Using Custom Datasource to load Cube

Hi Guys,
Ok the scenario, I have created a custom datasource that is pulling data from R/3.
The datasource is working correctly because the the number of records in R/3 matches those that are being pulled into my PSA table for my Datasource....so all thats good.
Ok the next step is where I am struggling.
I thought it may be a case of creating a new infocube and just adding new dimensions and include the fields of that are in the datasource into those dimensions but that doesnt work.
Is their some documentation to doing this correctly?
Should the fields I am using in the datasource be available as infoobjects?
Thanks

Hi,
In BI for standard data elements you will have a set of predefined infoobjects that are equivalent of R/3 data elements. These start from 0(Zero).....
So the first thing to do is to find as many IOs possible that are having same characteristics as your fields in R/3 datasource. Remember if you find one IO for each field that is enough.
Once you find standard IOs there might be a possiblity that some of the fields in R/3 are not having any equivalent IO in BW. For this you need to create custom ones.
After infoobjects are finalsed you can add them to your cube and create transformations.

How to make use of 3EC_CS_1R for remote cube.

hi all,
I have activated the 3EC_CS_1A for consolidation reports but would like to use 3EC_CS_1R DataSource for remote cube, we have not installed SEM-BCS on the BI system, when trying to use the 3EC_CS_1R on the BI system, it complaints the DataSource can only be used by SEM-BCS. what is the best way to utilise this DataSource?
do I need to install SEM-BCS in order to use this DataSource? Can I just install BCS component only?
I am slightly confused as where SEM-BCS should be installed, on BI or ECC system?
cheers.

Custom Datasource using View COVJ - R8359 Invalid extract structure

I'm trying to build a custom datasource so I can get at plan line item data with partner object (I've tried using 0CO_OM_CCA_1 but I dont get the partner object for plan data - no idea why). So I thought if I create a datasource using COVJ I can get it out. However when I try and save the custom datasource (created using RSO2) I get the error R8359 Invalid extract structure: You tried to generate an extract structure with the template structure COVJ. This operation failed, because the template structure quantity fields or currency fields, for example, field WOG001 refer to a different table.
I saw posts saying when people get this error thye should reference the table these fields come from in the view. So I've talked to our ABAP'er and I asked him to reference the table these fields come from but he said this cant be done because these come from a structure not a table.
Any ideas?
Thanks
Joel

The WOG* columns in table COEJ, one of the tables contributing to the COVJ view, use CCCUR-CURKY as the reference table-column for those quantities. The ABAPer you spoke to is correct that CCCUR is a structure. View value fields inherit their reference table-column from the source, in this case COEJ, and since this source table is an SAP delivered table it cannot be modified change this reference.
This means that you're only option for extracting the data out of the COVJ view would be to create a Function Module and use that Function Module as the basis for your DataSource.

Issue with calling url using custom uri from page loaded in stagewebview

I am using stageWebView for showing webpage in my mobile app but don't know how to move back to my app once it gets loaded. In application descriptor file, I had already registered custom uri scheme (myapp://) for IOS devices and from the loaded page inside stageWebView, I was trying to call following URL myapp://webcam. But nothing had happened. It neither called LOCATION_CHANGE event of StageWebView not called INVOKE_EVENT of nativeapplication.
How can I fix this issue?
Thanks in advance,
Mamta

Hi Ashutosh,
yea it gets launched correctly from safari. But my problem is with the link(which is using custom uri scheme e.g myapp://backtoapp) in the loaded page inside StageWebView. It is not allowing app to moveback to app from StageWebView. Moreover these two event listeners INVOKE_EVENT(native application) and LOCATION_CHANGE(stagewebview) are not responding. Dont know what should I do in order to move back to app area(mainView.mxml) from StageWebView(native browser).
Thanks,
Mamta

Detecting when exception was thrown using custom class loader

Hello all,
I would like to implement the solution described here - http://stackoverflow.com/questions/75218/how-can-i-detect-when-an-exceptions-been-thrown-globally-in-java - that uses custom class loader in order to detect when an Exeption thrown somewhere in the JVM hosting my app, please note that exceptions might be thrown from 3rd party jars the app is using. So, thanks to help I got from another post, I've managed to code the custom class loader. My question is how can the class loader wrap the original exception, as the methods in ClassLoader deals with classes, not instances. So where should I set the original exception?
Thanks!

