PU12 or Change Pointers - which is better

Hi all,
Our Req is to track the changes in the infotype records which are valid as of today. The Receiver system would hold only one record at any point of time and it is valid as of today. But the sender system (SAP) may have Future or Past dated records.
Our approach for this would be using PU12 or Change Pointers.
If anyone of you worked with Change Pointers and/or PU12 for building interfaces from SAP to external systems using XI (proxy class calls), pls respond with the following queries.
--> Which one of these is a better approach?
--> In case of Change Pointers, how have you tracked and exported future dated and active back dated changes to the external interface.
--> Did you face any limitations with PU12/ Change Pointers approach.
Any help regarding this would be of great help.
Regatds,
Teja.

I don't know what PU12 do, but change pointer used to distribute only Master data.. Change pointer only generate an Idoc only for the changed fields rather for all the fields in idoc type..

Change pointers in ALE/IDOCs

Hi guys,
Can any let me know step by procedure to implenent change pointers using IDocs including ALE settings as i am new to this concept.
Any step by step example will be helpful. useful answers will be rewarded.
Thanks in advance.
Regards,
vinay

Change pointers is the one of the IDOC processing method in ALE.
In this once we make the config to any of messages type , if any changes are made in sending system then IDOC will be posted directly to destination with user interation.
Changes pointers are configured using BD50,BD51,BD53,BD61.
Change pointers are stored in tables BDCP and BDCPS (or BDCP2 in case of high-performance setting) - like CDHDR and CDPOS for change documents (but this is not a controlling table!).
1. Do you really need change pointers?
You need change pointers to distribute changes with the ALE SMD tool. If you do not use this tool, you do not need to write change pointers.
You can deactivate change pointers and activate them again with the transaction BD61.
2. Do you really need to activate change pointers for this messages type?
If some messages types are no longer to be distributed by change pointers, you can
deactivate change pointers for this message type.
You can deactivate change pointers for the message type
and reactivate them again in transaction BD50.
For reduced message types, deactivate the change pointer with the
Reduction tool (transaction BD53).
Applications which write change documents will also try to write change pointers for ALE operations. These are log entries to remember all modified data records relevant for ALE.
Most applications write change documents. These are primarily log entries in the
tables CDHDR and CDPOS.
Change documents remember the modified fields made to the database by an
application. They also remember the user name and the time when the modification
took place.
The decision whether a field modification is relevant for a change document is
triggered by a flag of the modified fields data element. You can set the flag with
SE11 by modifying the data element.
For the purpose of distributing data via ALE to other systems, you may want to
choose other fields, which shall be regarded relevant for triggering a distribution.
Therefore R/3 introduced the concept of change pointers, which are nothing else
than a second log file specially designed for writing the change pointers which are
meant to trigger IDoc distribution via ALE.
So the change pointers will remember the key of the document every time when a
relevant field has changed.
Change pointers are then evaluated by an ABAP which calls the IDoc creation, for
every modified document found in the change pointers.
The Change pointers are written from the routine CHANGEDOCUMENT_CLOSE
when saving the generated change document. So change pointers are automatically
written when a relevant document changes.
The following function is called from within CHANGEDOCUMENT_CLOSE in order to write the change pointers.
CALL FUNCTION 'CHANGE_POINTERS_CREATE'
EXPORTING
change_document_header = cdhdr
TABLES
change_document_position = ins_cdpos.
Activation of change pointer update :
Change pointers are log entries to table BDCP which are written every time a transaction modifies certain fields. The change pointers are designed for ALE distribution and written by the function CHANGE_DOCUMENT_CLOSE.
Change pointers are written for use with ALE. There are ABAPs like RBDMIDOC
which can read the change pointers and trigger an IDoc for ALE distribution.
The change pointers are mainly the same as change documents. They however can
be set up differently, so fields which trigger change documents are not necessarily
the same that cause change pointers to be written.
In order to work with change pointers there are two steps to be performed
1) Turn on change pointer update generally
2) Decide which message types shall be included for change pointer update
R3 allows to activate or deactivate the change pointer update. For this purpose it
maintains a table TBDA1. The decision whether the change pointer update is active
is done with a Function Ale_Component_Check
This check does nothing else than to check, if this table has an entry or not. If there is an entry in TBDA1, the ALE change pointers are generally active. If this table is empty, change pointers are turned off for everybody and everything, regardless of the other settings.
The two points read like you had the choice between turning it on generally or
selectively. This is not the case: you always turn them on selectively. The switch to
turn on generally is meant to activate or deactivate the whole mechanism.
The change pointers which have not been processed yet, can be read with a function
module.
Call Function 'CHANGE_POINTERS_READ'
The ABAP RBDMIDOC will process all open change pointers and distribute the
matching IDocs.
When you want to send out an IDoc unconditionally every time a transaction
updates, you better use the workflow from the change documents.
To generate the IDOCS in case of change pointers we need to use the standard report
RBDMIDOC
we need execute the follwing t.code
BD61:to activate the change pointers globally
BD50,BD52: to activate message types ,and to enable the fileds for change pointers
Hope this link will help you regarding Change Pointer...

