Call RFC From PL/ SQL

Hi Everybody, i have some question:
Its Possible from PL / SQL, call RFC Functions?...
Please can you give me some examples or tell me if is technicaly impossible to do that?..
Thanks a lot.
Greattings
Wilmer Figueroa

Hey,
It is not that easy,
SAP didn't published an package to link PL/SQL to RFC,
however, it is possible with some work:
the PL/SQL can execute command on operation system of the DB
for example 'dir' in windows or 'ls' in unix,
instead of running dir/ls you can execute a program that will execute an RFC in the SAP system.
the program can be developed by .Net connector, see:
NW RFC SDK - is there a guide somewhere?

Call RFC from DELPHI Windows Services Program

Hi all,
Are there any way to call RFC from DELPHI Windows Services Program?
Best regards.

Hi again Bhagat,
1. Yes, it's included on 7.4 ABAP Stack (SAP NetWeaver 7.4 SP8 - Optimized for SAP HANA, Cloud and Mobile - Service Release 2 available now!). In a recent customer, SAP licences GW by user but there are other license model like session licensing: https://store.sap.com/sap/cp/ui/resources/store/html/SolutionDetails.html?pid=0000009470&catID=&pcntry=US&sap-language=EN&_cp_id=id-1385059687642-0
2. You could install as an AddOn on your 7.3 system, there are many options depending on your desired infrastructure: SAP Gateway deployment options in a nutshell For example our customer have deployed Central Hub Gateway in a standalone stack ABAP to act as an standalone oData bridge between ABAP/nonAbap systems.
3. You could deploy SAPUI5 apps in 7.x, Java Web Servers or HTTP Web Servers. You must consider your SSO scenario:
- SSO Logon Tickets. You will need to configurate SSO Logon Tickets between SAP NW Portal & SAP NW Gateway & your backend (ECC, etc). In order to pass SAP session cookie you will need setup SAP Web Dispacther and access portal & gateway throught SAP WD with the same domain.
- SAML2 Tickets. This scenario lets you provide portal & gateway on different domains enabling SSO. You could configure SAP NW Portal as an Identity Provider and other systems must trust SAP Portal as IdP.

How to call RFC from Power Builder

Hi,
I am using Power Builder Tools and I want to know how can i call RFC from Power Builder
Thanks for ur reply

Hi,
Although I have not worked with Powerbuilder, I am sure if you have a certain level of proficiency with it, you will be able to code your logic that will call your wrappers written in VB/C/.NET etc. Check out the wonderful weblog by Thomas Jung on integrating ActiveX controls with ABAP Control Framework at https://www.sdn.sap.com/sdn/weblogs.sdn?blog=/pub/wlg/995.

i want to create my own log for each interface.
i saw this blog:
/people/michal.krawczyk2/blog/2006/09/20/xi-abap-mapping-logs--more-standard-better-visibility
my doubt is how to catch the error that i see in SXI_MONITOR y put it in a Sub-Objetc.
For example: in sxi_monitor i get the error for my interface NMUCustomer: "No receiver could not be found" or "Error Mapping Traformation".
I created an Object called ZNMUCUSTOMER and a Sub-Objetc called ZERROR.
what i must do to get the error I see in monitor and assign it to Sub-Object??

Calling RFC from custom connector

Hi,
I am developing a custom connector for UWL to get tasks from 3rd party system.
I need to call a RFC from backend SAP system to complete Input data for this 3rd party provider.
I assume that I have to make an RFC call from getItems() method of connector.
Any idea how to call a RFC from UWL custom connector code?
Please help.
Thanks & Regards,
Amey