I think I'm missing something fundumental, forgive me for being slow...
This is what I did so far. For the exception wrapper I made a simple class extens Exception that recieve Exception in its ctor and store it. I also subclassed ClassLoader and override its loadClass(). I've registered it as the system classloader. My thinking was to check in that point that if the requested class is instance of Exception and if yes, returning my wrapper class wrapping this exception. But, since loadClass() return class, how can I set in the wrapper the original exception?
In addition, let's say 2 different places in the code throws NPE, to my understanding the classloader will load NPE only once, so how throwing the NPE in the second time can be detected?you are missing a key point. you should creating a custom implementation of the NPE class which hooks into your detection code in its constructor. from that point forward, anytime any NPE (which is your custom class) is constructed, you can detect it.

How to load an applet using custom classloader ?

Hi All,
How to load an applet using custom classloader rather than using default browsers classloader i.e AppletClassLoader usually ?
Regards,
Kumar.

I would guess that that would require two applets.
The first does nothing but create the custom class loader and then load the second applet.

Load Text and Attribute using same DataSource

Hi,
Is it possible to load text and attributes using same datasource? If yes than how can this be done?
Thank you,
CD

Yes you are right in that case it will be an attribute , and in the report show it as display attribute. If you want to apply the text at Infoobject level,
(1) In the change mode of Iinfoobject , check both with Master data and Text boxes , in the Master data /text tab
(2) Make Flexible or direct update
(3) Create 2 Infopackages one loading from ATTR data source and the other from TEXT data source respectively.
hope it helps,

Correct DataSource to load data into 0EMPLOYEE InfoProvider.

Hi Experts,
I am implementing BW (7.0) - HCM (ECC 6.0). We are implementing functional areas such as OM, PA, PY, Leave, Time, Work Pattern Management, EHS, LSO and Comeptencies. We are implementing using standard BCT (Business Content).
The most important InfoProvider I've noticed that would be used across almost all the functional areas is 0EMPLOYEE. Now I have noted that there are a couple of Standard DataSources that load data (mostly Full Updates) into 0EMPLOYEE as below:
      Techinca Name                  -         Description
1) 0EMPLOYEE_ATTR                 -            Employee
2) 0EMPLOYEE_0077_ATTR       -            Employee - additional person data
3) 0EMPLOYEE_0016_ATTR       -            Employee - contract elements
4) 0EMPLOYEE_0763_ATTR       -            Long-Term Incentives Participant Data
5) 0EMPLOYEE_ID_ATTR            -            Employee - personnel ID
6) 0EMPLOYEE_USER_ATTR      -            Employee - system user name
7) 0HR_PA_0                               -            Employee
8) 0EMPLOYEE_TEXT                  -            Employee (This is not a concern)
Points to be noted are:
1) All the DataSources have PERNR (Personnel Number) in common that maps into 0EMPLOYEE (Employee Number) in BW along with various fields which makes sense.
2) Most of the InfoPackages have Full Update.
My question is... which DataSources am I supposed to use to load 0EMPLOYEE? If all the DataSources, then in which sequence should I use the DataSources during Go-Live so that it is best suited for the project? Does this also mean that the PERNR field comes from only one table in ECC so that I don't have to bother about the Full Updates in various InfoPackages for different DataSources?
Also, are there any DataSources that I might have missed for 0EMPLOYEE?
Any help is much appreciated. Thanks in advance.
Regards,
Chandu

Hi,
Commonly I use 0employee_attr to get all data from HR infotypes, because when I want to add additionnal fields in 0employee_attr, I prefer focus on one datasource rather than managing several datasource.
But you can use any other datasources mentionned in your post to update data to 0employee infoobject.
In the HR BCT, 0employee is the main datasource that provide data from HR infotypes, but this datasource is only a full type.
You have 2 options :
1°) If your HCM manages alot of employee, you can face performance loading problems. So, most of the time people don't use 0employee_attr datasource, but create one customer datasource per infotype (delta enable via enddate). You will thus manage one DSO perdatasource to load the target infocube.
2°) If your HCM manages a range of employee which performance are OK, you can use 0employee_attr, and then use the standard BCT.
Load your data and check the performance.
The reason why performance of 0employee_attr is poor according to me is that the module function that extract data manage the "PROVIDE" function that align data from the several infotype according to begin and end date.
Form a BCT point of view you can use 0PAPA_C02 for headcount analysis and/or 0PA_C01 for heacount and action analysis. You can use these cubes and add addditionnal fields regarding to addintionnal information from your HR infotypes. In both cases, they build a historical view per month of employee situtation, that is very insteristing in HR reporting.
Feel free to ask questions.

