Custom Idoc or RFC

Hello,
In XI Interface File Adapter pick the data and it needs to sent to SAP R/3 to create Measurement Document.
Should I create Custom IDOC import into XI and by using IDOC Receiver Adapter send data to SAP R/3 and through Posting Program create Measurement Document.
Should I create Rempte Enabled RFC and use RFC receiver Adapter and through Function Module create Measurement Document.
Pls suggest

Hi henry,
there are various ways;
1. IR or ID Goto Menu -> Help -> INformation
2. XI start page -> Administration -> Software Build Information
and regarding RFC and Idoc we have already answered u!!!
now check ur WAS version...if its >=6.2 use proxy if not use RFC.....
ok see here...
Advantage of Proxy over RFC, IDOC

How to trigger automatically an IDOC and RFC from SAP R/3 system?

Hi ,
lets say if we are implementing IDOC to FILE &RFC to FILE scenario ,how can we trigger on timely basis(schedules)
1)standard IDOCs and BAPIs?
2)customized Idocs and Customized Bapis?
3)Master Idocs and transactiona Idocs?I think we need to use change pointers for master Idocs and donno about Transactional Idocs.
please explain ,
thank you very much for your help.
regards,
Babu

sorryfor the late reply, I was busy with my work.thank you for your posts.
so all of you say just run the RSEOUT00 no matter what interface we use in XI like Master ,transactional Idocs,standard or customized BAPIs?
And I think we use RSNASTED if we have on recieving side right?
<b>then when we would use a report of format below to trigger an RFC,is this format for Asunc RFC ?</b>
REPORT Z_SEND_DATA_TO_XI.
parameters: dest like rfcdes-rfcdest default '(RFC Destination you defined in SM59)'.
<<your other variable declaration and ABAP Code here>>
call function 'ZXI_SEND_DATA'
in background task
destination dest
exporting
Name = John
City = Smith. (The values to pass to XI)
commit work.
<<Any Write statements or sy-subrc statements here>>
6) Save and Activate your ABAP program.
6) After all these steps, execute your ABAP Program to send the data to file via XI.

Procedure for Mapping two types of Idocs from RFC function Module

Hi
My Scenario is RFC -- XI -- IDOC
Here i have 2 custom Idocs
First IDOC for Creation
second is for Deletion/Changing
Based on the condition from RFC it should trigger either one of the IDOC above.
Please provide me the procedure to do in IR and ID..
Regards,
Yeswanth.

YeswanthRaj:
I found your conflicted statements
The following statement you say you just have one receiver, to receive two IDOCs
But i have only one receiver where the 2 IDOcs needs to be send based on the condition..
The following statements showing that you have more than one receiver,
the condition editor for receiver determination usually used for multiple receivers based on XPATH or Context Object condition
It is mapped based on the condition that is given in Receiver Determination and i has two interface Determinations.
It seems that the first scenario is your situation.
If your answer is yes, and your source interface is just one,and target interface is two (two IDOC), then this should be typical
muti-mapping scenario, and the propose I gave to you should fit
Regards.

ALE/IDOC and RFC/BAPI Integration Scenarios with SAP DS for ESA v3

Hi,
we are planning two PoCs of Integration Plattforms. One of our major requirement set is SAP Integration into our existing SOA.
Because we also have R/3 4.7 Systems in production, we are planning to test ALE/IDOC and RFC/BAPI Integration scenarios with these Integration Plattforms.
My question is:
We are looking for are smart solution to get a SAP Test Environment, where we can test ALE/IDOC und RFC/BAPI Integration scenarios.
It is possible to do this with SAP DS for ESA v3 or shall we better use IDES for that purpose?
Best regards,
Steven

Hi Abhishek,
This is our scenario. We are doing an integration of SAP HR r/3 system with the CRM system. We need housing information details of the employees which we have in custom infotype 9310 in SAP HR system and we need those details in the CRM system. So am planning out for an ALE/IDOC approach for the integration and gonna maintain the 9310 details in a custom table. In the CRM system, we gonna build a BOL layer for accessing the 9310 details. Also i'm preparing a HLD for this process. I wanna read and go through few same HLD's before i submit my proposal to my client. Please suggest me and help me out.
Thanks in advance.

