Idoc and change pointers question.

Hi everybody,
How can I create a change pointer automatically for a change document on table JCDS? Becuase I can create change pointers for the change documents on table CDHDR, but I need to catch a technical object status change and create an idoc for the object that changed its status.
Thanks,

Hi Fernando,
I'm trying to accomplish the same thing that you were... trying to get a change pointer to be created based off the status change of a technical object (functional location or equipment).
Can you give me any detail on what you did?
Thanks,
John

ALE Idoc Change Pointers Question

Though I selected Transfer Immediately on Partner Profile screen, why Idoc hasn't been generated and transmitted?. Why do I have run RBDMIDOC explicitely to pickup change pointers?. Appreciate your responses.

Hi Appana,
Thank you for your time. I did checked all these steps still no luck.
1.Go to the Data Element of the field and check whether change doucment option is checked or not .
DONE
2.change the value of the field and check the entries in CDHDR and CDPOS.here u can check the change document object and table .
DONE
3.check BDCP table also incase of ALE.The program RBDMIDOC generates IDOc when there is an entry in BDCP.
if not check the following config
1.BD61- change pointers activated -generally
DONE
2.BD50 -Activate change pointers for ur message type
DONE
3.BD52 - add the triggering fields and corresponding tables and change document object.
DONE
Please check the entries in BDCP table ,if u find the entries execute the program RBDMIDOC
DONE
Any places I missed ? Please note usual ALE config has been done like SM59,WE,20,WE21 etc. Iam basically sending this Idoc to XI and then to 3rd party system.

Trigger IDOC using change pointers

Dear All,
We are using change pointers for triggering IDOC's when a cost centere is creaed/changed/deleted.
We are using message type COSMAS for the same.
I have maintained all the necessary settings including Distrubution model.
When a cost centre is created or changed the IDOC is getting triggered ( After executing prgroam RBDMIDOC ).
But when we delete an cost centre the IDOC is not getting triggered.
I am able to see the releated entries in BDCP and BDCPV tables as well as CDHDR and CDPOS tables.
Can any one say how this can be achieved? When a cost centre is deleted then also IDOC should get triggered.
Regards,
SRavan

When we remove an Cost center it physically gets deleted from the data base.There is no delete indicator as such

IDOC HRMD_A + Change pointers + Infotypes change objects doesnt exist???

Hi guys,
I Have to send master data from infotypes 0002, 0006, 0032 and 0105 from HR to SAP PI. I've configured BD61, BD50 and BD53 to reduce Idoc HRMD_A. Then in BD52 I've tried to put this fields to activate change pointers when data from this infotypes is changed.
But in BD52 doesnt exist infotypes 0002, 0006, 0032 and 0105. I tried with object HR_IT1002, table HRP1002 and fields BEGDA and ENDDA, then run program RBDMIDOC and the Idoc is sent, but is possible with infotypes metioned????
Regards,
Pablo

Pablo,
are you able to see entries getting created in BDCP* tables
did you activate change pointers in BD53
Thanks

Sending Idocs from Change pointers

Hi All,
When using RHALESMD or RBDMIDOC, is it possible to send Idocs with transfer mode Insert instead of Update?
Currently when I create new P objects and run the programs the Idocs sent is of transfer type Update. But since the object doesn't exist in receiving system there is nothing to update.
Please let me know if you have any thought what action i can take to solve this problem.
Best regards
Mikael

Dear Karyna,
The data is fetched from tables TBDME and TBDA2. Neither of the tables has partner system.
You can use below parameters by copying the program and modifying as per your requirement. See if you can link them to receiver partner system.
The data is fetched from TBDME.
You can use below parameters.
MESTYP     Message Type
REFMESTYP     Reference message type
IDOCFBNAME     ALE: IDoc editing function module
OBTAB     Name of database table for object
CREUSER     Created by

BD10 and change pointers

I'm new to using BD10 to create MATMAS Idocs.
I've set up change pointers, created a change document and then run BD10. The IDOCs I expected were created just fine.
However, the BD10 transaction continues to create new IDOCs every time I run it, even though I haven't made any new changes to the materials.
Is this behavior normal?
I'd like to have the IDOCs created only once.

Hi Ed,
BD10 is for sending material, regardless of any change.
Use BD21 to process change pointers.

Frank Umans

Table maintenance generator and Change pointers

If a Ztable contains table maintenance generator, then the change pointers will not work?

