What is RFC and IDOC Adapters in XI ?

Hi,
What is the RFC and IDOC Adapters in XI , in which scenarios we use this adapter , what is the advantages and disadvantages of RFC , IDOC ? can any help me out.
Thanks & Regards

Surendra,
What is the RFC and IDOC Adapters in XI :
IDOC: Generaly standard IDOCs are used to update the data in R/3 or to extarct the data from R/3.
RFC: Are generally used for synchronoue scenarios.
in which scenarios we use this adapter
For example you can use the IDOC ORDERS05 to post the sales orders.
Similarly you can use BAPI_COMPANY_GETDETAILS to fetch the company details.
what is the advantages and disadvantages of RFC , IDOC ?
Advantages: Both can be used for data retrival and posting. RFC can be used for synchronus purpose but IDOCs are always asynchronous.
Disadvangages: If you are using custome made RFC/IDOC then you have to import the RFC/IDOC into XI every time when you make any small changes in the structure.
Also go through this blog to choose the right adapter to integrate with SAP systems.

RFC and IDoc

Hello
Both RFC and Idoc adapters are used to connect to SAP system from XI. Why is that we have to configure RFC Destination, port and partner agreement for Idoc while we do not have to do that for RFC ? Both use the same RFC protocol still we do the configurations only for Idoc. Can someone explain to me the technical reasons why we do that
Thanks
Radhika

Hi,
RFC Adapter resides in Adapter Engine,
IDoc resides in I.E,when you triiger an IDoc it directly Hits I.E,like communication with Other SAP System.
Thats why we need to create the port .....details for IDoc.
But coming i future it IDoc adapter ,HTTP Adapter moving in to JAVA Stack,wait till 2010 july.
in PI7.1 EHP1 there are too many changes in Idoc adapter,like Idoc package we can do at Sender IDoc adapter level.

What is rfc. and uses

what is rfc. and uses

Hi,
RFC
Remote Function Call:
RFCs are requests that an SAP component sends to invoke functions on remote systems, or calls that remote systems initiate to invoke functions on an SAP component.A process that can accept RFCs from SAP components. This allows SAP components to access functions in external systems. In SAP BC terminology, the process is called a Listener. Listeners are one or more threads on SAP Business Connector that wait for incoming requests from SAP components. Listeners are named and register with an SAP gateway to indicate that they are ready to accept requests. Listeners can accept RFC or tRFC requests.
Transactional RFC (tRFC) and Queued RFC (qRFC). tRFC is used mainly to transfer ALE Intermediate Documents (IDocs).
Transactional RFC:
If an error occurs during a synchronous remote function call, the system cannot tell at what point the error occurred (most crucially, whether the function module was actually processed in R/3 before the operation failed). Restarting a failed call is therefore a dangerous thing to do, since you risk duplicating a completed function call.
To alleviate this problem, you can use transactional RFC, which guarantees that each function call you issue will only be executed once, even if you submit it repeatedly to the R/3 System. The system implements this safeguard by assigning a unique transaction ID (TID) to each transaction that you submit. When you attempt to process the transaction, the system checks whether that TID has already been processed. If it has, the transaction is ignored.
Queued RFC:
When you use transactional RFC, you cannot guarantee the order in which the function calls will be processed in the system (it is quite possible that one call might overtake another). For cases where you need to specify a particular processing order, you can use queued RFC, which is an extension of transactional RFC. In qRFC, you place each function call in a logical queue. A function call cannot be executed until all of its predecessors in the queue have been processed. Queued RFC calls are processed asynchronously.
RFC is an SAP interface protocol. Based on CPI-C, it considerably simplifies the programming of communication processes between systems.
RFCs enable you to call and execute predefined functions in a remote system - or even in the same system.
RFCs manage the communication process, parameter transfer and error handling.

Regarding rfc and idoc sender

hi
   can any one provide me with some scenarios having
idoc and rfc as senders.

