visual Composer - it is much neater at displaying RFC table data than the RFC iView.
Cheers

Creating RFC dest'n for Registered Server Program

Hi,
I want to create a create a RFC destination for RFC Sender adapter. I am consulting this weblog:
/people/michal.krawczyk2/blog/2005/03/29/configuring-the-sender-rfc-adapter--step-by-step
However, i dont know what will be the Program ID and GatewayHost.... Please let me know how they are configured?
Regards,
Arpil

Program id can be any name thats unique and given while u select registered server program in sm 59 (while u create rfc destination of type TCP/IP)also its case sensitive, and should be same in both the RFC destination and your RFC adapter.
and gateway host has to be ur own application system not of XI ,(as specified in Michals blog) .
TCODE : SMGW -> Goto-> Parameters -> Display
