RFC and Proxies

-> When we have Proxies why do we still to go for RFCs?
-> Could someone tell me the advantages and disadvantages of RFC over Proxies and Proxies over RFC?

Hi Nalina,
Advantages of Proxies over RFCs/BAPIu2019s :
u2022     Proxy communication is better than RFC/BAPI communication when performance is concerned. Stability and performance of ABAP proxies is high when compared to RFC adapter for BAPIs.
u2022     Proxies are used for both Synchronous and Asynchronous communication. EOIO quality of service can be obtained with Proxies and not with RFC/BAPI.
u2022     Proxy allows application acknowledgement handling very well which RFC/BAPI does not provide.
u2022     ABAP proxies support two different protocols i.e. XI and Web Services.
u2022     Proxies are used when you have large chunks of data coming in and that too if it is unstructured, so if it comes from a SAP system we go for a ABAP proxy.

Madhu

When to use RFC ,Idoc and proxies

When to use the RFC,IDoc and proxies.
What is the difference in using RFC,Idoc and proxies.
I want the therotical explanation of it.
I gone through some of the links.
i want the explanation which is there in simple words
and which is easily understand by the bigginers
those dont know more about adapters.

hi,
You use all these three things when the sender or receiver for XI is R/3 system.
You use proxy in sap 6.0 version or higher.
you use that when you dont want to use an adapter.
or very high volume of data has to be transfered.
you go for rfc which can be synchronous as well as asynchronous

About RFC and BAPI

Hello Masters,
What Makes the exact difference between RFC and BAPIs. Both can perfom same thing. BAPI uses the RFCs only. Then how can it justify?
Thank you

RFC:
RFC --- > Function module and general will be used to make call to function
sending the function (XI has RFC adapter)
BAPI:
BAPI ---> Other version of RFC (Objected oriented) mostly we will use for Sync
calls (Mostly in XI using proxies we will call BAPI's)

What are idocs, BAPI, RFC?
BAPI is nothing but the Business process programing interface which are standard and stable and these are store in the business object repository.
Standardized programming interface that enables external applications to access business processes and data in an SAP System
RFC is the remote function call which is used to call the function remotely which may be in same system or ather system
its also used communication between SAP systems , between SAP systems ,external systems.

This is a short description of BAPI and RFC
BAPI stands for Business Application Programming Interface. It is a library of functions that are released to the public as an interface into an existing SAP system from an external system.
RFC is the protocol used to call functions in an R/3 system by a caller external to R/3 or to call programs external to R/3 from an R/3 system.

RFC and PROXY

Hi all,
i have a standard bapi which is at receiver side,and i neeed to update the data .it is asynchronous.can i use a RFC adapter or should i use proxy here?
Regards,
keerthi

Hi,
There are advantages / disadvantages for RFC / Proxies / Idocs. Some of the differences are:
RFC and Proxy:
RFC/BAPI has its own overhead of function call.
Proxies communicate with the XI server by means of native SOAP calls over HTTP .RFC does not, so you have to convert from SOAP to RFC calls and vice versa. So XML conversion is required.
ABAP Proxies uses Webservice and Http Protocols.
If you use ABAP Proxy , you can reduce the overhead calling the function again and again.
Proxy and Idoc:
IDOC : After recieving the strucutred data It processes it using a Function Module associated with it.
Proxy : Proxy is a structure where there is no processing function module associated. You need to explicitly write the Business Logic/Call the subroutines here
Also go through this urls which may help you:

Choosing among IDoc, RFC and Proxy

Hi every one,
We have 2 SAP systems, one in the US and other in Kuwait.
The project is in the proof of concept phase. To communicate between the systems, I have a choice to choose among IDoc, RFC and Proxy.
Can someone direct me in this direction.
What are criteria that should be considered in choosing one of the methods of communication.
My other question is that,
there might not be internet facility at the remote location that is in Kuwait. I thought of going for asynch communication...I hope I am right in this.
Please correct me and direct me.
-Naveen.

I guess you should start with the scenarios that you have in hand.
During proof-of-concept stage, you analyze what kind of scenarios that you might encounter in the real-world or during the build stage and choose the technology (RFC/IDoc/Proxy) to prove the end-to-end capability of building an interface.
During the scenario evaluation stage, list out the "out-of-the-box" capabilities of both the SAP systems and come up with a decision tree of when to use RFC, IDoc or Proxies.
Also make sure that you include quality of service and error handling capabilities. In case of IDoc's the error handling capability is all standard and you don't need to build anything from scratch.
I guess these would be some criteria based on which you can evaluate which method to choose from.