Hi
To Configure the RFC to FILE scenario ,Proceed as Follows
a.       Create an RFC Destination to XI in transaction code (SM59)
b.       Create new destination of type T (TCP/IP)
c.       Make sure you select Registered Server Program option before writing your program ID
d.       Write you program ID (remember it's case-sensitive)
e.       In the gateway host and gateway service write the values of your Application system - business system (not the XI server)
             Step2:Repository
1)       From the Integration Builder page, select Integration Repository. This will launch the Java Web Start Application. Log with the User id and password from the Integration Server
2)       Choose Tools->Transfer from System Landscape Directory->Import Software Component Versions
         From the list of Software Component Versions, Choose your own software component version .Click Import.
3)       On the left hand side frame ,software components will appear .Select your own software component. Open your own software component. Double click on this software component. A screen will appear .Switch to display mode. After doing this first add a namespace under Namespaces.
         The namespace is ur:rfctofile
4)       Then choose the Radio Button ->Import of RFC AND IDOC interfaces from SAP systems permitted
         After this specify the connection parameters to the R/3 system:
4.1)     System IS :sapfox
4.2)     Client IS :800
         Then Save it. The new namespace will be visible under software component version node in the left frame.
         Under the namespace node, you will find the section Imported Objects. Right click on it and choose Import of sap objects. A wizard will display. In the wizard provide the following details.
4.3)     Application server:172.25.5.7
4.4)     System number: 00
4.5)     User name:developer
4.6)     Password: Password of Sap R/3 system.
         Then click continue .You will find IDOC and RFC node. Click on this node and select the   Idoc or Rfc which is to be imported from R/3. Click Finish to start the Import. Close the wizard. After doing this the   Rfc and Idoc will be available into XI as Message types. So no need to create any Rfc or Idoc Structure. We need to create a structure for file only.
5).      Under your namespace in the left frame, expand the node Interface objects. You will find a node DATA TYPES
6)        Create new data types.
6.1)      Right click on Data types and select New.
           Your Data Type is. dt_file
          In the data type Editor ,Create a structure having Elements of type String , integer, Boolean , Float etc as per the requirement.
          Save the object.
6.2)      The Import function for XSD files enables you to upload message definitions from external sources. The object type External Definition is a container to make external definitions available in the Integration Repository.. While Importing the XSD files from External Definition
          no need to create Data types. They are imported directly as Message types.
6.3)      To do so, In the left hand frame Under Interface objects Create a new object of type External Definition and give name to it.
          Select the following.
6.3.1)    Category: XSD.
6.3.2)    Messages: From All Available Global Elements.
6.3.3)    File:
          Once the XSD is imported, click on Message tab , You should be able to see 2 messages(Request and Response)
7).      Create a new Message Type.
7.1)     In the left hand frame under Interface objects, right click on the Message types and select new.
7.2)     Give a suitable name to the Message type.(MT_ messagetype).
7.3)     For the section Data type used you can go to input help (F4) or Search help provided and choose your data type (DT_datatype) from there.
         Save it.
8).     Create a Message interface
8.1)    In the left hand frame under Interface objects, right click on the Message Interface and select new and name(MI_ messageinterface) it
8.2).   The interface Should be Inbound and mode should be Asynchronous .It should reference your Message type(Use F4 or Search help).
        Save it.
9) .    Create a graphical mapping between the target document and the sender .
9.1)    In the left hand frame ,expand Mapping objects. Right click on Message mapping and name it.You are now in a graphical editor.The Source message is on left, the Target message is on right.
9.2)    As Source message select your own Message type.You can choose Search for Integration Object.As a reminder you can find your Idoc or Rfc under Software Component- >     Namespace->Imported Objects.
9.3)    As Target Message you can choose your Rfc .Choose Search for Integration Object.
9.4)    Now that we have defined the Source and Target message, we can start defining the Mapping rules.
9.5)    Map the fields of Source document to the equivalent fields in Target document .This can be achieved easily by locating the field in Target document and then Drag and Drop the   Source fields to the respective Target Fields.
        Save It.
9.6)    You can also Test your Mapping by selecting the 'Test Tab'.
9.7)    Fill in the values in the Idoc fields and click 'Start Transformation'. On the right hand side you will see Target Document populated with the appropriate Values.

