Delta Upload for Customized DataSource

Hello,
I created a Customized DataSource with Full Upload and replicated DS in BW ,now i want to creat Dalta Upload for the same Data Source is it possible can i do ,is there any method or settings to be done to get Delta upload update..
I hope my thread is understandable....
ifnot get back ....!
Thanks

Hi Bhanu,
What is the Safety Upper & Lower limits you have given for your Generic Delta(RSO2 trans). That also matters.
Give Safety Upper limit as 0 & Lower Limit as 1, Replicate the DS once in BW & then try to load Delta.
If possible Delete the Init--> Load the Init again & then try loading Delta after changing the Safety limits & loading INIT.
Hope it helps you!

Pavan

Enable RDA for customized datasource

Hi
Please let me know step by step process how to enable RDA for customized datasource ( generic extraction by FM)
and how tio enable for standard datasource

Please let me know step by step process how to enable RDA for customized datasource ( generic extraction by FM)
Re: Real-Time Data Acquisition
and how to enable for standard datasource
goto se38 in ECC, and cerate an executable program with the following code
Tables : ROOSOURCE.
UPDATE ROOSOURCE set REALTIME = 'X'
WHERE OLPTSOURCE = "datasource name" and OBJVERS = 'A'.
when i am creating infopckage check box is disable for real time data?
U have to create TWO infopackages, one for Initialize Delta Process, and other for Real Time load...
Tricky thing here is, before creating Real_Time infopackage, u should load data through first infopackage (Initialize Delta Process).... Then only real time check box is enabled

Delta Upload for Flat File

Hello Everyone

Hi Sabrina...thank you for ur help...i did load the data from cube to ods
steps.
1. i generated export data source on the cube
2. i found the name of the cube with prefix 8<infocube name> in the infosource under DM application component.
3. there are already communication structure and transfer rules activated but when i am creating update rules for the ods..i am getting the message 0recordmode missing in the infosource.
4. so i went to infosource and added 0recordmode in communication structure and activated but the transfer rules in yellow colour..there was no object assigned to 0recordmode but still i activated.
5.again i went to ods and created update rules and activated (tis time i didnt get any message about 0recordmode).
6.i created infopackage and loaded.
a)Now my question is without green signal in the transfer rule how data populated into the ods and in your answer you mentioned to create communication structure and transfer rules where in i didnt do anything.
b) will i b facing any problem if i keep loading the data into the ods from cube (in yellow signal) ..is it a correct procedure..plz correct me..thanks in advance

Delta Field for CRM Datasources

Dear All,
I am using the CRM datasources such as

RSA7 shows zero records for delta upload of 2LIS_03_BF Datasource

Dear Professionals,
I am having constant issues with inventory management DataSource (2LIS_03_BF). I scheduled delta upload in r3 production using LBWE, keeping in mind that in LBWE there is no options for posting dates, ETC... In RSA3, there are records, but when i check RSA7, it is showing 0 records. What could be the problem. Do i need to do anything/activation anywhere in LBWE or RSA7 to see the records. Please advise.

Hi,
Normally there should be a collective run which transfers data from the application-specific queues to the BW delta queue (RSA7), just like this workflow:
MCEX03 queue==> RMBWV03 (Collective run job) ==> RSA7-Delta queue => BW
It is necessary to schedule the job control regularly - see point 3 of SAP Note 505700.
Check also these SAP Notes:
869628     Constant WAITUPDA in SMQ1 and performance optimization
728687     Delta queued: No data in RSA7
527481     tRFC or qRFC calls are not processed

Delta upload for generic data sources.