Hello Karri,
Yes, I am aware of two ways of calling RFCs from Java code.
Normally, I use following approach to call RFCs from my other Portal Components (JSPDynpages): -
IPortalComponentRequest request = (IPortalComponentRequest) this.getRequest();
IPortalComponentContext myContext = request.getComponentContext();
IPortalComponentProfile myProfile = myContext.getProfile();
String sapSystem = myProfile.getProperty("SystemIdentifier");
ISystemLandscapeWrapper landscapeWrapper = (ISystemLandscapeWrapper) UMFactory.getSystemLandscapeWrappers().get(0);
ISystemLandscapeObject systemLandscapeObject = landscapeWrapper.getSystemByAlias(sapSystem);
IJCOClientService clientService = (IJCOClientService) PortalRuntime.
getRuntimeResources().getService(JCO_CLIENT);
request.getNode().putValue(LOCALE_NODE_KEY, Locale.ENGLISH);
IJCOClientPoolEntry poolEntry = clientService.getJCOClientPoolEntry(sapSystem,request);
JCO.Client client = poolEntry.getJCOClient();
client.connect();
IRepository repository = JCO.createRepository("repository", client);
IFunctionTemplate functionTemplate = repository.getFunctionTemplate(Z_BAPI_EMP_GBU_GET);
JCO.Function function = new JCO.Function(functionTemplate);
JCO.ParameterList importList = function.getImportParameterList();
importList.setValue("US", "OBJTYP");
importList.setValue(request.getUser().getUniqueName(), "USRID");
client.execute(function);
JCO.ParameterList outputList = function.getExportParameterList();
gbuCountryBean.setGbu(outputList.getString("GBU"));
gbuCountryBean.setCountry(outputList.getString("COUNTRYCODE"));
gbuCountryBean.setPersArea(outputList.getString("PERS_AREA"));
gbuCountryBean.setCompanyCode(outputList.getString("COMPANYCODE"));
When I tried implementing same in UWL custom connector, I am not able to get instance of 'request' object.
Any hints/ideas on this?
Hence as an temporary alternative, I wrote following to successfully execute RFC.
mConnection = JCO.createClient(sapclient, sapuser,
sappassword, "EN", saphost, sapsysnumber);
mConnection.connect();
mRepository = new JCO.Repository("GetLeaveRequestFlag", mConnection );
IFunctionTemplate ftemplate = mRepository.getFunctionTemplate(Z_BAPI_CHECK_LR_TO_APPROVE);
myFunction = new JCO.Function(ftemplate);
JCO.Field OBJECT_TYPE = myFunction.getImportParameterList().getField("OBJECT_TYPE");
OBJECT_TYPE.setValue("US");
JCO.Field USERID = myFunction.getImportParameterList().getField("USERID");
OBJECT_TYPE.setValue(p_userID);
mConnection.execute(myFunction);
JCO.Field leaveRequestFlag = myFunction.getExportParameterList().getField("FLAG_LEAVE_REQUEST_RECORD");
mConnection.disconnect();
But only catch here is that I need to create & maintain SAP logon credentials for a particular user manually.
It is not possible to single sign on connector user into SAP system (like its done above).
Any thoughts on this?
Thanks & Regards,
Amey

Calling RFCs from Web through XI

We have used SAP.NET connector in the past to call RFCs from ASP.NET pages from our public website. We have now decided to use XI as the enterprise integration engine going forward.I am interested to know whether anybody has used XI to call RFCs from ASP.NET webpages. I do know that the XI to SAP calls would be made through RFC adapter.Will the communication from ASP.NET page to XI be thourgh the HTTP adapter ? or is there any other smarter way. Can somebody point me to sample code for the calls through http adapter or a how to guide?
cheers

Hi
U have scenario like this ASP.NET->XI->RFC, that means u will send a value from the ASP.NET page to RFC thru XI and then this RFC will give result which will come to ASP.NET frontend.
For this go thru this blog it will help u to understand how to communicate from ASP.NET to XI

