How to Set a Variable with data from Srouce Data Store

Hello ODI Experts,
I have created a Physical & Logical Schema and a Source Data store to pickup data from a database table.
On the other hand, I have a few variable that I will pass in a web service call (ODIInvokeWebService tool).
Would yo please guide how I can set variables from my source data store.
Thanks & Regards,
Ahsan

Hello Bos/Damodhar/ODI Experts,
Doesn't it gives me a less optimized approach picking one column per query (per variable)?
Lets say, I have to pick 35 columns from a table and put those in 35 variables...It would mean running 35 queries for fetching one record from the database table.
Doesn't it seem less performance effective (less optimized)..a little scary..any thing better that I can do to make it more optimized?
Another question, what if multiple new values have come in the DB table, since I am using Refresh Variable, would this variable have multiple values in it?
Thanks for all your help,
Ahsan

(Bash) How to set a variable with text from a file? [SOLVED]

I'm having a little problem.
I have textfile with a single line of text. What I want to do is set a variable with that line of text. How do I go about doing that?
A simple var="text" wont work in this case, since the text in the file changes with another script of mine.
Thanks in advance.

if you have a file with more than one line but you only want the first line you could use 'head'
VAR=`head -n 1 file`

How to set a variable value on the BPC Data Manager

Hello BPC Experts,
I'm creating a BPC10 NW version demo environment for our prospect customer.
I made a data manager to import BW data into BPC model from BW cube.
I need to import just one month data into BPC from the BW cube that has more than one month data.
When I run the data package manually, I can select a member of the time dimension prompt and I can import specific month data I want.
But, in a case where the program (data manager) runs by JOB monthly,
I can't select a member of the time dimension prompt manually.
So I want to know how to set a variable value to the time dimension prompt from a system date etc. automatically.
Are there any way to set a variable value to the time dimension prompt on the data manager automatically from a system date?
Or, do you have any other solution to import just one month data into BPC from the BW cube that has more than one month data by the data manager running on JOB ?
(without selecting a member of the time dimension prompt of the data package manually)
Thanks in advance,
Keisuke

Hi Gersh
Sorry for my late reply and thanks for your helpful information.
I tried the second way of your information and I could configure it.
And I 'll try first way of your information.

How to set a variable's value from job output

Can anyone point me at documentation on how to set the value of a variable based on the output of a job? We are running TES v6.0.2.153.
The Agent/Adapter is a Linux command line, so the Command could be for example:
echo foo
and I would like a variable named bar to contain the value foo. (Obviously in real life the variable value would be dependent on what the command output)
Thanks in advance,
Martin

One more nugget: to parse the response from a command from a UNIX/Linux agent for a specific string and store that in a variable, I followed Rami's advice and then had to find the string in the output.
The below example puts the first digit of a random number in the variable:
Job Command:
bash -c
Command Parameters:
"'echo' Random number is $RANDOM | perl -ple 's/.*Random number is (\d{1}).*/\1/'"
Note that your command itself (in this case "echo") cannot be put in the Command box, otherwise TES does not interpret the Command Parameters correctly. So you need to set the Command to "bash -c" (run the command in the parameter string), and enter your command and parameters within double quotes in the Command Parameters, with the command being run (in this case "echo") in single quotes at the beginning.
(I also had to make my .bash_profile run without any output to avoid it being prefixed to the variable value.)
Hope this helps,
Martin.

How to plot waterfall graph in vb6 from offline data

How to plot waterfall graph in vb6 from offline data?The data load from SQL Server Database.Thanks.

asrol,
If you look at the Plot Styles example in the folder I mentioned in the previous post there is a section of code there that you might want to refer to in order to recreate your data.
'=============================================================================
' Plot Curve Button Handler
'=============================================================================
Private Sub PlotCurve_Click()
    ' Create curve data
    Dim x(40)
    Dim y(40)
    Dim z(40)
    For i = 0 To 40
        x(i) = Sin(i / 3#)
        y(i) = Cos(i / 3#)
        z(i) = i
    Next i
In this example they create 3 arrays to represent the three dimensions of the array. For your case if you were to plug your data into two of the array (axes) that would give you the data for the channels, then you can simply input a constant for the third array it would produce a single line of your data as shown in your example GIF. You can then repeat this process for each set of data, with a new constant value for that third axis, and it should manually create a graph that will look something like you desire.

I want to set a variable with default value and can be changed by the user

hi,
i want to set a variable with default value and can be changed by the user, so i new a variable with setting : customer exit, single value, optional, ready for input.
in my customer exit code, i set a default value, eg. 20070530
when the variable screen popup, it display the default value 20070530, i changed it to 20070529, but it doesn't work , it still display the data in 20070530, how can i solve this problem?
your help is appreciated.

Liu,
As mentioned by Anil, you need to restrict your customerr Exit code to I_STEP = 1.
or.
<u>Open your Variable in change mode, in the Last Page os the Variable Maintenance you can provide default value. Note: you are doing same thing in Customer Exit. In your case no need of Customer Exit.</u>

I want to convert word documents to html using CTX_DOC.Filter.According to the documentation,I know I neednot set the 'Inso Filter'in the preference when creating index,but I must set enviroment variables for Inso Filter.
I found the following instructions for it in the 8.1.5 documentation,but I can't understand it well.Is there anyone can tell me how to set enviroments variables for Inso Filter on Windows2000 Server?(My DB version is 8.1.7EE)
Environment Variable Locations
All environment variables related to Inso filtering must made visible to interMedia Text. Set these variables in the following locations:
listener.ora file. This makes the environment variables visible to the extproc PL/SQL process.
The operating system shell from where ctxsrv server is started. This makes the environment variables visible to the ctxsrv process, which does background DML.
Any suggestions are apreciated

How to genetare reports(ssrs) with form library's data in sharepoint 2010

Hi,
How to genetare reports (ssrs) with form library's data in sharepoint 2010.I am saving infopath(2010) xml form data in form library.I have 500 and more forms in the form library( more forms can come in future).How to generate reports from this xml data (i
want to make it automate)? Reports should get updated automatically when any changes made to data and if new form entered in the library.
Please suggest possible solutions.I can not go for code base solution.( somthing SSIS, BCS or web service ....etc or anything else will be fine)
Thanks in advance.

Hi,
According to your post, my understanding is that you wanted to generate SSRS report with form library in SharePoint 2010.
In order to use the data stored on the InfoPath form, you need to add the controls on the form to be columns in SharePoint(This is the OOTB way without code).
You can add the control during the publish process:
Then when you create the SSRS report using the form library as the data source, you can use the fields just as the fields created in SharePoint.
There is a tool called InfoPath DB in codeplex, you can have a look at it.

Load Grid with data from System.Data.DataTable

Hi all.
A have a System.Data.DataTable e need load a grid with data from this DataTable.
How Load a Grid with data from System.Data.DataTable?

Hi Francisco,
actually i don't think that you can use a .NET datatable to fill a business one grid.
the business one has it's own datatable.
in c# it would look like this:
oForm.DataSources.DataTables.Add("MyDataTable");
((SAPbouiCOM.Grid)(oForm.Items.Item("grid").Specific)).DataTable = oForm.DataSources.DataTables.Item("MyDataTable");
oForm.DataSources.DataTables.Item(0).ExecuteQuery("SELECT Field FROM [dbname].dbo.TABLE");
((SAPbouiCOM.Grid)(oForm.Items.Item("grid").Specific)).CollapseLevel = 1;
((SAPbouiCOM.Grid)(oForm.Items.Item("grid").Specific)).AutoResizeColumns();
((SAPbouiCOM.Grid)(oForm.Items.Item("grid").Specific)).SelectionMode = SAPbouiCOM.BoMatrixSelect.ms_Single;
good night