Hi Saraoja,
If you want make active your change pointers for your Ztable, then in your Zfields, get into the Data element and click futher Characteristics tab, there you have one check box called Change document, Check that box and activate your data element again.Now your Zfield changes will reflect in CDHDR and CDPOS.

Idoc serialization and change pointers automatic trigger

Hello Experts
How to trigger an Idoc automatically once the application has been saved ?
Scenario 1: Here serialization of message types are used, all the idocs in the serialization group must trigger & sent to the receiving system as per the sequence even if any field in the complete serialization group of message type changes (Note No Manual processing using reports Like RBDSER01, RBDSER02 etc..or Batch Jobs)
Scenario 2: Again Idoc has to trigger and sent to the receiving system as per the change pointer configuration once the application has been saved (Note: No manual processing like BD10, BD11 etc.. and no user exits has to invoke while saving the application).
Please let me know is this two cases can be implemented. Thank you in Advance.

How to send single person-records with HRMD_A Idoc and change Idoc header?

Hello group,
we have different companies in our SAP system (BUKRS). Now when an infotype is changed the changepointers are activated and using program RBDMIDOC we can send Idocs of type HRMD_A to f.i. files. In order to have these files distributed to different parties depending on BUKRS of the person we would like to have HRMD_A to deliver single records, an Idoc for each person and the Idoc header fields for variant and function should be filled so that the partner profile would distribute the Idoc to the partie.
Is this possible? And if yes how?
Regards, Léon Hoeneveld The Netherlands

Transaction PFAL lets me trigger the Idoc manually, but with a job for RBDMIDOC this is automatically.
I found fm RH_HRMD_BLOCK_SIZE in wich you can enhance the code to set the block size for an Idoc-type to 1.
But now I still have to change the Idoc header with an enhancement of user-exit.
HRALE00OUTBOUND_IDOC BADi does not have the functionallity.

Activate change pointers for Z-idocs

Hi friends,
I've created a Z-idoc for some standard SAP tables (like TCJ1T, TCJ05 etc). I've written a function module which fetches all the data from the above-mentioned tables and pass it on to the idoc. So far so good.
Now the requirement is like, I need to pass only the updated records (insert/update/delete) in these tables to the idoc. I found that there are concepts like change document and change pointers assosciated with it. Again, the fields that I need to transfer in the above tables have their change document flag set. I've also created a Z-Object through SCDO to capture the changes. (I initially tried adding the tables in the standard object PROJ regenerated the programs, but the approach didn't work). The function modules generated through SCDO, i guess, have to be called somewhere, may be in an exit (I got an info in a previous question that it is never called automatically, but has to be called explicitly). The entries for most of the tables I'm working with are created via SPRO (which links to the Table Maintainence Generator for the above tables). I found that there are no user-exits for the transactions SPRO and SM30, to call these function modules in the first place.
Change pointers refer to the tables CDHDR and CDPOS, the tables which the change document updates (as found in the function module CHANGE_POINTERS_CREATE). Now, how do I track the updates on these tables, since the change pointers itself is dependent on the change documents and I couldn't find a place to incorporate the function module call that would update the change document tables?
Any help is appreciated.
Thanks & Regards
Anil Madhavan

Hi Anil,
In SM30 you have programmable events:
Environment -> Modification -> Events
Here's the link to documentation teaching how to create change documents:
http://help.sap.com/saphelp_47x200/helpdata/en/2a/fa015b493111d182b70000e829fbfe/frameset.htm
I'm also trying to learn how to access the needed data in these SM30 events so that I can call the function to generate the change document with the right data in SM30
Let me know if this was useful.

Nuno

Need to trigger change pointers for a change in std text

I need to trigger an idoc via change pointers when any change in a std text occurs. I am doing this for changes in Customer Master. For example, if the std text obtained via tcode XD02 is changed, then I need to trigger an idoc. Is this possible? What is the object class used?
Thanks,
Keerthi

Hi,
All Standard text views are stored in V_E071.
Use the View for V_E071 for checking standard text transport
Give Object Filed Name = TEXT and check
And search the standard object
Go to se09 create workbench request and
Double Click the request and go to program give R3TR and Object: TEXT and object Name: TEXT, Nike_FT_AB_4700, ZEPC, D
Object: TEXT
Where Nike_FT_AB_4700 is Customized Name of Standard Text
Text Id: ZEPC (Default: ST)
Language: D (DE)
Go to SE03 double click the Search for Objects in Requests/Tasks in the
R3TR Object ; TEXT and do search.. with respective to that you will get change request.
Do rewards points.