           Create an Receiver Determination.
7).       From the left frame Create a new Receiver Determination object. This is the main part of routing process, where you assign a receiver for your message.
7.1)      Select your sender service and interface.
          Sender:
          Party: blank
          Service: Sender service(Business system)
          Interface : Sender interface
7.2)      In the Configured Receivers area , choose the Service for the Target System.. Save your Receiver Determination
            Create an Interface Determination.
7.3)       Next create an Interface Determination object. Now that we have defined a receiver of message ,we need to assign an Inbound interface and an Interface mapping
7.3.1)     In the Receiver Determination   you just created, have a look at the area Configuration Overview for Receiver Determination   at bottom of your screen and press Refresh for that the Business system you assigned is displayed in that area as well.
7.3.2)     In the column Receiver(Partner/Service) open the details by clicking the node .The Entry Not defined shows you that there is no interface determination present.
           Right click on the Entry Not defined and select New specific, in order to create a new interface determination object
7.3.3)     You are now in the screen Edit Interface Determination. In the section Configured Inbound Interfaces select the Inbound Interface using F4 help Provided. You might need to choose ALL button for the interface to be shown.
           After choosing the Inbound Interface, It is shown in the Interface Determination
7.3.4)     A mapping has to be specified .Use the F4 help next to Inbound Interface to select your Interface Mapping.
7.3.5)     When you are done , Save the Interface determination object.
8.)         Create a Sender Agreement.

What is the difference between rfc and idoc

hi,
My name is rambabu.can anyone of u please tell me the main differences between idoc and rfc??
Thanks in Advance

hi Ramesh,
Remote Function Calls (RFC) and data exchange through IDoc
message documents. RFC makes direct and synchronous calls of a program in
the remote system. If the caller is an external program it will call an
RFC-enabled function in R/3 and if the calling program is the R/3 system
it will call an RFC-function in another R/3-system or it will call a
non-R/3 program through a gateway-proxy (usually rfcexec.exe). BAPIs are
a subset of the RFC-enabled function modules, especially designed as
Application Programming Interface (API) to the SAP business object, or in
other words: are function modules officially released by SAP to be called
from external programs.
IDocs are text encoded documents with a rigid structure that are used to
exchange data between R/3 and a foreign system. Instead of calling a
program in the destination system directly, the data is first packed into
an IDoc and then sent to the receiving system, where it is analyzed and
properly processed. Therefore an IDoc data exchange is always an
asynchronous process. The significant difference between simple RFC-calls
and IDoc data exchange is the fact, that every action performed on IDocs
are protocolled by R/3 and IDocs can be reprocessed if an error occurred
in one of the message steps.
While IDocs have to be understood as a data exchange protocol, EDI and ALE
are typical use cases for IDocs. R/3 uses IDocs for both EDI and ALE to
deliver data to the receiving system. ALE is basically the scheduling
mechanism that defines when and between which partners and what kind of
data will be exchanged on a regular or event triggered basis. Such a
set-up is called an ALE-scenario.

Problem in Import of RFC and IDoc interfaces

hi,
i am a beginner in XI. now am following the link given below.
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/e07dcaa0-a92b-2a10-3a96-b3d942bd1539
Topic: A Step-by-Step Guide on IDoc-to-File Using Business Service in the XI Integration Directory
i don't know how to Import S/W Component and IDoc structure.
my doubt is what should i select from the populated list.
plz help me.
thanks in advance

hi,
Please follow below steps assuming that the Software component is properly created in SLD.
1. open Integration Repository (IR)
2. Goto ---> Tools -
> Trasfer SWCV from SLD
3. Select the Software Component from the pop-up list
4. Press Import
5. It will import the software component in IR
6. Save it and activate.
7. If its for SAP system then give RFC details in SWC
8. Create Namespace in it and save and activate
http://help.sap.com/saphelp_nw04/helpdata/en/9c/7a973ca83a4601e10000000a114084/content.htm
Now it will be ready for further Development.
For importing an idoc structure...
go to imported objects and right click there and select import iDOCs and there give your application system details.This is the way to import your IDOc structure.
Thanks,
Vijaya.

When and Why we use BAPI, RFC and IDOC.. in XI

Hi,
Could any one tell me why we some time use BAPI, and some times use RFC and some times use IDOC while communicating with the SAP systems.
Is there any differences while using the same.
regards,
Sunil

Sunil,
RFC and BAPI are same as per the technical point of view both are remote enabled function module..
BAPI is provided by SAP while RFC is created by a developer..
IDoc is another proprietary technology of SAP for exchnaging messages .
Difference lies here :
1. For RFC/BAPI you need to use RFc adapter
while for IDoc you need to use IDoc adapter..
2. For RFC you need to create RFC destinations not for Idoc
3. For Idoc you also need to manage Partners Profiles..inn R3..
These are few differences in using RFC/BAPI and Idoc...not the only ones..
Feel free for any clarification..
Regards,