Change Pointer Configuration and extraction in HRPay.
Infotypes to be logged are in:
V_T585A,
V_T585B,
& V_T585C
Please view the table contents to understand the structure of these tables and how they are linked. These help you identify the cluster tables which store the data.
Payroll Cluster Table PCL4 contains the cluster table reference. (Please refer to the table structure below:
Payroll Custer Tables
http://www.planetsap.com/HR_ABAP_payroll.htm
Cluster tables combine the data from several tables with identical (or almost identical) keys into one physical record on the database.
Data is written to a database in compressed form.
Retrieval of data is very fast if the primary key is known.
Cluster tables are defined in the data dictionary as transparent tables.
External programs can NOT interpret the data in a cluster table.
Special language elements EXPORT TO DATABASE, IMPORT TO DATABASE and DELETE FROM DATABASE are used to process data in the cluster tables.
PCL1 - Database for HR work area; (long text, etc)
PCL2 - Accounting Results (time, travel expense and payroll); (payroll results)
PCL3 - Applicant tracking data;
PCL4 - Documents, Payroll year-end Tax data (change logs, etc)
Database Table PCL4
The database table PCL4 contains the following data areas:
LA change logs (long term documents)
SA Short-Term Documents for HR Master Data
SB Short-Term Documents for Applicant Master
SRTFD (PC400) = trans class always A for master data (1) pernr (8) info type (4) modified date (8) modified time (8) seqnr (4)
Please note that for the extraction of data, you have to use the date portion of the SRTFD and not the field value AEDTM(since it is not primary key).
Naming convention for INCLUDES when defining clusters. These INCLUDES will define the work area key above and the cluster data that is returned from an IMPORT:
RPCnxxy0
n = 1, 2, 3 or 4 (for PCL1, PCL2, PCL3, PCL4)
xx = cluster ID
y = country grouping (0 for international otherwise country indicator T500L)
Description of Cluster Data using Cluster RX as an Example
The data description is stored in the include RPC2RX00 in accordance with the above naming conventions.
RPC1TX00 - Long text cluster ID in table PCL1
RPC2RUU0 - Payroll results for the US cluster ID in table PCL2
RPC4LA00 - Change log cluster ID in table PCL4
Importing Data (I)
The IMPORT command causes data objects with the specified key values to be read from PCLn.
If the import is successful, SY-SUBRC is 0; if not, it is 4.
REPORT ZRPIMPORT.
TABLES: PCLn.
INCLUDE RPCnxxy0. "Cluster definition
Fill cluster Key
Import record
IMPORT TABLE1 FROM DATABASE PCLn(xx) ID xx-KEY.
IF SY-SUBRC EQ 0.
Display data object
ENDIF.
See sample program for long text.
Importing data (II)
Import data using macro RP-IMP-Cn-xy.
Check return code SY-SUBRC. If 0, it is successful. If 4, error.
Need include buffer management routines RPPPXM00
REPORT ZRPIMPORT.
*Buffer definition
INCLUDE RPPPXD00.
DATA: BEGIN OF COMMON PART 'BUFFER'.
INCLUDE RPPPXD10.
DATA: END OF COMMON PART 'BUFFER'.
*import data to buffer
RP-IMP-Cn-xy.
*Buffer management routines
INCLUDE RPPPXM00.
Cluster Authorization
Simple EXPORT/IMPORT statement does not check for cluster authorization.
Use EXPORT/IMPORT via buffer, the buffer management routines check for cluster authorization.
rpcbdt00 - include needed for importing from database PCL4(la) (Change log cluster ID)
Please note that data for change pointers is stored at two levels: 1) Header which has the key info and 2) BELEGE which has the changed info ie. Old value and new value.
Check standard program RPUAUD00