Difference between idoc and rfc

what is the difference between idoc and rfc? when and where it is used? when there is idoc, why rfc vice versa?

IDoc (for intermediate document) is a standard data structure for electronic data interchange (EDI) between application programs written for the popular SAP business system or between an SAP application and an external program. IDocs serve as the vehicle for data transfer in SAP's Application Link Enabling (ALE) system.
IDocs are used for asynchronous transactions: Each IDoc generated exists as a self-contained text file that can then be transmitted to the requesting workstation without connecting to the central database.
Another SAP mechanism, the Business Application Programming Interface (BAPI) is used for synchronous transactions.
A large enterprise's networked computing environment is likely to connect many geographically distributed computers to the main database. These computers are likely to use different hardware and/or operating system platforms. An IDoc encapsulates data so that it can be exchanged between different systems without conversion from one format to another.
IDoc types define different categories of data, such as purchase orders or invoices, which may then be broken down into more specific categories called message types. Greater specificity means that an IDoc type is capable of storing only the data required for a particular transaction, which increases efficiency and decreases resource demands.
An IDoc can be generated at any point in a transaction process. For example, during a shipping transaction process, an IDoc may be generated that includes the data fields required to print a shipping manifest. After a user performs an SAP transaction, one or more IDocs are generated in the sending database and passed to the ALE communication layer. The communication
layer performs a Remote Function Call (RFC), using the port definition and RFC destination specified by the customer model.
The IDoc is transmitted to the receiver, which may be an R/3, R/2, or some external system
RFC
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.
note:reward points if solution found helpfull.....

How to import Custom idoc into IR?

I have a custom idoc and i need to map it with the receiver format after importing into IR . Please let me know the sequence of steps to import custom idoc into Integration repository?
I think I need to first import into IDX2 and then import into repository. Am I correct?

Hi Prateek,
thanks for the information .The normal standard idocs we import by searching the idoc eg- for importing matmas we type mat and we search it, since it is a standard idoc it will be available in the list (after selecting the chek box "Import of idoc or rfc interfaces from sap system permitted").
But my question is how we import custom idoc as they wont be present in the list?

Error in File to Custom IDoc

Hi All,
I am getting following error while doing File to Custom IDoc Scenario
No authorization to send IDocs with message type Z
Can any one tell how to resolve this error?
Regards,
Sai

Hi Krishna,
The RFC destination that you have put in IDoc communication channel must be present in your SAP XI system, transaction SM59 also.
Please check if the user id/Password that you have given has all the authorization.
Also check the User ID and passwrord in SM59 in R3 and see if a Remote Login is possible.
There is also some configuration by which the clients are allowed / blocked from receiving Idocs from XI. Basis guys can do it for you. Please approach your basis consultant. Hopefully that helps..

Abhy

Idoc to RFC scenario

Hi,
I have four Sap system connected with PI 7.0 .
SAP1 --> PI --> FILE (SAP2)
--> FILE (SAP3)
--> RFC (SAP4)
The system SAP1 send to PI a custom Idoc; PI tranform Idoc in flat file for system SAP2 e SAP3. The system SAP4 requires sending data via RFC function.
What are the steps to follow to call the RFC function once for each IDOC segments?
Thanks
George

Hi
When the RFC is receiver,no need to configure special settings except RFC receiver communication channel.
During the creation of receiver communication channel need to provide all receiver system details including RFC :

File to custom IDOC or File to abap proxy

Hi there,
I would like to know best approach for the following scenario.
1) i have file coming from legacy system
2) On target side SAP , I have BAPI's available (Create, Save, Commit )(No standard IDOC available)
I can create Custom IDOC and call those BAPI's in Custom Function Module
or
I can use ABAP proxy and call BAPI's
What is the best way of doing this? and Is there any other way?
Thanks
Kumar

hi,
Abap Proxy is better than RFC in terms of performance.
proxy is that it always by passes the Adapter Engine and will directly interact with the application system and Integration engine - so it will and should give us a better performance.
In your case , if there want to crate idoc from scratch level then we go for proxy and proxy support large volume of data (more than 5 mb).
One more reason is RFC , the data is converted between RFC and XML in RFC adapter. In proxy XI communicates with the R/3 in native XI language (SOAP XML).