Hai All,
I tried as per SAP online document , but still i am not getting the result i.e delta upload from the BW side. Here i explained everything what i did.
In R/3
1. I have created a table with 3 fields SNO, SNAME, DOB
2. Then i created some entries in that table.
3. With Tr Code RSO2 i created one data source. Here i took Master Attribute Datasource
4. In generic delta i took the Generic field as DOB. and Time stamp and upper limit 10 sec.
In BW side
1. I have replicated the data sources under application compone in which i have creatred in R/3..
2. Then i activated that data source and created infopackage for that.
3. in the selection i have specified 01.01.1900 to 01.01.9999
4. First i made Full Update then i get all the records from R/3.
5. In R/3 i have created 2 more entries.
6. In Infopackage UPDATE Tab i have selected the Initilize Delta Process ( Initialization with Data Transfer).
For this i am getting the error message as follows.
Error message from the source system
Diagnosis
An error occurred in the source system.
System Response
Caller 09 contains an error message.
Further analysis:
The error occurred in Extractor .
Refer to the error message.
Procedure
How you remove the error depends on the error message.
Note
If the source system is a Client Workstation, then it is possible that the file that you wanted to load was being edited at the time of the data request. Make sure that the file is in the specified directory, that it is not being processed at the moment, and restart the request.
Here i closed the all things in R/3 as per the note mentioned above. Still it is giving the error message.
If i select the Intilization Delta Process( Intilization with out Data Transfer) then i am getting the option Delta Update . I selected this Delta update and scheduled but no data is coming.
Please help.
Regards
Prashanth K

Hai Sachin,
I am getting the problem at PSA only. Actually that is connected to ODS Object only. Until unless we don't get the delta data into PSA we can't proceed futher. So please help. I am working on NW 2004S.

Delta upload for flat file extraction

Hello everyone,
Is it possible to initialize delta update for a flat file extraction, If yes please explain how to do that??

Hi Norton,
For a Flat file data source, the upload will be always FULL.
Please refer to following doc:
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a0b3f0e2-832d-2c10-1ca9-d909ca40b54e?QuickLink=index&overridelayout=true&43581033152710 if you need to to extract delta records from Flat file. We can write routine at infopackage level.

Player for custom datasource

Hi
I need to create a custom datasource but i want to play it on a player as other normal datasource.
I tell you what im doing, I have developed a example to show you my problem:
first thing i do is creating a custom datasource:
import javax.media.*;
import javax.media.protocol.DataSource;
import javax.media.protocol.ContentDescriptor;
public class myCustomDataSource extends DataSource {
     myCustomDataSource(MediaLocator ml){}
     public void connect(){}
     public void disconnect(){}
     public void start(){}
     public void stop(){}
     public String getContentType() {
          return ContentDescriptor.CONTENT_UNKNOWN;
     public Object[] getControls() {
         return new Object[0];
     public Object getControl(String type) {
         return null;
     public Time getDuration(){
          return Time.TIME_UNKNOWN;
}then, I create a basic class that use a player for playing my custom datasource:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.media.*;
import javax.media.protocol.DataSource;
public class VideoPlayer extends JFrame {
     Player player = null;
     private JPanel contentPane;
     public static void main(String args[]){
          String mediaFile = "http://noodle.med.yale.edu/demos/dsr_arrow.mpg";
          MediaLocator locator = new MediaLocator(mediaFile);
          myCustomDataSource mcds = new myCustomDataSource(locator);
          (new VideoPlayer(mcds)).setVisible(true);
     public VideoPlayer(myCustomDataSource ds) {
          super("Example");
          setSize(400,400);
          contentPane = (JPanel) this.getContentPane();
          addWindowListener(new myWindowAdapter());
          try {
               player = Manager.createPlayer(ds);
               player.addControllerListener(new controllerUpdate());
          }catch(Exception e){
               System.err.println("Error loading the media. ("+e+")");
          if(player!=null) player.realize();
     class controllerUpdate implements ControllerListener {
          public synchronized void controllerUpdate(ControllerEvent e) {
               if(e instanceof RealizeCompleteEvent) {
                    Component visualArea = player.getVisualComponent();
                    Component controlPanel = player.getControlPanelComponent();
                    if(visualArea!= null)
                         contentPane.add(visualArea, BorderLayout.CENTER);
                    if(controlPanel != null)
                         contentPane.add(controlPanel, BorderLayout.SOUTH);
                    validate();
                    player.prefetch();
               if(e instanceof PrefetchCompleteEvent) {
                    player.start();
     class myWindowAdapter extends WindowAdapter {
          public void windowClosing(WindowEvent e){
               if(player!=null) player.close();
                    System.exit(0);
}when i run it i get the next error: Error loading the media. (javax.media.NoPlayerException: Cannot find a Player for: myCustomDataSource@be0e27)
I dont know how i must fill the myCustomDataSource class constructor and abstract methods to run it.
I test videoplayer class with a normal datasource and it works
sorry for my bad english
Thanks so much

