Call RFC on non ABAP-Host

Hi experts,
we try to integrate a machine into SAP.
Therefore we want to use RFC-Communication.
This means, the machine will call RFC-FMs on SAP.
I know that this works and I only need to create a "normal" RFC-FM.
But how can I call a RFC-FM on the machine out of SAP?
Do I need to make a an RFC-FM like in ABAP but the destination is the machine (which is defined in SM59)?
Kind regards

Hi ,
Please learn this link Connections to Non-SAP Systems (SAP Library - ALE Programming Guide)
http://help.sap.com/saphelp_nw04/helpdata/en/52/16aafa543311d1891c0000e8322f96/content.htm
You can take a look into idocs. For idocs processing you require RFC Library of the RFC Software Development Kit (RFC-SDK) on the non sap system side for processing RFC's.

Interface SAP/ABAP-Host - Non SAP/ABAP Host

Hi experts,
I need to define an interface technoloty between an ABAP-host and a Non-ABAP host.
I know, that non-abap hosts are able to call RFC-Function Modules of the ABAP-host and that I can use this method to exchange data between the systems. This means, the non-abap host starts the action.
But I don't know, how I can do it on the other way, so that the ABAP-host starts the action.
So how can I call a function/program on the non-abap host out of SAP?
Do I need to define this as an external program call in SM59?
And if so, how does the syntax needs to be look-like, which I need to implement in ABAP.
Is it an normal RFC-FM which has the destination of the SM59?
Kind regards and thank you for every tip.

Hi Christian,
SUP i.e Sybase is the interface which is used to connect non SAP to SAP system via RFC-FM. It does not require to do RFC settings through SM59.

NW RFC SDK: Non-SAP to ABAP with username (trust relationship)

Hello,
I have a quite challenging non-SAP-to-ABAP RFC scenario with a trust relationship.
Hereu2019s the scenario:
An Oracle database server acts as an RFC client and calls RFC function modules in an ABAP server. (I assume the Oracle programmers are going to use NW RFC SDK 7.1 or JCo 3.0 on the Oracle server and call that from their PL/SQL based database application.)
The challenge is that I donu2019t want to use a single u201Ctechnical useru201D on the ABAP side because that would mean that all the users on the Oracle side would be mapped to one single ABAP user. Also, I donu2019t want to have to store individual ABAP passwords on the Oracle side.
Instead, I want the ABAP server to trust the RFC client the same way it might
a) trust a NetWeaver AS Java server after installing the Java serveru2019s certificate in transaction STRUSTSSO2 or
b) the way it might trust another ABAP server after configuring a trust relationship (transaction SMT1?)
The ABAP server should accept incoming RFC connections from the Oracle RFC client with just the user name and no password given and run the resulting processes in the ABAP system under the user id given in the RFC call.
I imagine the ideal solution somehow along the following lines (simplified scenario for a PC-based prototype):
- I download run a program that creates a certificate file (public key?) which I import into the ABAP system.
- The same program creates a matching file (private key?) for the RFC client.
- For reasons of simplicity, let us imagine the RFC client as a stand-alone Java SE application running on a PC.
- The Java SE application uses the JCo library to connect to the ABAP system.
- When opening the connection, it passes a username, but no password. Instead, it passes a Base64-encoded string that was generated by our key/certificate generator program.
- On the ABAP side, the function modules are run under the username used by the Java SE application when establishing the RFC connection.
Is that possible at all? How would you solve this?
Thank you very much in advance and best regards,
Thorsten