Change pointers

HI All,
Can you guys plz help me on change pointers.
I have activated change pointers for CREMAS and I am running program RBDMIDOC in background. But it is generating idocs properly when ever vendor is created or changed.
Change pointer is triggering for all vendors when ever vendor is created or changed.
Here my problem is that i don't want to generate all idocs i want to generate idocs for some specifi vendors only (Here we are having different types of vendors depend upon Account group.)
How can I generate specific venodr Idocs using change pointers.
Thanks & Regards
Praveen

Hi Praveen,
There are two filtering in IDoc.
Segment Filtering:
Segment filtering can be achieved using T/Code BD56. Here you can suppress a whole segment irrespective of data inside it . You have to give Message Type / Sender Prrtner / Receiver Partner.
Data Filtering:
Data filtering can be done in dustribution model where you can restrict whole IDOCS or partials IDOCS to be send based on data in fields inside IDOC depending on whether the segment in which you filter is at the highest level or at a lower level. For example in MATMAS if you put a filter of E1MARCM for a particular plant , only data for this plant will go and other plants will be ignored.
For your case, you can use segment filter to send only to specific vendor(s).
Please check this link for detail information.

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.

What is IDOC and ALE?

Hi anybody,
 Please tell me what is IDOC and ALE? What pupose using IDOC and ALE?
 Give me Example sample code of using IDOC and ALE.
Thanks

Dear,
Here is some facts which will be helpful to clear yr concepts for ALE/IDOCs.