ok, thanks for answering,
I see a sun webpage example maybe can help: http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/solutions/JpegImagesToMovie.html
In that example, a custom datasource is declared and then a processor is created with that custom datasource using Manager.createProcessor. For that, custom data source class is declared inside class where processor is used. Im trying to do it but it doesnt work, i get the same error.
thanks in advance

Delta Replication for Customizing object from ECC- CRM

I need help on delta replication activate for customizing objects from ECC to CRM. I finished with initial load with product replication and everything worked weel. The problem is that product hierarchy continuely changing in ECC everyday, so the delta for the products error out due to incorrect product heirarchy in CRM becuase the delta is not working for DNL_CUST_PROD0, and DNL_CUST_PROD1. Please show me how to activate the delta for those DNL. What business transaction do I need for those so the delta will work for them too? Rewards points if helpful

I think you need to do Request downlaod for the Product Hirearchy when ever there is new one created in ECC.You can do request downlaod by creating the object using R3AR2. Exeute the object though R3AR4 and monitor the status using R3AR3.

Delta upload for DB connect.

hi all,
i have a small querry- i have to load data in a cube every month. my data source is a SQL table.
i will load data using DBCONNECT.
do we have delta update option for DBCONNECT, because in my info package i can see only "Full upload" option.
if delta upload is available, then how do i get this option in info package.
thanks a lot.
Regards,
Shruti

Hi Shruti,
In infopackage, in the tab for data selection, we can see some fields for selection. On those fields - we can write an abap code (routine) which will have some logic to find the last update date and then populate the selection field based upon this last update date + 1. So the info package will dynamically fetch the required records.

Amit Mittal.

Delta upload for total fisl extractor

Hello,
Its said that the BALANCE field in the transfer structure is not supplied with data during Delta upload .
Would you know the reason for this?
I assume this is for the totals extractor only since balance is not available otherwise.
Regards
Pascal

Because the change record updates the movements not the balance
And you can back post - ie post to a period already gone - so if yuu wanted balance to be provided you would then have to change every periods balance b/f in the extractor from the backposted period onwards
Easiest way to do it - do it in the cube (as per the OSS note) and let compression deal with getting rid of the extra records created

Delta setup for 2lis_03_bx datasource very urjent

Hi All,
I am using Inventry Cube 0IC_C03 i am loading the data from R/3 data source 2LIS_03_BX. i have loaded 55 records first time , now i want do the delta loads , but in LBWE not able to find out this datasource so please can u anyone help me how we will do delta loads for this 2LIS_03_BX DSource , where we i will setup for the delta .please anyone give me the detail steps
thanks
KK

Hi KK,
For 2LIS_03_BX data source you cannot load DELTA because it is only for stock initialization. That is why you cannot find this in LBWE.
Once you load this INIT stocks in BW you can have delta for 2LIS_03_BF and 2LIS_03_UM in LBWE.
Hope this helps.
Assign points if useful.

Delta issue for Customized field in LO Datasource.