What is the diffrence between BAPI and RFC and business object

Hi Experts,
Can anybody tel me what is the diffrence between RFC and BAPI , and also what is ther relation with business object?
Thanx in advance.
Nilesh Hiwale

Hi,
BAPI's are associated with Business Objects and also they are RFC enabled.
But RFC's are the FM's which can be called from external systems, those FM's can be used in many places based on the applications..

Monitoring of remote system's Transactional RFC and Queued RFC

Hello,
In our production system, in rz20- CCMS monitor templates- Communication-Transactional RFC and Queued RFc- outbound queues- Queues otherwise not monitored we can see blocked queues for each client.
System is connected to solution manager and we wish the central auto reaction is implemented in solution manager
However i am unable to find Transactional RFC and Queued RFC for the remote system, they exist only for solution manager itself
Tell me how can i do the central monitoring

Hello,
First you need to check with your Landscape in solman in order to monitor any kind of activities to do so pls follow these steps.
Go to SMSY in solman under Landscape components>Product systemsselect you satellite system example SAP ECC.
On the main screen you will find client for which you have generated RFC connection. Please check though connection are working fine, Go to edit mode and try to click on generate button there will be a pop-up, which gives a clear picture of RFC connection which already exists, and you can also re-generate this RFC connection by clean it up when you re-generate pls select under Actions after generation assign RFC dest for system monitoring.
But make sure there is no project impact on this RFC, like they are not using any logical components and already have some projects running on this RFC connection.
I would advise you to first you the option of assign and check RFC button which is next to generate icon.
Regards
JUDE

File to RFC, and through RFC response i am trying to trigger the Mail adapt

Hi All,
Right now i am doing File to RFC, its working fine but now the requirement is when xi connect to ftp and picks the file need to send one success mail after the file pickup and data sent to BW system again i need to send one mail and also error alerts to inbox.
Till now i am not using BPM, can we do this without BPM pls let me know
now i am trying to achieve this in File to RFC, and through RFC response i am trying to trigger the Mail adapter.
or else i need use only BPM pls share the steps which i need to be configure.
Am i correct or pls suggest me some idea to achive this and also pls share some smaple ones in BPM .
Thanks in advance
Venkat

With BPm, follow this:

Instead of receiving the response in file, use mail adapter

RFC and Logical System names

Hello......is it necessary to have RFC and Logical system name for the connected system to be identical?Is there any explanation behind this if thats true....

Hi Gaurav,
It is recommended, but not mandatory, right, Muthuraman?
The system uses some transactions to determine which RFC will be used for the communication between one system and another, for example, in transaction 'Define backend systems' in SPRO, you can define that the current SRM client has an ECC backend system named X and the RFC destination for this X system is Y (not necessarily the same name).

Exception handling in rfcs and bapis

exception handling in rfcs and bapis

Hi Jayakrishna,
In General , there are non execptions in BAPIs, because of the reason, that the exception raised in a SAP envoronment may not mean anything for a non SAP initiator. All the exception situations would only fill the return table(TYpe BAPIRET2 or something like that). If you read that table after the call to the bapi, you can understand what has gone wrong.

Can we open a URL link from an RFC and access the data in the link.?

Can we open a URL link from an RFC and access the data in the link.
I have the following scenario.
I have a URL link and it opens a KM folder in the Portal server and I need to put a PDF file in that KM folder
Can we do that with the help of an RFC, can we deal with Links in RFC, is there any such FM??
Regards

I guess you are trying to connect from the R3/ECC to the Portal Server.
Are these two systems in the same network? Do you have usernames (valid and fully authorized) in both systems? What is the OS on which these two systems are housed?
Please provide these details to proceed further.

What is adaptive RFC and How to Use it

hi friends
what is the adaptive RFC
what is the use of it
how we can use it
explain me anyone
and send pdf also
thanks
ramu.

Hi,
To give u a brief idea.
rfcs are used to call data from the backend that is R/3.We use the Bapis from the R/3 system which have some pre defined functionality and data is populated in the correspoding ui elements in webdynpro interface.earlier Rfcs were used but now we have adaptive rfcs in which
if there are changes in the backend(R/3 system) such as changes in the datatype,structures,fields would be automatically be refllected in the rfcs and there would be no errors in web dyn pro even if there is a change in the back end
to be more specific folow this link
http://help.sap.com/saphelp_nw70/helpdata/EN/41/38bc8f813719488ddc9d9b21251ec3/frameset.htm
and try out this application
to use the rfcs firstly check out this document for configurations