hi,
Applications which write change documents will also try to write change pointers for ALE operations. These are log entries to remember all modified data records relevant for ALE.
Most applications write change documents. These are primarily log entries in the
tables CDHDR and CDPOS.
Change documents remember the modified fields made to the database by an
application. They also remember the user name and the time when the modification
took place.
The decision whether a field modification is relevant for a change document is
triggered by a flag of the modified field’s data element. You can set the flag with
SE11 by modifying the data element.
For the purpose of distributing data via ALE to other systems, you may want to
choose other fields, which shall be regarded relevant for triggering a distribution.
Therefore R/3 introduced the concept of change pointers, which are nothing else
than a second log file specially designed for writing the change pointers which are
meant to trigger IDoc distribution via ALE.
So the change pointers will remember the key of the document every time when a
relevant field has changed.
Change pointers are then evaluated by an ABAP which calls the IDoc creation, for
every modified document found in the change pointers.
The Change pointers are written from the routine CHANGEDOCUMENT_CLOSE
when saving the generated change document. So change pointers are automatically
written when a relevant document changes.
The following function is called from within CHANGEDOCUMENT_CLOSE in order to write the change pointers.
CALL FUNCTION 'CHANGE_POINTERS_CREATE'
EXPORTING
change_document_header = cdhdr
TABLES
change_document_position = ins_cdpos.
Activation of change pointer update :
Change pointers are log entries to table BDCP which are written every time a transaction modifies certain fields. The change pointers are designed for ALE distribution and written by the function CHANGE_DOCUMENT_CLOSE.
Change pointers are written for use with ALE. There are ABAPs like RBDMIDOC
which can read the change pointers and trigger an IDoc for ALE distribution.
The change pointers are mainly the same as change documents. They however can
be set up differently, so fields which trigger change documents are not necessarily
the same that cause change pointers to be written.
In order to work with change pointers there are two steps to be performed
1) Turn on change pointer update generally
2) Decide which message types shall be included for change pointer update
R3 allows to activate or deactivate the change pointer update. For this purpose it
maintains a table TBDA1. The decision whether the change pointer update is active
is done with a Function Ale_Component_Check
This check does nothing else than to check, if this table has an entry or not. If there is an entry in TBDA1, the ALE change pointers are generally active. If this table is empty, change pointers are turned off for everybody and everything, regardless of the other settings.
The two points read like you had the choice between turning it on generally or
selectively. This is not the case: you always turn them on selectively. The switch to
turn on generally is meant to activate or deactivate the whole mechanism.
The change pointers which have not been processed yet, can be read with a function
module.
Call Function 'CHANGE_POINTERS_READ'
The ABAP RBDMIDOC will process all open change pointers and distribute the
matching IDocs.
When you want to send out an IDoc unconditionally every time a transaction
updates, you better use the workflow from the change documents.

Which change pointers should I activate for PDS'

Hi Gurus,
I have a scenario where I am creating PDS' from only BOMs in ECC. I have set up integration models for all the necessary BOMs. The Initial transfer worked seamlessly. I have made a few changes to BOMs in ECC and I noticed that the change flag in CURTO_PDS_CHG table is not being set. But when I create new BOMs, the change flag in CURTO_PDS_CHG is being set. As a result, I am not able to do a change transfer for PDS.
I believe this is happening because I have not activated the relevant change pointers for PDS. And I can not find relevant change pointers for PDS that I need to activate. Is any standard message type that I can activate (in transaction BD50) for ensuring change transfer for PDS takes place?
The only change pointer( or message type) that looks relevant to PDS change transfer is -
1) CIFRTO_INFREC - APO-CIF: Change Production Data Structure Extl. Processing
But this message type does not have any tables/fields assigned in transaction BD52. If I have to use this message type for capturing changes to PDS', Do I have to maintain all the tables/field names for this message type? Isn't there any standard Message type that I can use?
Thanks in advance for your responses.