Hello,
I have one customized field 'ZCOORNAME' in the DS 2LIS_05_Q0NOTIF. I have changed this field in Tcode- QM02 and checked the changes in TCODE - LBWQ (Extraction Queue) and I got the Changed entry but now when i am trigerring the V3 Job, these changes are not getting populated in RSA7 (Delta Queue).
For standard field changes, it is capturing delta properly, the problem is with only customized fileds..Can anyone put some light on this issue ....
Can you pls le me know when will be the Customer Exit(CMOD) is going to hit ? Before the Delta Queue or After the Delta Queue or is it before the Extraction Queue / After the Extraction Queue ???

Please try activating the datasopurce again and try it.
Can you pls le me know when will be the Customer Exit(CMOD) is going to hit ? Before the Delta Queue or After the Delta Queue or is it before the Extraction Queue / After the Extraction Queue ???
he customer exit is hit before the entries are populated in extraction queue. Actually, when the transaction is done, the changes are written to database table and at the same time into the extraction queue. Just before going to extraction queue, the custom fields get populated in customer exit.

Delta update for 0FI_AR_4 DataSource

Hi Experts,
We have a couple of reports (Infoprovider ODS) which are based on the 0FI_AR_4 DataSource. We have enhanced the Datasource and added 7 to 8 fields from SD and FI region. For enabling delta current mapping is: UPDMOD (R/3) field mapped to 0RECORDMODE (BW).
One of the enhanced FI field is Collection Specialist. If this Collection Specialist Master record is changed for a particular Customer, all the newly generated Accounting Document shows the current Collection specialist but the already existing Accounting Document in BW are not getting converted to the current Collection Specialist.
Enhancement Code for 2 fields:
1. SELECT SINGLE KLIMK FROM KNKK INTO V_KLIMK
         WHERE KUNNR = l_s_dtfiar_3-KUNNR AND KKBER = l_s_dtfiar_3-KKBER.
     IF SY-SUBRC = 0.
         l_s_dtfiar_3-ZZKLIMK = V_KLIMK.
     ENDIF.
2. CLEAR: WA_UDMBPSEGMENTS.
    SELECT * FROM UDMBPSEGMENTS INTO WA_UDMBPSEGMENTS
                               WHERE PARTNER = l_s_dtfiar_3-KUNNR.
    ENDSELECT.
    IF SY-SUBRC = 0.
        SELECT * FROM UDM_SGMT_COMP INTO TABLE IT_COMP_CODE
                               WHERE COLL_SEGMENT = WA_UDMBPSEGMENTS-COLL_SEGMENT.
        LOOP AT IT_COMP_CODE.
          IF IT_COMP_CODE-COMP_CODE = l_s_dtfiar_3-BUKRS.
            l_s_dtfiar_3-ZZCOLL_SPECL = WA_UDMBPSEGMENTS-COLL_SPECIALIST.
          ENDIF.
        ENDLOOP.
     ENDIF.
     CLEAR   : IT_COMP_CODE
Please suggest what can be done to resolve the issue.
Thanks,
Vivek

Hi,
I hope you have written the codes in R/3 side.And whenever the Collection Specialist Master record is changed for a particular Customer, all the newly generated Accounting Document show the current Collection specialist but the already existing Accounting Document in BW will not converted to the current Collection Specialist since the data in BW is old data and no logic is written to convert the same.
Try to incorporate the logic to convert in BW also.
I could suggest is whenever there is change in Collection Specialist Master record , try to trigger a delat record generation that updates the old accounting doc withnew master in the delta load.

Problem in delta management for custom fields added in standard Table

Hi developers,
we have a problem, when a sales order is modified in a field custom, added in tables (VBAP-VBAK), the delta BW doesn't recognize the modifications. The data type of these fields haven't the flag (Change document) setted in
view Definition.
If this flag is setted, Can the delta BW recognize the modifications of the custom fields?
Best regards
Domenico

You cannot get delta by just appending fields to extract structure & writing the user exit coding as this user exit code is run by the extractor after the X- and Y- tables are compared to create the before & after images.
You have to do this procedure by enhancing LIS comm structures like MCVBAP (for example).
Please refer to OSS note 576886 for complete details.