ALE (Application Linking and Enabling)
Ale Technology is SAPs technology to support distributed yet integrated processes across several SAP systems.
Distributed Process:
A distributed process is one in which part of a business process is carried out on one system and part on another. The two systems would exchange data with each other at appropriate points to stay synchronized.
Need for Distributed Process:
Business in Different Geographical Locations.
Non availability of dedicated network.
Cultural and language differences in Geographical locations.
Running of Mission-critical Applications (Like Maintenance downtime etc.).
Separate up gradation of Modules.
Distributed SAP SYSTEM CHALLENGES
A system that understands the syntax and semantics of the data. It was important from the very beginning to base the distribution of data on business rules, not on database replication techniques.
Distributed systems that can maintain their autonomy while being integrated as one logical SAP system. The systems should be able to operate independently and support logical processing of transactions and data.
Distributed systems that can handle different data models. A local implementation should be able to customize the system to meet its local needs.
Receiving systems that can handle their own problems and not tie up the sending system.
Systems that maintain continued operation in spite of network failure. Changes made to either system should be synchronized after the network connection is restored.
A sound technology and methodology that can be used in all distribution scenarios.
SAP Distributed environment:
ALE allows for efficient and reliable communication between distributed processes across physically separate SAP systems.
ALE is based on application to application integration using messaging architecture. A message defines data that is exchanged between two processes. IDocs are containers that hold data exchanged between the two systems.
Benefits of ALE:
Integration with non-SAP systems: ALE architecture allows third party applications to integrate with SAP system.
Reliable Distribution: Once message type created and the receiver of the message is determined, ALE delivers the message to the recipient. If there is any network problem it will buffer the message and delivers the message once the network is restored. It also ensures that the message is not delivered twice.
Release Upgrade: Any of the distributed system can be upgraded to the new release of SAP without affecting the functionality. The ALE layer ensures backward compatibility of messages exchanged between systems.
ALE Architecture:
It consists of an Outbound process, an Inbound process, and an Exception Handling process.
Outbound Process:
ALE Outbound Process in SAP sends data to one or more SAP Systems. It involves four steps.
1. Identify the need of IDoc: This step starts upon creating a application document, can relate to a change to a master data object.
2. Generate the Master IDoc: The document or master data to be sent is read from the database and formatted into an IDoc format. This IDoc is called as a Master IDoc.
3. Generate the Communication IDoc: The ALE Service layer generates a separate IDoc from the Master IDoc for each recipient who is interested in the data. Separate IDocs are generated because each recipient might demand a different version or a subset of the Master IDoc. These recipient-specific IDocs are called Communication IDocs and are stored in the database.
4. Deliver the Communication IDoc: The IDoc is delivered to the recipients using an asynchronous communication method. This allows the sending system to continue its processing without having to wait for the destination system to receiver or process the IDoc.
Inbound Process:
The inbound process receives an IDoc and creates a document in the system.
1. Store the IDoc in the database: The IDoc is received from the sending system and stored in the database. Then the IDoc goes through a basic integrity check and syntax check.
2. Invoke the Posting Module: The control information in the IDoc and configuration tables are read to determine the posting program. The IDoc is then transferred to its posting program.
3. Create the Document: The posting program reads the IDoc data and then creates a document in the system. The results are logged in the IDoc.
IDoc Types:
IDoc type structure can consist of several segments, and each segment can consist of several data fields. The IDoc structure defines the syntax of the data by specifying a list of permitted segments and arrangement of the segments. Segments define a set of fields and their format.
An IDoc is an instance of an IDoc Type and consists of three types of records.
i. One Control record: each IDoc has only one control record. The control record contains all the control information about an IDoc, including the IDoc number, the sender and recipient information, and information such as the message type it represents and IDoc type. The control record structure is same for all IDocs.
ii. One or Many Data records: An IDoc can have multiple data records, as defined by the IDoc structure. Segments translate into data records, which store application data, such as purchase order header information and purchase order detail lines.
iii. One or Many Status records: An IDoc can have multiple status records. Status record helps to determine whether an IDoc has any error.
Message in IDoc Type:
A Message represents a specific type of document transmitted between two partners.
Outbound Process in IDocs:
Outbound process used the following components to generate an IDoc. A customer model, and IDoc structure, selection programs, filter objects, conversion rules, a port definition, an RFC destination, a partner profile, service programs, and configuration tables.
The Customer Model:
A customer model is used to model a distribution scenario. In a customer model, you identify the systems involved in a distribution scenario and the message exchanged between the systems.
Message control:
Message control is a cross application technology used in pricing, account determination, material determination, and output determination. The output determination technique of Message control triggers the ALE for a business document. Message control separates the logic of generating IDocs from the
application logic.
Change Pointers:
The change pointers technique is based on the change document technique, which tracks changes made to key documents in SAP, such as the material master, customer master and sales order.
Changes made to a document are recorded in the change document header table CDHDR, and additional change pointers are written in the BDCP table for the changes relevant to ALE.
IDoc Structure:
A message is defined for data that is exchanged between two systems. The message type is based on one or more IDoc structures.
Selection Program:
Is typically implemented as function modules, are designed to extract application data and create a master IDoc. A selection program exists for each message type. A selection programs design depends on the triggering mechanism used in the process.
Filter Objects;
Filter Objects remove unwanted data for each recipient of the data basing on the recipients requirement.
Port Definition:
A port is used in an outbound process to define the medium in which documents are transferred to the destination system. ALE used a Transactional RFC port, which transfers data in memory buffers.
RFC Destination:
The RFC destination is a logical name used to define the characteristics of a communication link to a remote system on which a function needs to be executed.
Partner Profile:
A partner profile specifies the components used in an outbound process(logical name of the remote SAP system, IDoc Type, message type, TRFC port), an IDocs packet size, the mode in which the process sends an IDoc (batch versus immediate), and the person to be notified in case of error.