Hello,
Thanks a lot for your extremely high-quality replies. Iu2019ve been trying to work with them.
Frankly, just when (after Gregoru2019s and Timu2019s posts) I was hoping that working my way deeply enough into SNC, I would be able to solve my problem, Wolfgang comes along and tells me what Iu2019m aiming at wonu2019t work. Now Iu2019m confused.
The way I understand Wolfgang, the special trust an AS ABAP can put into another AS ABAP or an AS Java (u201Cremote RFC client, give me one certificate and I will accept every username if they come from youu201D) can not be put into a custom-made remote server software (such as the Oracle server application) acting as the RFC client, because when acting as RFC clients, the remote AS Java or AS ABAP use proprietary elements of the RFC protocol which are not available to me when I program my RFC client in the Oracle application.
@Wolfgang, is that correct?
Solution 1: Individual X.509 Certificates
Instead, I can establish X.509-based trust relationships at the level of individual usernames: create a certificate for each Oracle user, import them into the AS ABAP, map them to an ABAP user, and store the certificate on the Oracle side (Iu2019m still note sure about the different certificates and keys used publicly and privately here).
Solution 2: AS ABAP as User Management Engine for the Oracle Application
I can also see an alternative that would spare me the trouble of generating, importing, mapping and storing the certificates: delegate the user management to the AS ABAP and delete the (custom-built) logon and password-checking mechanism in the PL/SQL application:
Users are created centrally in CUA and distributed along with their passwords into (among others) the AS ABAP.
When a user logs on to the PL/SQL application, the username and password are sent for validation to an ABAP BAPI.
If authentication is successful, the AS ABAP returns a SAPLogon ticket which can be stored in the session context of the PL/SQL application and used in subsequent RFC calls. The password (a hash?) would only be transferred once during logon.
What do you think? Would both solutions work or am I still getting something wrong? Can you see a better alternative that would reduce
for solution 1 the administrative overhead for synchronization
for solution 2 the run-time dependency Oracle-ABAP and the change impact on the Oracle applicationu2019s user management concept?
Thanks a lot,
Thorsten

How to call the rfc in webdynpro abap..?

Dear Experts,
I need to add two numbers using RFC in webdynpro abap.
First we have to give the input then click the submit button.. The result will be shown in next screen with addition of two numbers... Please help me in this...
Thanks.

Calling an RFC Function module in Web Dynpro ABAP is nothing different from Classical ABAP
use Pattern button to call function module and use DESTINATION syntax to specify the RFC destination
http://www.octavia.de/fileadmin/octavia_files/content_bilder/Hauptnavigation/SAP_NetWeaver/WebDynpro/Web_Dynpro_Part_II.pdf?PHPSESSID=c528a60bf8857431c0fa6f6595639da7
In Above document, page no 7, there is a wizard for Service call, in that 4th step is select service where
you can specify the function module name and the rfc destination name

How to Call the RFC in Webdynpro abap application

Dear Experts,
Good Evening to all...
I have to add two numbers using RFC in webdynpro abap application. If we give the numbers in the input screen then the RFC should add it and give it in the output screen. This is the application for that I have created the RFC.
But the problem is i don't know how to call the RFC in that Webdynpro abap application and how to link the input view and output view with that RFC...? I am new to Webdynpro abap. Please kindly help me on this... I am struggled here... I need your help in this....
Thank You.

Hi Jaga,
You asked the same question again.
Without closing the [previous one|Re: Where SAP store the uploaded files?].
I think Abhi has answered your question.
If not please elaborate on the problem.
The solution btw is to create a Service Call.

How can I call RFC FM from webdynpro application for ABAP? Please help!

Hi Experts,
I have a requirement where I have to make a call to RFC enabled function module passing some data from webdynpro for ABAP application. How can I achieve this? Any tutorial or links or docs will be very helpfull.
I have seen some tutorial on Adaptive RFC but it talks about webdynpro for Java.
Can I use "Call function XYZ destination A10" statement in webdynpro for ABAP application?
Thanks

am doing same thing for my current SRM implementation.I am taking data to SRM server from another R/3 server .
This is solution I have used
1) First of all I have made ABAP connection in SM59 .
Go to SM59 .In ABAP Connection creat ABAP connection with system with which u want communicate .
Eg I am connection with Systems PB1.
So i developed Connection call PB1CLNT800.
2) In my requirement I have taken data in my context from another r/3,
I have give called RFC in my supply function of node.
Call to RFC is as usual.
In my case,
CALL FUNCTION 'RFC_MATNR'
DESTINATION 'PB1CLNT800'
TABLES
IT_MATNR = IT_MATNR.
Onwards I have read my itab IT_MATNR and populated data to context.
Hope solution will serve your purpose.
Give point if it works .If any problem i have other ways.
Cheers

Hi,
I changed the name of the server and I have the same error. I changed the server name on: RfcServerManager.GetServer("SERVER_NAME", handlers); do I need to change in some other place?
Did you made any more changes on SAP or c#?
Anyone have any suggestions on how to solve this problem? I'm trying everything and I still could not solve...
Any help will be appreciated.