Hi. Will,
Thanks for the response. I have active integration models for Plant, Material and BOMs. I do not need routing or recipe or even production version in APO as I am transferring the BOMs to APO for a DP-BOM planning area.
And I am afraid the ECC system does not create relevant change pointers (relevant to CIF change transfer) when BOMs change. I think the table CURTO_PDS_CHG needs to be updated when a change takes place, for CIF to identify changes to BOMs and transfer them. Currently, ECC only updates the CURTO_PDS_CHG table when I add a new BOM to the integration model.
I did try to activate the message type CIFRTO_INFREC by adding various field form MAST, STPO etc in transaction BD52. But CURTO_PDS_CHG is still not updated when a change takes place in a BOM and hence the change is not transferred to APO. Is there anything that I am missing here?? Any help is appreciated.

Change Pointers - adding a new field to existing Change Document

Hi,
We have a requirement to capture the changes made to the Material object through the transaction C223. The changes to field MKAL-PRFG_F have to be captured.
There is an exisitng Change Document Object - MATERIAL. This is included in Message Type MATMAS. These are the steps we have done:
1. In SCDO - added the Z structure to the Change Document Object - Material. [Z structure contains the field MKAL-PRFG_F. Change pointer option is checked for this Data element.
2. Created a Z Message Type with reference as MATMAS.
3. In BD52 - we have listed the fields for the new Z Message Type created.
4. The Change Pointers - reactivated after the steps are done.
The changes to the field MKAL-PRFG_F through C223 Tcode are not recorded in BDCPV table.
Have we missed any steps here?
Thanks,
Pallavi

HI,
I don't think a new zmessage type is required in this case.. is the structure added to MARA table??The change document programs are there which triggers the iodcs... In SCDO transaction code , click on generation info for MATERIAL.. You will find the includes. The FM MATERIAL_WRITE_DOCUMENT creates entries in CDHDR and CDPOS, if we maintain entries in BD52 , the entries wil be written in BDCP and BDCPS tables.
Try to add your structure in MARA table as append strucre and then you can debug the IDOC from WE19 and use the FM "MASTERIDOC_CREATE_SMD_MATMAS" and then you also need to switch on Update Debugging on, to debug the changes in update FM MATERIAL_WRITE_DOCUMENT.
Please see if the change is reflected or not....
ELSE.
may be you need to create a new entry in SCDO and do all the ALE configurations for change pointers.
Please find the link for change pointers and also you can get lot of information on change pointers in SCN.

Change Pointers not being created for HR-PA Custom Infotype

Problem Description:
We have a custom Infotype in SAP to store the data for contingent employee - Infotype 9001. Change pointers is
turned on. We are running the program RBDMIDOC to send changes to Oracle IDM using message HRMD_A. The change
detected for all infotypes except 9001. For 9001, the change pointer is not created.
The following are the current configuration details:
IDOC Extension Created to Idoc type HRMD_A07 (ZHR_EXT)
custom segment zhr_seg
Change pointers are switched on.
Change pointers switched on for message Type HRMD_A.
IDOC configuration created for Port / Process code etc.
Maintenance of view T777D - Added ZHR_SEG.
If I add the segment ZHR_SEG as a 2nd segment to Infotype 0000, I dont get a syntax error. But the changes for Infotype 9001 are not picked up.
If I add the segment ZHR_SEG as a segment to Infotype 9001, I get a syntax error - check EDI: Syntax error in IDoc (mandatory segment missing) below.
EDI: Syntax error in IDoc (mandatory segment missing)
Message no. E0072
Diagnosis
The segment ZHR9001 has the attribute 'Mandatory' in the syntax description of the basic type HRMD_A07 (customer enhancement ZHR_EXT). However, the segment is missing in the IDoc. The segment number logged in the status record identifies the item before which the segment is missing.
This error may have been triggered by an unidentifiable segment before the expected mandatory segment.
Procedure
Please check the IDoc or the syntax description of the basic type HRMD_A07 (customer enhancement ZHR_EXT).

Were you able to resolve the issue?
If yes, could you please share what was done to resolve it.
Your help will be greatly appreciated.