Error while transporting custom datasource

Hi All,
Below is the scenario that was carried out in my project.
1. Created OHD to load data from a CUBE to Data base Table /BIC/ABC.
2. Created a custom Datasource ZABC_TEST with the above table.
3. Activated the DataSource and loaded the data. (Data load successfull. It works fine).
4. Tried transporting the above. But trows error while transporting the data source.
Error -- InfoSource ZABC_TEST is not available in source system BITST.
Let me know what can be done to solve the above error. Please suggest if i have missed out something.
Thanks in advance.
Maddy

HI,
The problem seems to be occuring since you are transporting both OHD and DS in the same TR request.
Transport first the DS in a request, then in another request transport the OHD.
This should resolve the issue.
hope this helps.
thanks,

Procedures for implementing a snapshot scenario with custom DataSources

Hi Gurus,
I have checked the How To paper ([How to Handle Inventory Management Scenarios in BW (NW2004)|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/f83be790-0201-0010-4fb0-98bd7c01e328]). However, only SAP standard BW objects are mentioned in the paper e.g. InfoCube (0IC_C03), Material Stock InfoSource (2LIS_03_BX), Material movements IS (2LIS_03_BF) and Revaluations IS (0LIS_03_UM).
On the contrary, I need to handle custom DataSources for the Snapshot scenario. Are there any differences in the implementation methodology? Which additional aspects should I take into consideration? For example, the load sequence, delta type, etc.
Could you please list out the step-by-step procedures for such an implementation?
Thanks in advance!
Regards,
Meng

Hi Meng,
You can approach this in two ways.
1) If the volume of data is not much, you can derive the balance at query level, as follows.
User enters the date, based on this restrict your key figure to display all values less than this date.
2) If the volume of data is high, then you will have issues with performance if you are calculating the balance in the front end. In this case, you can model this with 'Non cumulative' key figure. Again there are 2 ways of approaching this back end solution based on the volume of data. ( Say in one case you have 2 years of history in your DSO and in the second case, you have 5 years of history ).
A) For example, If there are only 2 years of history
Create a non cumulative Key figure 'ZBALANCE' with inflow and outflow, in a cube.
Map this to your credit and debit as + and - respectively and map the calender day to posting date.
Just initialise the dataload with data transfer and start loading the delta as normal.
You will be able to see the balances for each and every calday in your reporting.
This approach is straight forward and simple.
Compress the cube for getting the better performance.
B) If there are 5 years of history and you are not interested in loading all the 5 years data in getting the balance
Here you want to have the initial balance, continue delta and would like to load 2 years of history.
The cube and non cumulative KF are created as mentioned above.
For generating initial balance, you have to create another DSO without calander day and ZBalance mapped to credits and debits in additive mode. Load your DSO data into this new DSO to generate initial balance. This balance will be loaded to your cube as initial balance. ( Like 2LIS_03_BX ).
You have to compress this request with marker update ( Must ).
Load your historical data for 2 years from the original DSO. Compress without marker update ( Must ).
initialise without data transfer from DSO to cube and load deltas normally.
Compress the delta requests normally for performance reasons.
Please read the 'Inventory document' in detail.
Please let me know, if any of the information is still not clear.
Thanks,
Krishnan

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

Steps to Enhance Custom DataSource

Hello All,
I have one custom datasource ZZ_PROD. From which I am extracting data and populatd in a ODS and then in to Cube in BI 7.0
Now I have to enhance it and add about more 20 fields from two different ECC tables.
These two tables are custom tables for a particular departmens.
Can somebody explain me the steps how I can accomplish this?
Thanks in Advance
Kumar M.

I would recommend to change the function Module or the program it generates the ZZ_PROD.
First Add the fields to the extract Structure.
Unhide the newly added fields in the data source.
Write the logic to grab the data from the two tables and assign it to proper extract structure fields.
We normally enhance the datasource using User Exit since we don't want to make changes to SAP Delivered programs that would be overwritten during upgrades.
Hope that helps.
thanks.

Master Data Datasource Enhancement or Custom Datasource

HAI
Im implementing the BI7.0 for procurement. We need to the data for VENDOR from XK03(T-code).
In XK03 , we have some custom defined class and its charateristic values .
So if i want to use 0vendor then i need to enhance the standard datasource of 0VENDOR.
So cani enhance the standard datasource or can my abaper create a custome R/3 table and load the vendor details. Then i will create the custom datasource. And load the data into BW.
Pls tell me how to do this one.
kumar

hi,
why u want take abap helper, if u want u can create ur customet table ur self go to se 11 create table and enter field what u want , and define lenth and chat type. got o rsa5 create ur data soure and replicate in be side and upload into ur data targets
u need more than 1 table u can create view got to se11 create view.