The webdynpro/ABAP (WDA) calling RFC enabled FM of other ECC systems

The webdynpro/ABAP (WDA) has problem calling RFC enabled FM of other ECC systems.
WDA expects all the ABAPs, RFC FMs of remote system(DEV, QA..) to reside inside its own instance.
It is hard to transport and maintain these ABAPs FMs into a portal ABAP WDA instance.
Proxy generation at WDA client:
=======================
1. If we can make an XI enable an ABAP or RFC enabled FM of the remote ECC,
I think the XI proxy classes can be generated at the client WDA system.
Other options?
How do I do it? Can you give some tips.
2. How do I manually code the RFC Call to BAPI/FM from Webdynpro controller or other interface?
I am stuck with the above as the webservice option is not available at our ECC server. It does not have a java engine installed for webservice to be available.
Can you help on the above 2 options?

Calling Azure Key Vault from a non Azure hosted application

Hi,
I need to know whether I can call the Azure's Key Vault from a non Azure hosted application which is either running on a private cloud or on premise. I believe it will as long as I authenticated with that MS Azure AD and then use the token to access the
Azure's Key Vault.
Regards,
Wahaj

Hi Wahaj,
Yes you can, there is no requisite that the consuming client should be azure hosted. It can be a console application too running on your local system, as long as it is able to authenticate against the azure ad. The sample that I have used
here is a console application that talks to the key vault service.
Let know if you need any additional information
Please mark posts as answers/helpful if it answers your query. This would be helpful for others facing the same kind of problem

Error while calling RFC

Hi all WebDynpro Gurus
I am using EP7.
I am developing an WD application for KM functionality in which I need to call RFC from backend. I followed the "Creating WD application accessing ABAP function" example.
But when I executed the application I got following exception.
Root Cause
The initial exception that caused the request to fail, was:
com.sap.lcr.api.cimclient.CIMClientException: java.net.MalformedURLException: URL must have a host part
Correction Hints
Accessing the System Landsape Directory (SLD) failed. Depending on the concrete reason (see root cause) check the following:
is the SLD Supplier in the J2EE engine configured correctly? See the SLD documentation for more details about the SLD and about how to configure it.
are all JCO destinations maintained correctly? Use the preinstalled Web Dynpro Content Admin application to check/edit the destination. Use the Ping and Test functions of the Content Admin to verify that each destination is properly configured.
I checked JcO connections in the webdynpro content admin. There the status is unknown and create tabs are disabled.
I checked the SLD connections in content admin , the entries are as below:
Host name : blank
Port: -1
User: blank
Url: http://.-1/sld
Where could i configure these SLD settings and what should be the new entries ?
I dont have permission to view WebDynpro console.
Please help me out.

Vinod,
Claim: "Hello, World" application with WD and RFC is the "Hello, World" application with most complex configuration.
Prove:
1. You need to run http://host:port/sld and import CIM context
2. You need to add technical WebAS ABAP systems to SLD (same URL)
3. You need to run Visual Administrator and setup SLD connection parameters (host, port, user, password)
4. You need to (re)deploy your WD application
5. You need to run web-based WebDynpro Content Administrator and configure JCO connections.
Fortunately, [1]-[4] is necessary only ones per server, [5] is necessary per every application.

Error while calling java program from ABAP

Hi Experts,
We are trying for RFC inbound scenario.
We followed the below blog
/people/gregor.wolf3/blog/2004/08/26/setup-and-test-sap-java-connector-outbound-connection
We are working with SAP JCO 3.0.2
We are getting the error : 'STFC_CONNECTION' could not be found in the server repository.
After I run the Java server program if I execute the RFC destination directly from SM 59 it is showing successful messages.
If I stop the java program then this RFC is failing. Based on this we concluded that RFC to Java connection is working fine.
But as mentioned in blog if we call the RFC Destination from ABAP program it is giving the below error,
'STFC_CONNECTION' could not be found in the server repository.
If we test the RFC destination using RFC_TRUSTED_CHECK standard FM we are getting the below error.
'RFCPING' could not be found in the server repository.
We create the RFC destination of Type : TCP/IP as exactly mention in the blog.
Please help us in resolving this issue.
Thanks
Prince

Pabi,
Using the RFC connection,we can establish a link between Java and SAP.
Afterwards,hope we can call Java program from ABAP.
Below is the sample piece of code to establish RFC connection(link) between Java and SAP.