Problem when calling the RFC and IDoc adapter at the same time

Hi,
I'm having a major slowdown problem with XI3.0 SP11.
When I'm sending a message(IDoc) from R/3 into XI to get translated into an EDI document, I have no problems and it's very fast. RFC calls are very fast too.
Now, if I'm sending the same message and at the same time another call is done trough the RFC adapter, then the full XI environment hangs for several minutes.
I did all recommended settings from the XI-SR1 install guide(Configuring the J2EE Engine) and tuning guide (XI Configuration Parameters)
and I don't know what to do more? At the Unix level, command TOP shows that dw.sap.XDV_DVEBMGS70 is taking all the CPU% available when both messages(IDoc and RFC) are sent to XI at the same time.
Anybody have an idea what to do next?
Rgds,
Yves

Did you check the dev_rfc logs ? Also check SM21 for any errors. Logon to the Target System and check SM50 transaction then you will know whats going on.

Shravan

What is ale and idoc after small explanation

plz send me reply

Hi,
Check this info.
ALE
ALE means of creating and operating distributed applications.
Application Link Enabling (ALE) guarantees a distributed, but integrated, R/3 installation. This involves business-controlled message exchange using consistent data across loosely linked SAP applications.
Applications are integrated using synchronous and asynchronous communication - not by using a central database.
ALE consists of the following layers:
Application services
Distribution services
Communication services
Refer
http://www.sappoint.com/abap/ale.pdf
http://www.sappoint.com/abap/ale2.pdf
Check this link ALE and EDI
IDOC
IDoc is a intermediate document to exchange data between two SAP Systems.
*IDocs are structured ASCII files (or a virtual equivalent).
*Electronic Interchange Document
*They are the file format used by SAP R/3 to exchange data with foreign systems.
*Data Is transmitted in ASCII format, i.e. human readable form
*IDocs exchange messages
*IDocs are used like classical interface files
IDOC types are templates for specific message types depending on what is the business document, you want to exchange.
WE30 - you can create a IDOC type.
An IDOC with data, will have to be triggered by the application that is trying to send out the data.
FOr testing you can use WE19.
How to create idoc?
*WE30 - you can create a IDOC type

http://www.sapgenie.com/sapedi/idoc_abap.htm
http://www.erpgenie.com/sapedi/idoc_abap.htm
To Create Idoc we need to follow these steps:
Create Segment ( WE31)
Create Idoc Type ( WE30 )
Create Message Type ( WE81 )
Assign Idoc Type to Message Type ( WE82 )
Creating a Segment
Go to transaction code WE31
Enter the name for your segment type and click on the Create icon
Type the short text
Enter the variable names and data elements
Save it and go back
Go to Edit -> Set Release
Follow steps to create more number of segments
Create IDOC Type
Go to transaction code WE30
Enter the Object Name, select Basic type and click Create icon
Select the create new option and enter a description for your basic IDOC type and press enter
Select the IDOC Name and click Create icon
The system prompts us to enter a segment type and its attributes
Choose the appropriate values and press Enter
The system transfers the name of the segment type to the IDOC editor.
Follow these steps to add more number of segments to Parent or as Parent-child relation
Save it and go back
Go to Edit -> Set release
Create Message Type
Go to transaction code WE81
Change the details from Display mode to Change mode
After selection, the system will give this message The table is cross-client (see Help for further info). Press Enter
Click New Entries to create new Message Type
Fill details
Save it and go back
Assign Message Type to IDoc Type
Go to transaction code WE82
Change the details from Display mode to Change mode
After selection, the system will give this message The table is cross-client (see Help for further info). Press Enter.
Click New Entries to create new Message Type.
Fill details
Save it and go back

What is RFC and how does work

Hi Sap Guru's
I want to know the RFC in SAP and how does it work?
Thanks in advance
Regards
Ramesh

Hi Ramesh,
These are the types of RFC
Asynchronous RFC (aRFC)
Synchronous RFC (sRFC)
Transactional RFC (tRFC)
Queued RFC (qRFC)
Parallel RFC (pRFC)
Asynchronous RFC :
This is used when you need to increase the performance of ABAP program by having system call more than one function module in parallel than forcing the program to wait for results .
Transactional RFC
This let you group one or more function module call together o tRFC LUW and ensure that fucnction module within LUW is called once . In contrast to aRFC and sRFC the tRFC belonging to tRFC LUW are executed in order .
tRFC is always used if a function is executed as a Logical Unit of Work (LUW). Within a LUW, all calls are
1.Executed in the order in which they are called
2.Executed in the same program context in the target system
3.Run as a single transaction: they are either committed or rolled back as a unit.
Implementation of tRFC is recommended if you want to guarantee that the transactional order of the calls is preserved
Asynchronous remote function calls (aRFCs) are similar to transactional RFCs, in that the user does not have to wait for their completion before continuing the calling dialog. There are three characteristics, however, that distinguish asynchronous RFCs from transactional RFCs:
When the caller starts an asynchronous RFC, the called server must be available to accept the request.
The parameters of asynchronous RFCs are not logged to the database, but sent directly to the server.
Asynchronous RFCs allow the user to carry on an interactive dialog with the remote system.
The calling program can receive results from the asynchronous RFC.
You can use asynchronous remote function calls whenever you need to establish communication with a remote system, but do not want to wait for the functions result before continuing processing. Asynchronous RFCs can also be sent to the same system. In this case, the system opens a new session (or window). You can then switch back and for between the calling dialog and the called session
RECEIVE RESULTS FROM FUNCTION Remotefunction is used within a FORM routine to receive the results of an asynchronous remote function call. The following receiving parameters are available:
IMPORTING
TABLES
EXCEPTIONS
The addition KEEPING TASK prevents an asynchronous connection from being closed after receiving the results of the processing. The relevant remote context (roll area) is kept for re-use until the caller terminates the connection.
Hope this resolves your query.
Reward all the helpful answers.

Use EOIO on Sender RFC and outbound ABAP proxy calls

In the comm channel of SOAP and FILE there is a simple flag to set for QOS = EOIO
In Plain HTTP adapter a QOS parameter can be supplied.
IDOC uses control record tricks or a Receiver adapter option.
But what about the RFC and XI adapters.
The docu states QOS of EOIO for RFC and XI adapters is possible.
How is set for sender RFC and Sender XI adapters?
regards
Phil

Phil,
I was discussing with Michal about this.
I suppose it is not fully EOIO, because you don't send directly from the outbound queue to the inbound queue. The AE service may not have a specific queue for that message, until the queue is associated in adapter module. Maybe (just maybe), if you get unexpected extra processing in the initial AE reception of the message (and hence, before the queue is set, in adapter module), you may have some inconsistencies with the processing order in sender system.
But again, that is just a speculation.
I'm not sure what is the behavior it'll have.
And even if what I speculated is right, it is a really short amount of time.
But again, EOIO would not be 100% guaranteed (maybe 99% hehe).
But sometimes (most of the times) that is not enough.
Regards,
Henrique.

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)

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.

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 to IDOC

Hi,
My scenario is RFC to IDOC
When the IDOC is received it triggers the Create/change sales document program.
for Create i have 1 Custom IDOC and for Change/deletion i have another IDOC.
The inbound IDOC should be able to handle Creation/Change and deletion.
already i have imported RFC and IDOC's
So, could you please confirm me once again...the procedure in IR and ID

RFC to IDOCs

Hi Experts,
I have a scenario for RFC -- XI -- IDOC
In my XI dev. system already i have imported RFC and IDOC's
I have 2 Custom IDOC's
First IDOC is for Create
Second IDOC is for Change/Delete
Based on the condition i should select either one of the above IDOCs.
So, How many Message Mappings shall i need to create or
If i import both IDOCs at Receiver side and can i do the Mapping.
Awaiting for your response and Reward points for helpful answers...
Thanks & Regards,
Ramana Kumar. A

Thanks Varun,
based on the condition here,
field1 map with E1EDK03 (field: IDDAT) and the description here is, Fixed value = 001 set up in connection with the next field.
Here i map constant 001 to E1EDK03 node
Is this correct?
Next Field here is DATUM and the desc. here is If = `1´ then map date from field1 else if `blank`
field2 map with E1EDK03 (field: IDDAT) and the description here is, Fixed value = 002 set up in connection with the next field.
Here i map constant 002 to E1EDK03 node
Is this correct?
Next Field here is DATUM and the desc. here is If = `1´ then map date from field2 else if `blank`