Advantages and Disadvantages of calling java from PL/SQL

Hi,
I have one doubt. What are all the advantages and disadvantages of the calling java from PL/SQL?
In actual scenario the java program will be in the Application server side. It will do the operation and it will store the result in Data base. But in this case (calling java from PL/SQL), we are loading the java program in the Data base and it is doing the operations.
I have seen many posts are coming regarding loading jar files into the database. Actually the jar will deploy in to Application server. Is there any difference instead of keeping in the Application server side?
Then I have read,
advantages:
-> java having lot API's. so PL/SQL can use that API's.
-> if we can not do anything in PL/SQL. we can do it using this mtd(calling java from PL/SQL).
My questions:
-> could you explain what are all the things we can not do but we can do using "calling java from PL/SQL" method?
-> is there any other advantages?
Disadvantages:
-> the performance is very slow in calling java from PL/SQL.
My questions:
-> Then why others are loading java files and jar files into database?
-> is there any other disadvantages?
Could you explain about this one? It will be more helpful to others also…

kk

Call report from pl-sql routine

I just got started on the report-tool, so, this might be a very basic question, but, would appreciate your
response.
I have a pl-sql routine registered as a concurrent program. How do I make call to report-builder from this routine.
Thxs,

Hello Chirag,
If you want to invoke and run a report from your PL/SQL code in the database, you can do so by installing and using the SRW package supplied with Reports. This package allows you to run parametrized report jobs on a specified Reports Server from your PL/SQL program and track the job status. Please take a look at the documentation for this package in the Publishing Reports manual on OTN at: http://download-west.oracle.com/docs/html/A92102_01/toc.htm.
On the other hand, if you just need to invoke the Reports Builder program from your PL/SQL routine, you would need to use the default builtin for calling external applications from PL/SQL.
Thanks,
The Oracle Reports Team.

Calling RFC from Adobe Interactive Form

Hello,
After creating and calling Adobe Interactive form from ABAP web dynpro, within the form designer is it possible to call RFC or Business Object method from the form script to get the data back from SAP for specific Click events?

Yes,
this is possible, but not through pure RFC, but using webservices and webservice enabled function modules within SAP.
Technically it is quite simple. Create a functionmodule, and create a webserve from that (all SE37 or SE80 but from WAS 6.40). Generate a WSDL (with the Java tool) and import that into the form that you are designing. From there you can bind the data from the dataset (as defined in the WSDL) to screenfields or treat the data any other way Javascript can.
BTW. I only managed this so far by using anonymous logins, so with a password and username bound to the webservice (in SICF).
Hope this helps, regards, Hans Gmelig Meyling

Call RFC from java (j2ee) / call to j2ee from R/3

hello
i´ve browsed the forum for some time to find how to:
1.) call ejb from r/3 system via rfc
2.) call rfc enabled function modules on r/3 from within an j2ee enviroment
but i didn´t quite get it, because i was a bit confused about all the mentionend techniques
what i found out about
1.) use ejb (session bean) and jndi; configure RFC-Engine Service (we use sap webas)
2.) use jco / jca
(or all rfc enables rfm´s are available as web service, but didn´t find anything about this)
so my question:
are these the preferred techniques to connect j2ee (webAS) <-> r/3; if not are there any others, maybe easier methods?
and last but not least: are there any good online tutorials for this topic?
thanks in advance
franz

Just as a short partial reply.
The generic Java --> RFC method is JCO (it will work on older versions as well), you can think of it as a JDBC driver where R/3 is the database, it behaves very similar in many ways.
EJB development on SAP WAS is really not any different from EJB development on any other J2EE server. The deploy tool is superb. very easy to use and the JNDI registry, etc. are standard stuff...
ABAP to EJB calls, haven't looked at this in over a year now, but back then we did a Proof Of Concept based on information at http://help.sap.com and it did work indeed. The only thing was back then that you needed to do a few tweaks to get it to work properly.
As mentioned above, look at the JCO examples and then you can ask more specific questions once you get stuck.
Good Luck!
Cheers,
Kalle