IDOC and RFC sent by SAP PI , how to access in ECC.

Hi Everybody,
I have been working in SAP PI but have never handled the ECC part of the implementation.
Till now I have only dropped idoc or RFC to the ECC system and let the further processing to the target team.
But in new project the further processing part also we have to handle.
So could you please tell me, for any idoc (say ORDERS) once PI drops it at ECC , where to access it ? which table? for further processing of that data in ECC? Same for RFC?

Dilip, as soon as the system ECC receives IDOC file, IDOCs are created. For further processing
1. ALE attributes (BD51) must be defined.
2. Then Partner profile (WE20) must be active for the partner(vendor/customer) and message
(ORDERS/DESADV) combination which exists in IDOC control record.
3. If you want to manually process IDOC in test or dev system you can use test tool (WE19).
4. To monitor created IDOCs you can use WE02/WE05.
5. You can use tables EDIDC, EDID4, EDIDS to view IDOC info.
6. Also you can go to corresponding tcode to see the posted document.
Thanks,
Siva

Difference among IDOCS,BAPI,RFC?

what is the difference among IDOCS,BAPI,RFC? and what is the real need to use them and again where exactly these are used in real time applications?

Hi,
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.
IDOC type and IDOC. An Intermediate Document (IDOC) type represents the structure of the data associated with a message type (DEBMAS02 for message type DEBMAS Customer Master, and WMMBID02 for message type WMMBXY Goods Movements), while an IDOC is an object containing the data of a particular message type. IDOCs are data containers with intelligence built in. Each IDOC contains one and only one business object. For example, an IDOC of type SHPMNT01, message type SHPMNT, will contain data only of one Shipment Document. Generally, the architecture of an IDOC is independent of the message type by virtue of ALEs ability to redefine it for any message type.

Creating custome idocs

hi all
I am XI consultant
i want to send IDOC to XI server using ALE..but the IDOC is not present ....the master data is stored in standard sap tables but for them idoc is not present ...so i want to create custom idoc and using change pointer i can send it across ...is this a write approach...? Also please give me the procedure for the above approach as i dont have idea about how to create custome idoc and send it using change pointer
thanks

Hi
Data Creation in Idoc
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.
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.

An IDoc is simply a data container that is used to exchange information between any two processes that can understand the syntax and semantics of the data...
1.IDOCs are stored in the database. In the SAP system, IDOCs are stored in database tables.
2.IDOCs are independent of the sending and receiving systems.
3.IDOCs are independent of the direction of data exchange.
The two available process for IDOCs are
Outbound Process
Inbound Process
AND There are basically two types of IDOCs.
Basic IDOCs
Basic IDOC type defines the structure and format of the business document that is to be exchanged between two systems.
Extended IDOCs
Extending the functionality by adding more segments to existing Basic IDOCs.
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)

Idoc or RFC

Dear Guys
Will some body explain the relationship between IDOC BAPIS and RFCs. I have developed a interface between SAP 4.6C and ASP.NET using .NET Connectors. When I am getting data by just using RFC then why should I go for IDOCs.
My same is question is related to BAPIs when RFCs Function using BAPI are providing me data through BAPIs then why is IDOC technology there.
When I have to use RFC and when we can use IDOC or RFCs.
Basically I am trying to develop an ASP application by using which our customer can crreate Sale Order on SAP.

hi,
>>>How does it work in real life scenarios? Will there be a batch job to trigger the IDOCS to XI?
yes but you can set IDOC creation from PO
in a few minutes (in standard) and you
have to do a lot a development to send
them with RFC... so not few minutes
+ you can archive idocs and delete them
just like any message in the XI
>>>>2) How can i create an IDOC?
you have to maintain the partner profile and
set the output type and that's all...
5 minutes in standard
3) What is the RFC involved to get the purchase orders?
none you have to fill the RFC yourself...
you can use BAPI for PO creation as a template
but you still have to fill it youself