Creation of Idocs from the change pointers by the program RBDMIDOC

Hello,
I'm Creating Idocs from the change pointers by the program RBDMIDOC.
The IDOCS Created using the message type HRMD_A are Correct but when i try to RUN RBDMIDOC for message type HRMD_B no Data is selected for distribution.
All the customizing are similar and i presume that all the change pointers are active (BD50 and IMG->Personnel Management -> Organizational Management -> Basic Settings -> Activate change documents).
Can anyone help me with the necessary steps to create this IDOC types.
Do anyone know if the RBDMIDOC report is the Same for messages HRMD_A and HRMD_B.
Thanks in Advance,
Pedro Ferreira

If the setting is fine, there may be some code in exit or badi for program RBMIDOC. Check the Exit and BADI.
check the exit EXIT_SAPLBD11_001 and
check the badi IDOC_CREATION_CHECK.
Probably there may be some code on these exits which are stoping your code from getting generated.These are the two trigger happen once u execute the RBMIDOC program.for HR, we use RHALEINI program to generate the idoc. but even RBDMIDOC works. These 2 triggere will come with RHALEINI also.
If there is no code here, Then there is problem in the setting only.

Need help On Triggers/Change pointers in SAP

Hi Experts,
I Need help On Triggers/Change pointers in SAP.
I have a requirement as soon as an entry is created in one of the Standard SAP table it should check against my Ztable and update and create the corresponding entry in another Ztable.
Can some one help me out on this with the syntax and how to do it

Hi,
Check whether you have any enhancement option (BADI, user exit, Customer enhancement etc) in the program which is used to save the data in the SAP standard table. If so, then try to write your code in that appropriate enhancement.

Which is better - Add a dimension or create more members in an existing

Which is better - Add a dimension or create more members in an existing dimension?
We are trying to figure out which can give us better performance in terms of calculations and retrieving reports - to add another dimension (entity/country) or add about 500-800 more members in an existing location/division dimension?
Thank you!

If you have BSO cube i would recommend to add in the same dimension where as ASO you can add members in a new dimension. Adding a new dimension is like creating a new cube you have to change each and every single calc scripts,report scripts,FR reports,Webforms and your rule files .... all the dependencies has to be changed manually . I think 500 members in the exsting BSO dimension will not impact the calc or retrieval times that much .

Which is Better? Mac or PC?

Which is Better?
Intel iMac Mac OS X (10.4.5)

Hello,
I'm not going to argue that a Mac is better, but I do have a response to:
looking computers and the software is great however
they have major compatibility issues. for example
many websites do not support mac's Ex.
www.aircanada.com
I have never had any problem exchanging documents or viewing web pages with the Mac.
All my document exchanges have worked flawlessly, and work going both to and from Windows PC's.
But, you need to make sure you are using the right program on the Mac if you want to share files with PC users.
As for the website compatibility, the site you provided as an example will work just fine. They just don't want you to know it.
What that website is doing, is running a check to see what web-browser you are using. Beyond that, they are also running a check to see which computer you are using.
So, what you need to do is make sure that your browser tells their website what it wants to hear.
So, in Safari, you can use the "Debug" menu to have Safari report itself as the Windows version of Internet Explorer.
Go to the Debug menu, then pick "User Agent", then choose: "Windows MSIE 6.0".
If the site still won't load, then go to the site first, and perform the selection again from the Debug menu.
Basically, what you are doing is changing what Safari identifies itself as.
Additionally, the website that you listed does list that it is compatible with Mac OS 9.0 or later. So, it should work provided you pass it's checks.
If for some reason it still won't work, contact them since they say that it is compatible with the Mac.
The only sites that absolutely will not work with a Mac are sites that use "Active X" to take over control of your computer or communicate directly with the operating system. Fortunately, those sites are getting rarer and rarer.
The only site I've run across in recent times that uses Active X is Microsoft's Windows Update site (which you wouldn't need with a Mac anyway).
As for enabling the "Debug" menu in Safari, if it is not already there, you can do that by:
Closing Safari
Open "Terminal" which is located at:
Hard Drive --> Applications --> Utilities --> Terminal
Then type the following at the command line:
defaults write com.apple.Safari IncludeDebugMenu 1
If you would prefer an automated method of enabling the Debug menu, you can always download the free Safari Enhancer program which includes a setting for this feature:
