How to split the rows while data integration?

Hi All
Im a newbie to ODI. I just want to know whether it is possible to split the rows in the source datastore to populate the target datastore.
Consider a table, say
Target Table 1:
a - varchar
b - number
sometimes i may get the source file like this
source1:
c1 c2
a 1
a 2
b 1
c 1
c 2
c 3
or
source 2:
c1 c2 c3 c4
a 1 2
b 1
c 1 2 3
in case of source 1 , i can easily map the values directly to the target table. the problem is in the source 2 scenario. the number of values in one particular row is unknown. In this case is that possible to split the row and populate the target using ODI.
Many thanks

with interface i don't know but you can make an procedure which make this
like
Select c1,c2 from source2
where c2 is not null
union
Select c1,c3 from source2
where c3 is not null
union
Select c1,c4 from source2
where c4 is not null
this is an option if it doesn't work with Interfaces.

How to export the text edit data to excel file without splitting the data in excel file?

how to export the text edit data to excel file without splitting the data in excel file?
I have a requirement in SAP HR where in the appraiser can add comments in the area given and can export that to excel file. Currently the file is getting exported but the comments getting split into deifferent rows.
I want the entire comment to be fit in one row.
Please help.
Thank you

Hi,
if your text edit value is stored in 'lv_string' variable.
then before exporting the value to excel you have to remove CL_ABAP_CHAR_UTILITIES=>NEWLINE
that is '#' from the variable lv_string.
for that use code some thing like this.
REPLACE ALL OCCURRENCES OF CL_ABAP_CHAR_UTILITIES=>NEWLINE in lv_string WITH space.
I think this will do the trick.

How to obtain the row data in the component datatable?

if I want to edit a row data, and then know which row is edited in the component datatable, and how to do?
How to obtain the row data in the component datatable, and update it to database, not simplely edit a simple table
Any ideas? Thanks

Thank you very much for your help Alexander !
It's quite confusing when you leave Struts and try to adapt your projects for JSF for the first time...
I wanted to click on a row with a "onMouseClick" on the TR tag like I used to do in Struts/JSTL. But it seems to be impossible in a dataTable.
Ok then. I've added a column at the end of the row with an icon.
But eventually I didn't need to declare link parameters.
In my BackingBean I did like this :
public String selectEventForUpdate() throws IllegalAccessException, InvocationTargetException {
        PortletAgenda event = (PortletAgenda) JSFUtils.getInRequestMap("event");
        BeanUtils.copyProperties(this, event);
        return null;
   }JSFUtils.getInRequestMap(...) is a method I wrote in a util object :
public static Object getInRequestMap(String name) {
        Object res = null;
        Map requestMap=FacesContext.getCurrentInstance().getExternalContext().getRequestMap();
        if (requestMap!=null) {
            res=requestMap.get(name);
        return res;
} " event " is the name of the item in my dataTable list.
My backingBean has the same attributes as "event".
So when the page is reloaded I have a backingBean full with the selected properties to edit/update.
Thanks to your reply I realized that putting this form in the middle of the dataTable seems to be impossible.
So I put this form in a floating DIV in front of the table with a shadow.
It works :o) !
But I'm a little bit disapointed to be honest...
I used to build my web applications with Struts and JSTL and doing this kind of interface was really easy.
I've decided 3 days ago to convert into JSF because the "GUI Layer" seemed to be improved.
But now I realize that I cannot put a onMouseOver and onMouseClick on a row and I cannot display a different row in the middle of a table....
I think it's a shame because there is a facet for header and footer.
And it would be great if we could create our own personal facet that appears only if a condition is true.
For exemple " if the current item id is the same as the request parameter id then display the following facet content ....... (with a panel group and a form inside to update the row) "
It's easy to do that with JSTL thanks to c:forEach and c:if but it seems to be impossible to use JSTL tags like this during the dataTable iteration.
And JSF tags seems to have no logical tags like " if " or loops that can be nested in dataTable.
I really need to realize this interface (you click on a row then an edit form appears where you clicked).
Do I have to write a component myself that extends dataTable?
Do you know if writing such a component is hard to do for a beginner like me?
(I've juste discovered JSF 3 days ago and I've used Struts/JSTL for 2 years til now)
I'd be glad to have much advices from you about that.

How to make the exchange of data between 2 while loop in real time

hello
I have 2 while loop
the 1st while loop includes the data acquisition program
the 2nd while loop includes the control program
my question is how to make the exchange of data between 2 while loop in real time
I tried with the local variable and direct wiring between the 2 while loop
it does not work (there is a delay)
Solved!
Go to Solution.

Bilalus,
Queues are only good to transfer data if your application isn't deterministic. Since you are using Real Time, I am assuming that your application requires determinism. If you are using Timed Loops and you use queues to transfer data between your loops, you are losing determinism. In this case, you need to use the RT FIFO functions.

All 3 functions can be written in rpd too.In BMM layer, duplicate the date column ->Goto Column Mapping tab-> Expression builder ->Select Functions-> Calendar Date/Time Functions-> Select DayofMOnth function. Your logical column's formula will look like,

Hi,
Thanks for your answer.
(1) To use FPE1, I understand but it has to do 2 documents for this solution.
Old doc.
      Dr. Revenue          500
          Cr. student A/R 500
1st Create new doc
    Dr. student A/R 500
              Cr. student A/R due 1 250
                   student A/R due 2 250
2nd Manual clearing (old doc vs new doc).
      Dr. studen A/R 500
            Cr student A/R 500
(2) To use due date schedule
We use this one in fee calculation, It can be debit side or credit side. I don't know it depend on booked-cancelled module.
In the debit side we need to invoice student just one due.
So, I can't use this solution.

Hi,
Follow the below steps . Definately your issue will bve resolved.
Let us suppose you are printing following fields
PH &v_text&
PH &v_text1&
PH &v_text2&
you will get the output as you expected.
and if you have any conditions for these fileds
/: if v_text is not initial.
PH &v_text&
/: endif
PH &v_text1&
PH &v_text2&
if you have data in each field then you will get output as expected .
But when v_text is initial.
the data will be moved up wnhich is happening in your case.
so what you need to do is?
/: if v_text is not initial.
PH &v_text&
/: else
PH (Here you need to mention empty line with same paragraph format
/: endif.
PH &v_text1&
PH &v_text2&

How to split the report into different versions view 1 agent delivery

Hello
I have a scenario where I need to send a dashboard to multiple users. The user information are stored in the table like the following:
USER Day Car Pay Type Cost Email
USER1
-10
-2
Honda
Customer Pay
500
[email protected]
USER2
-4
-1
AUDI
Customer Pay + Warranty
1000
[email protected]
USER2
-4
-1
PORSCHE
Customer Pay + Warranty
1000
[email protected]
Now I have a dashboard call Car, on this dashboard I have prompts like Date, Car, Pay Type, Cost, pretty much the same name as the columns in the above table. I have also set up session variables to pick up users based on the log in.
Now for user2, he is getting 1 email, which is the dashboard with both Audi and Porsche on there. Instead, he wants to 2 attachments, 1 for Audi and 1 more Porsche. Is there a way to achieve this using 1 agent?
Please let me know how to split the result sets based on user records in the table
Thank you

Hello,

How to split the Multi Provider

HI All,
Please give me the steps How to split the Multi provider and also let me know how to find the multi provider is parellal or series?
Thanks
Vasu.

Hi
If you have huge volumes of data, logical partitioning (splitting into multiple data targets based on a time characteristic) is always recommendable. You can choose to so only for the cube (split into 3 cubes) and have the suitable code when loading from the ODS's.
Else you can split the ODS's as well and have the code in the update rules from source system to the ODS's. Either ways, once you choose to split...you have no choice but to use a multi provider to report on these splits.
During the execution, query is automatically multiple sub queries and these sub queries read the partitioned cubes in parallel. This would increase the performance of reports. Hope this helps!

How to setup mail client in Data Integrator 11.7 to make use of mail_to()

How to setup mail client in Data Integrator 11.7 to make use of mail_to() function.
I am using mail_to() function in one of my job to know the status of source file. If source file is not ready, our DI job should fail and send mail notification with reason for failure.
But mail_to() function is not sending any mail. I guess I need to set up email client.
Any one please help to resolve this issue.
Thanks
Phani

From the DI documentation that comes with the installation:
To use this function, a mail client must be installed and running on the Job
Server computer that calls the function. The login account for the mail client
must have the same user name and password as the Data Integrator service.
The type of client varies by the operating system:
u2022 If the Job Server is on a computer running the Windows operating
system, then the mail client must comply with MAPI (message application
programming interface). In addition, the mail client must be configured as
the default mail client. For example, Microsoft Outlook is a MAPI-based
mail client.
If the Job Server is on a computer running the UNIX operating system,
then the mail client must be mailx-compliant.
So:
Mail client installed and configured and set as default
Mail client uses the same credentials as the job server service
Or use another function: smtp_to();
If still not working or you are not allowed to use an installed mailclient on your box, then try Blat: http://www.blat.net/