Service Programs and Configuration Tables:
The outbound process, being asynchronous, is essentially a sequence of several processes that work together. SAP provides service programs and configuration tables to link these programs and provide customizing options for an outbound process.
Process flow for Distributing Transactional Data:
Transactional data is distributed using two techniques: with Message control and without message control.
Process flow for Distributing Master Data:
Master data between SAP systems is distributed using two techniques: Stand alone Programs and Change Pointers.
Triggering the Outbound Process via Stand-Alone Programs:
Stand-Alone programs are started explicitly by a user to transmit data from one SAP system to another. Standard Programs for several master data objects exist in SAP. Ex. The material master data can be transferred using the RBDSEMAT program or transaction BD10.
The stand-alone programs provide a selection screen to specify the objects to be transferred and the receiving system. After the stand-alone program is executed, it calls the IDoc selection program with the specified parameters.
Triggering the Outbound Process via Change Pointers:
The change pointer technique is used to initiate the outbound process automatically when master data is created or changed.
A standard program, RBDMIDOC, is scheduled to run on a periodic basis to evaluate the change pointers for a message type and start the ALE process for distributing the master data to the appropriate destination. The RBDMIDOC program reads the table TBDME to determine the IDoc selection program for a message type.
Processing in the Application Layer:
The customer distribution model is consulted to make sure that a receiver has been defined for the message to be transmitted. If not, processing ends. If at least one receiver exists, the IDoc selection program reads the master data object from the database and creates a master IDoc from it. The master IDoc is stored in memory. The program then calls the ALE service layer by using the function module MASTER_IDOC_DISTRIBUTE, passing the master IDoc and the receiver information.
Processing in the ALE Interface Layer:
Processing in the ALE Layer consists of the following steps:
Receiver Determination: The determination of the receiver is done through Customer Distribution Model.
IDoc Filtering: if an IDoc filter is specified in the distribution model for a receiver, values in the filter are compared against the values in the IDoc data records. If a data record does not meet the filter criteria, it is dropped.
Segment Filtering: For each sender and receiver combination, a set of segments that are not required can be filtered out.
Field conversion: Field values in data records are converted by using the conversion rules specified for the segment.
Version change for segments: Segments are version-controlled. A new version of a segment always contains fields from the preceding version and fields added for the new version. Release in IDoc type field of the partner profile to determine the version of the segment to be generated.
Version change for IDocs: IDocs are also version controlled. The version is determined from the Basic Type field of the partner profile.
Communication IDocs generated: The final IDoc generated for a receiver after all the conversions and filtering operations is the communication IDoc. One master IDoc can have multiple communication IDocs depending on the number of receivers identified and the filter operations performed. IDoc gets the status record with a status code of 01 (IDoc Created).
Syntax check performed: IDoc goes through a syntax check and data integrity validation. If errors found the IDoc get the status of 26 (error during syntax check of IDoc Outbound). If no errors found the IDoc gets the status 30 (IDoc ready for dispatch ALE Service).
IDoc dispatched to the communication Layer: In the ALE process, IDocs are dispatched using the asynchronous RFC method, which means that the sending system does not await for data to be received or processed on the destination system. After IDocs have been transferred to the communication layer, they get a status code 01 (Data Passed to Port OK).
Processing in the Communication Layer:
To dispatch an IDoc to a destination system, the system reads the port definition specified in the partner profile to determine the destination system, which is then used to read the RFC destination. The RFC destination contains communication settings to log o to the remote SAP system. The sending system calls the INBOUND_IDOC_PROCESS function module asynchronously on the destination system and passes the IDoc data via the memory buffers.
Inbound Process in IDocs:
An inbound process used IDoc structure, posting programs, filter objects, conversion rules, a partner profile, service programs, and configuration tables to post an application document from an IDoc.
Posting Program:
Posting programs, which are implemented as function modules, read data from an IDoc and create an application document from it. A posting program exists for each message. Each posting program is assigned a process code. A process code can point to a function module or a work flow. In the standard program process codes always point to a function module.
Ex. The posting program for message type MATMAS is IDOC_INPUT_MATMAS which has a process code MATM.
Workflow:
A workflow represents a sequence of customized steps to be carried out for a process. The workflow management system is used to model the sequence, identify information required to carry out the steps and identify the person responsible for the dialog steps.
Partner Profile;
A partner profile specifies the components used in an inbound process (partner number, message type, and process code), the mode in which IDocs are processed (batch versus immediate), and the person to be notified in case of errors.
Process flow for the Inbound process via a Function Module:
In this process, IDocs are received from another system and passed to the posting function module directly.
1. Processing in the communication Layer:
The IDOC_INBOUND_ASYCHRONOUS program, triggered as a result of an RFC from the sending system, acts as the entry point for all inbound ALE processes. The IDoc to be processed is passed as an input parameter. Control is transferred to the ALE/EDI layer.
2. Processing in the ALE/EDI Interface Layer:
Basic integrity check: A basic integrity check is performed on the control record.
Segment Filtering and conversion: Filtering out unwanted segments and carry out any required conversion of field values.
Creation of Application IDoc: The application IDoc is created and stored in the database and a syntax check is performed. If there are errors it gets status code of 60 (Error during Syntax check of IDoc Inbound). At this point a tangible IDoc, which can be monitored via one of the monitoring transactions, is created and the IDoc gets status code 50 (IDoc Added).
IDoc Marked ready for Dispatch: IDoc gets the status code 64 (IDoc ready to be passed to application).
IDoc is passed to the posting program: The partner profile table is read. If the value of the Processing field is set to Process Immediately, the IDoc is passed to the posting program immediately using the program RBDAPP01.
3. Processing in the Posting Module:
The process code in the partner profile points to a posting module for the specific message in the IDoc. The posting program implemented as a function module either calls a standard SAP transaction by using the Call Transaction command for posting the document or invokes a direct input function module.
The results of execution are passed back via the function modules output parameters. If the posting is successful IDoc gets the status code 53 (Application Document Posted) or it gets status code 51 (Error: Application