Custom Datasource for infoobject

Hello Guru
i have created a custom datasource on a SAP table (custom table) to update data from SAP into an infoobject in BW. Everithing works correclty but when i delete an entry in the custom table and update this in BW the entry in the infoobject is not deleted.
The infopackage and DTP are FULL.
How can i fix this problem and have always SAP table alligned with master data in the infoobject (new entry and DELETE entry)?
thanks
Boris

As you have created the generic extractor ans alos you are running
the full load.
In case of standard extractor delta will be handeled by the
extractor itself ,but it is not the same with the custom one.
We face one scenerio with the generic extractor.
1.Customer used to craete the notification on some date.
2.The same notification was deleted on some other day.
3.As in bw t=we load the previos day data.
4.So we were facing the problem like notification in
the r/3 side was deleted but they were still there in the BI side.
What we did is there is one field ie deletion flag and it set to 'X'
whenever we delete any record by default it is blank.
So we included the deletion flag file din the extractor and
create the same in the BW side.
At lat we restricted the query by filter "blank'.
So it was not showing the deleted notification in the report.
Thanks,

Custom DataSource plays in JMStudio, but not in my application

hello everyone. I need someone to help me out who has played around a lot with DataSources.
I have been playing around with custom DataSources for a small while and I have not been able to figure out something and its starting to get frustrating.
First let me tell you what process I exactly follow when I want to create a Custom DataSource (using the "Generating Live Audio/Video Data" datasource code sample as an example - from JMF solutions http://java.sun.com/products/java-media/jmf/2.1.1/solutions/LiveData.html):
1. Suppose the source files (DataSource.java and LiveStream.java) are lying at C:\customds\.
I compile the files like this:
javac -d . DataSource.java LiveStream.java
As a result this directory is formed C:\customds\jmfsample\media\protocol\live which contains all the compiled (interpreted) files.
2. Then I register 'jmfsample' in the Protocol Prefix list and commit the changes using the JMFRegistry GUI.
3. Now if I run JMStudio and enter the URL live: it gives me an error that it can't create a player. I feel this is happening because some classpaths haven't been set correctly. Eventually I figured out that I have to place the \jmfsample\media\protocol\live\ directory inside the <JMF install dir>\lib\. Doing this fixes the problem and now I can go to JMStudio and run the protocol using the 'Open URL'. Giving it 'live://' plays the 'blue screen' like a gem.
4. But here is the catch now. When I create an application which tries to create a player using live:// as a source, it doesn't run and keeps giving me a noPlayerException, or a noDataSourceException (as the case would apply; code given below).
The funny part is that i checked the JMStudio source code for the method that is used to 'Open URL'. I haven't found any siginificant change in the way it opens urls.
I also went a step further and tried to compile and run the JMStudio code myself to trace the code when it is in the process of opening a url. The weird thing is that when I try to do that, giving live:// as a URL gives me the same error that is given by my application. In other words JMStudio when compiled by me gives me same the error of "can't create a player..." when I open the url live://. Has Sun used a JMStudio compiled using a different source file?
Please please anyone tell me what is wrong here.
I have basically tried out these two kinds of things in my code, and both give me a noPlayerException error:
Player guiPlayer = Manager.createRealizedPlayer(new MediaLocator("live://"));and
DataSource ds = Manager.createDataSource("live://");
Player guiPlayer = Manager.createRealizedPlayer(ds);Thanking in anticipation.
regards

Would it be possible for you to expand on your solution a little bit? I'm trying a similar approach, and having a similar problem to yours. From Googling, it appears as if this is a very common problem, and a lot of people give up before they solve it.
I'm trying to use jmf.jag (and optionally add fobs4jmf.jar), not compile it from source. But I am trying to compile my own protocol from source and run it in a debugger. I have all the class files going out to the same output directory, and IntelliJ generally adds them all to the CLASSPATH automatically. But I keep getting NoPlayerException. (If I break down the players construction step-by-step, it seems to fail on "Processor ps = Manager.createProcessor(ds);".)
I'm trying to play a Quicktime movie from memory, and I've confirmed that I'm returning "video.quicktime", that my stream is Seekable and isRandomAccess returns true, my prefix is in the protocol list, and that the package name is correct. I've tried with PLUGIN_PLAYER being true or false, media type being video.quicktime or unknown, and every other permutation I can think of.
Any help would be greatly appreciated.
