Creating a custom datasource

hai all,
I saw one example in jmf website "LiveStream", in which we can play the video with RGP format(custom data). They will create the video data in RGP format and we can create the test pattern. have any body tried that, if you are able to do that, kindky let me know that.
Thanking you all
antony

I didn't try this, but have you taken a look at JMF Solutions page ?
I saw there something about creating a custom datasource:

Creating a custom datasource. Please help!

Hi Experts,
I'm creating a custom datasource in RSO2 to extract data from a custom view based on three z tables. I have filled the view with the join conditions and the fields. After activating it, I have checked the data and it's correct. The problem appears when I try to create a custom datasource based on this table, the following error appears:
Invalid extract structure template ZXXX of DataSource ZXXX.
You tried to generate an extract structure with the template structure ZXXX. This operation failed, because the template structure quantity fields or currency fields, for example, field AMOUNT refer to a different table.
I have checked the quantity and currency fields in order to add the reference tables and fields. For example:
0AMOUNT: ref table: EIPA; ref field: BWAER.
The problem is that I don´t know how to join both tables (EIPA and my Zview) because the key is different in the tables and only non relevant fields like Net Price appear in both tables.
If I add only the field EIPA-WAER, the data selectedis not correct, obviously.
Please, what can I do? Any ideas?
Thanks in advance! Any help will be more than welcome. Thanks!

Hi all,
I have created an Infoset but the problem persists. If I only join the tables I need, when I generate de Infoset, a warning appears telling that some fields (currency and quantity) will not be filled. At this point, if I execute de datasource in RSA3, the number of records is correct but these fields are empty.
If I add the tables that appear in the warning message, the number of records extracted is 0, because these "auxiliar" tables only contain information about currency units but they don't have the same key values so thay cannot join.
I have a question now... the tables that I have to upload into BI are also Z Tables. What happens if I ask my development team to add currency and quantity units in these tables? I think my problem will be solved if unit fields appear in the original tables. Would it be enough?
Any suggestions on it?
Thanks in advance!

How to create a Custom DataSource ?

Hi to everybody,
I'm a little confused about creating a custom DataSource that i need to create a player
that shows as a video some jpeg images retrieved from an input stream.
question 1:
do i have to store all the images in the data source ? or i can just set the current image every time i rereceive a new image ?
question 2:
can i link my JpegInputStream to my custom data source in order to read the images ?
thank you in advance
ps please help me .. it's really important.

Unable to create Custom Datasource on AFRU -Invalid extract structure error

Hello folks,
All SDN experts I need urgent help with an issue here.I am trying to create a custom datasource on a view on AFRU table.But i am getting this error 'Invalid extract structure template ZAFRU_V ' , i know it could be cuz of the field SMENG which is refrenced to AFVV tables MEINH field.My boss needs to have this field.I would like to know what can i do to get it, do i need to write a user exit, will that help or not. Please tell me what to do.
Thanks,

i tried what you asked me to do, this was my joing condition
AFRU     MANDT     =     AFVV     MANDT
AFRU     AUFPL     =     AFVV     AUFPL
AFRU     APLZL     =     AFVV     APLZL
But then what i ran into was if the counter (APLZL) was 0 or blank it wouldnt get that data for me.That means i will loose hundreds or thousands of records if they have confirmation and routing number of ops in order but no counter.Please assist.
And to answer is open so please any one who sees this and knows the answer please reply.
Thanks.

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,

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.

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.

Pramod

Dump during extraction for the custom datasource (ZFI_GL_14).

Hello all,
we are using Ecc 6.0 and we havent installed Enhancement Package 3. However our requirement is to create a custom datasource (ZFI_GL_14) similar to the standard one (0FI_GL_14). Initially we created the custom DS same as the standard one with the extraction method using Function Module. By default custom DS was assigned with extraction method F2. By running a program we changed F2 to F1 to resemble the standard one and made it as delta enabled as specified in the standard extractor.
when we started extracting the custom DS using RSA3, we encountered so many errors and resolved them. However still we are getting some more errors which requires your help.

2.also lt_fldlist_s should bring the field names.
As this is for New GL line item datasource, I am not sure what fields should lt_fldlist_s and what table name , and wheretab value should come , so that the function module can extract the data.
Kindly help me to get an insight into this issue and to get it resolved.
thanks,

Hi Frank,
yes I agree. That was the first question that came to me in my mind. However, the job was handed over to us, and we were able to exactly create the custom DS , FM and Function groups as similar to the standard one and everthing got activated perfectly. But during extraction, it throws the dump.While debugging, the function module is not able to pick the value for the 3 fileds which I stated above in one of my queries. The main extractor for this Datasource is FAGL_GET_SI_DATA and it uses the extract structure FAGLPOSBW.This Main function module in turn calls one more FM, FAGL_GET_LINE_ITEMS by exporting below parameters.
CALL FUNCTION 'FAGL_GET_LINE_ITEMS'
          EXPORTING
            i_block_data = 'X'
            i_block_size = sd_max_lines
            i_selection = lt_select_int
            i_fieldlist = lt_fields_int
            i_initflag   = i_initflag.
      ELSE.
From my observation , the above statements i_selection = lt_select_int and i_fieldlist = lt_fields_int should contain/pass the value to the line items FM, FAGL_GET_LINE_ITEMS.In the above thread also I mentioned I didnt get the value for ld_dbab_syntax, lt_fieldlst_s and ld_where_tab. I believe it is simply because i_selection and i_fieldlist is not getting the value from lt_select_init and lt_fields_init respectivelyImport parameters for this FM is as below.
I_BLOCK_DATA     TYPE     C
I_BLOCK_SIZE     TYPE     SY-TABIX
I_SELECTION                           TYPE     GUSL_T_SELECTION
I_FIELDLIST                           TYPE     GUSL_T_FIELDS
I_INITFLAG                           TYPE     GUSL_BOOL
I_CHANGED_RECORDS      TYPE     GUSL_BOOL
export parameter for this FM is as below.
FLAG_CURSOR_OPEN     TYPE     FLAG
Changing parameter for this FM is as below
C_T_FAGLPOSE     TYPE     FAGLPOSE_T
where FAGLPOSE means Fields for Reading Data: Line Items: New General Ledger.GUSL_T_SELECTION is the same type like DDIC table type FB_T_FIELD_SELECT_OPTIONS which will have Fieldname and selection option range.GUSL_T_SELECTION is created within the type group GUSL as mentioned below.
TYPES: BEGIN OF GUSL_S_SELECTION,
       FIELDNAME LIKE DFIES-FIELDNAME,
       T_RANGE   TYPE GUSL_T_RANGE,
       END   OF GUSL_S_SELECTION,
       GUSL_T_SELECTION TYPE GUSL_S_SELECTION OCCURS 20.
wherein
FIELDNAME LIKE DFIES-FIELDNAME,
DFIES: --> DD Interface: Table Fields for DDIF_FIELDINFO_GET. Also GUSL_T_FIELDS refers to DFIES.

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 in custom datasource - Purchase

Hi,
I am creating a custom datasource on purchasing using EKBE and EKET tables.
can any one tell , how to capture the delta of this datasource using eg., PO number, time stamp etc.,
Thanks
Sridhar

Hi Sridhar,
In order to create a custom data source follow:
1. Create a view on both the table.
2.go to rso2
3.select transactional data source ( if data fetched is transactional ).
3 . give view name
4. click on generic delta.
5. give delta specific field :
( if yuo have chosen timestamp or calendar day then it is required that your view should have these fields.)
or else give any other field according to whic you want the delta to be generated.
6.select after images ( applies to DSO )
or select additive (applies to dso and infocube )
save ->again save
your custom data source is created.
reward points if helpful

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

Master Data With Custom Datasource.

Hi,
When we create the custom datasource ( Transactional ) and load it to the BW, it has master data field Company code,Cost Centre.
Doubt is when the company code, Cost Centre are coming from the transactional Custom data source(with data), do we need to still load the Master data from the Master data data sources .
What are points to be considered and known?
Please provide your valuable inputs to understand this condition.

Hi Adhvirao,
As suman said there is master data sources like customer master, vendor master...
check there is SAP predefined master datasources like 0CUSTOMER_ATTR..
First you have to load master data and the only transaction data.. then only you can get rid of data mismatches in the report.
Otherwise there will SID collusion, then it might be chaces you won't get the proper result in reports.
Regards,
Ranganath.

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,
Saveen

Custom DataSources With JMF

I am having trouble creating a custom DataSource. Even following this example (http://java.sun.com/products/java-media/jmf/2.1.1/guide/JMFApp-DataSource.html#86181) I still get a NoProcessorException. Do I have to implement anything else to get a custom DataSource to work, even if the one I am trying to uses an existing implementation of PullSourceStream, PullBufferStream, PushSourceStream, or PushBufferStream?
To go into further detail, I am attempting to create a DataSource that pulls data in from a byte stream instead of a file. Unfortunately, I have had no luck. Any help would be greatly appreciated!

Incidently, I cannot find any examples on building my own MediaHandler (which is appearantly what one needs in order to properly use a custom DataSource ?).
Anyone have an example? Is it relatively simple?