      RESPTEXT LIKE SY-LISEL,
      ECHOTEXT LIKE SY-LISEL.
DATA: RFCDEST like rfcdes-rfcdest VALUE 'NONE'.
DATA: RFC_MESS(128).
REQUTEXT = 'HELLO WORLD'.
RFCDEST = 'JCOSERVER01'. "corresponds to the destination name defined in the SM59
CALL FUNCTION 'STFC_CONNECTION'
   DESTINATION RFCDEST

     RESPTEXT = RESPTEXT
     ECHOTEXT = ECHOTEXT

Yes, SAPHTTPA (runs on application server) and/or SAPHTTP (runs on front-end pc), one of which, is required for HTTP communication. So far, nothing too elaborate as far as SOAP goes, but the logic is simplistic. Here's some sample code:
DEST = 'SAPHTTPA'.
TRANSLATE HOST TO LOWER CASE.
MYURL = 'wssrvTest/Service.asmx/GetByOrderItem'.
CONCATENATE HOST MYURL INTO MYURL.
REQUEST_HEADERS-DATA =
 'Content-type: application/x-www-form-urlencoded'.
APPEND REQUEST_HEADERS.
CLEAR REQUEST_HEADERS.
*........Convert Order Number to External Format........................
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
 EXPORTING
 INPUT = ORDER
 IMPORTING
 OUTPUT = ORDER.
*........Convert Item Number to External Format.........................
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
 EXPORTING
 INPUT = ITEM
 IMPORTING
 OUTPUT = ITEM.
*........Convert Material Number to External Format.....................
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
 EXPORTING
 INPUT = MATERIAL
 IMPORTING
 OUTPUT = MATERIAL.
CONCATENATE 'sOrder=' ORDER
 INTO REQUEST_BODY-DATA.
APPEND REQUEST_BODY.
CLEAR REQUEST_BODY.
CONCATENATE '&sItem=' ITEM
 INTO REQUEST_BODY-DATA.
APPEND REQUEST_BODY.
CLEAR REQUEST_BODY.
CONCATENATE '&sMaterial=' MATERIAL
 INTO REQUEST_BODY-DATA.
APPEND REQUEST_BODY.
CLEAR REQUEST_BODY.
CALL FUNCTION 'HTTP_POST'
 EXPORTING
 ABSOLUTE_URI = MYURL
 RFC_DESTINATION = DEST
 BLANKSTOCRLF = 'X'
 TABLES
 RESPONSE_ENTITY_BODY = RESPONSE_BODY
 REQUEST_ENTITY_BODY = REQUEST_BODY
 RESPONSE_HEADERS = RESPONSE_HEADERS
 REQUEST_HEADERS = REQUEST_HEADERS
 EXCEPTIONS
 CONNECT_FAILED = 1
 TIMEOUT = 2
 INTERNAL_ERROR = 3
 TCPIP_ERROR = 4
 DATA_ERROR = 5
 SYSTEM_FAILURE = 6
 COMMUNICATION_FAILURE = 7
 OTHERS = 8.
CHECK SY-SUBRC = 0. "more appropriate msg goes here
LOOP AT RESPONSE_BODY.
 IF RESPONSE_BODY+0(7) <> '<string' AND
 RESPONSE_BODY+0(8) <> '</string' AND
 RESPONSE_BODY+0(5) <> '<?xml'.
 SPLIT RESPONSE_BODY-DATA AT '=' INTO FIELD_NAME FIELD_VALUE.
 TRANSLATE FIELD_NAME TO UPPER CASE.
 CASE FIELD_NAME.
 WHEN 'HEIGHT'.
 HEIGHT = FIELD_VALUE.
 WHEN 'WIDTH'.
 WIDTH = FIELD_VALUE.
 WHEN 'LENGTH'.
 LENGTH = FIELD_VALUE.

 WEIGHT = FIELD_VALUE.
 WHEN 'QTY'.
 QTY = FIELD_VALUE.
 ENDCASE.
