Extract data from a subvi in a subpanel

Hi,
I'm modifying a huge existing vi-program (300+ subvi). Among other things I want to change the main vi and the user interface. My main goal is to have a menu bar (listbox) to the left and sub-panel to the right where subvis are opened whenever the user change selection in the menu bar. This, I can do with invoke nodes.
The challenge for me (and for you - if you accept) is to save the changes done by the user so they reappear when the user re-select that particular point in the menu.
Secondly, I would like/need to extract the settings from the subvis (when the user makes another selection in the menu) to the main vi so I can use the settings in other subvis.
Thirdly, I would like the subvi, open in the subpanel, to be in run mode, for the interface to be interactive.
I have mange to make a draft-vi, but I fear that it will require too much computer power and memory when it has to be able to call 30 different subvis. I also feel that the data/setting extraction is a bit clumsy and could become quite messy when expanded. My solution to make the called subvi interactive is fairly simple, but I hope another solution could appear in the discussion.
FYI, the program has to be made executable at some point.
I really hope someone can bring my some inputs or comments to my draft-vi.

You have a very good idea. I have used it many times myself. But let's think things through a bit more:
You want to be able to pass data between plugin modules - which is a Good and Useful Thing.
When you get this running it would be another Good and Useful Thing to be able to reuse the architecture. Wheel reinventing is a Bad Thing.
If the user interface knows what the data look likes that is being passed between plugin VIs, it will limit your ability to fulfill Point #2.
So let's take things one small step further and say that the data passed between the plugins is private data that the plugins hide from the user interface (henceforth to be know as the reusable application framework).
In this scenario the reusable application framework has only one job: Opening plugins, starting them running and putting them in the subpanel. (ok so that's three things - nobody expects the Spanish Inquisition).
So how do you pass data? Functional globals, databases, events, notifiers, depending upon the details of what the plugins do, there are a bunch of alternatives.
Mike...
PS: The event for handling the selection should have all the code in it for managing the plugin. You can fire the event programatically during initialization to get things started. Likewise the list of options for selection can be populated programatically when the application starts.
PPS: Now that the reusable application framework has so little to do, give some thought to some other things it might have time to do - like providing a standardized error reporting mechanism; implementing a standardized menu structure that the plugins can hook into if they need to; or providing some common on-screen buttons that the plugins can use.
PPPS: Databases are a Very Good Thing.

Unable to extract data from an AS/400 system.

Hello experts.
We are trying to extract data from an AS/400 system but not having any success until now.
I´ll write down you the stepts that we have followed until now:
1.- Create a DB Connect between both systems
2.- Create a Source System from AS400 in the workbench under DB Connect Directory
3.- Generate datasources from tebles specified in the schema of the connection
break point -
At this point, we had a problem with some tables with at least one fieldname containing character "Ñ".
After asking some possible solutions to SAP, the told us this is not supported, as the system can´t have any object with character "Ñ", so the transfer structure was unable to activate with this fields in the datasource.
--- end of brek point --
4.- After those issues, we´ve decided to implement, in another schema, views from those tables which had the fieldnames with that character "Ñ", changing them to an "N".
5.- We´ve created another source system with that schema, and user than can see that schema.
6.- To be able to see those views, in transaction RSDBC, we had to deactivate the two checkboxes in the first window ( Choose tables and Choose views) .
7.- Right afeter, we could generate correctly the datasources from this logical tables.
8.- We have designed the hole dataflow for this datasources and everithing went rigth.
9.- But wen we tried to execute the infopackage to extract data from those logic tables, we cannot get any registers. Acctualy the charge remains yellow after the job have finished.
Please, I would appreciate any help you could give us on this problem.
Thank you very much
Regards
Joaquin

I´d like ti add something to this thread, and maybe clarify a littel bit the question.
The only way that the BW system recognizes those logical tables, through transaction RSDBC is checking out the two boxes on this transaction, "Select Tables" and "Select Views".
I don´t know haw these logical tables have been created, bus does this mean that the are not neither tables or views as BW understand them.
Please, if someone knows anythin about this, answer to this thread.
Thank you very much.

What key fields should i set in DSO extracting data from 2LIS_02_ITM

hi experts
i extract data from 2LIS_02_ITM into a DSO, i know the DSO isn't a must, becoz the 2LIS_02_ITM delta type is ABR, but i want to keep the info in change log.
so, what the key fields should i set in the dso? just ebeln and ebelp is enough?
hunger for ur advice and thanks a lot!

If you extract ITM toa DSO you cannot maintain a log of every change....the data will come ....but when the data must be activated the reference of the ebelp ebeln will remain only a single record....if you want to maintain all the data you must create another field in extractor with you can difference all the changes for one single ebelp ebeln...

How can I join 3 tables while extracting data from SAP R/3?

I have 3 tables with the following columns
Emp table (emp)
emp_id
emp_name
emp_add
Dept table (dept)
dept_id
dept_name
dept_loc
Location table (loc)
loc_id
loc_name
Now. If I want to select data from loc_id = 10 and emp_id between 2000 and 3000
How to join these three tables while extracting data from R/3
join condition
loc.loc_id = dept.loc_id
and dept.dept_id = emp.dept_id
and loc.loc_id =10
and emp.emp_id between 2000 and 3000.
Could any one let me know the procedure to extract this data into BW system.

Hi,
shouldn't your join condition be:
loc.loc_id = dept.DEPT_LOC
and dept.dept_id = ??
If you can join the three tables then create a generic datasource (RSO) based on a view (create your view with your join in SE11).
Enable the loc_id and the emp_id as selectable in the datasource so you can then select the values from a BW IPack.
hope this helps...

Extracting data from Z-table from SAP R/3 to BW

Hi all
I want to extract data from a Z-table from SAP R/3 system to Bw system. Currently I am on BW 3.5. Since it is a Z table I dont have a standard extractor for it & I dont knw how to create it. Can anyone provide me with the step-by-step documentation of how to extract data from a non standard SAP table????

Hi
You need to create Generic Datasource on the Z-Table you want to get data from
Go to RSO2 transaction to create generic datasource .
You need to give technical name of datasource under datasource type you want and click on create. Then you can give descrption and Application component under which u want see the datasource,
enter the z table name under view/ table and save.
here you can click on check boxes to make fields hidden or selection fields.

Generate Insert Statement Script to Extract Data from Table in Oracle 7i

Hi all, I have an old Oracle legacy system that is running for over 15 years.Every now and then we need to extract data from this table@ ORacle 7i to be imported back to Oracle 10G.
My thoughts are to create a script of Insert statements in oracle 7 and that to be deployed back to Oracle 10G.

Extract data from Essbase with HAL to a flat file

Hello,
I would like to extract data from Essbase with HAL.
I use the essbase Adapter with the "Extract Data" Method.
All is working when I use only the essbase Adaptater and configure it.
But I want to have a variable on my Years dimension.
I have to fill "Years member port" and "Years Criteria port" of my essbase Adapter with variable.
I have a "v_year" and "v_year_criteria" variable. I fill "v_year" with "FY05" but I don't know how fill my "v_year_criteria" variable.
Thanks a lor for answer.

If you are in 9.3x, I would recommend using the DATAEXPORT calc script function. You just FIX on what you want to export (including substitution variables), and then fill in some parameters and it writes a file. Look in the DBAG.

Extract data from Query to a Flat File - scheduling in the background

Hi All,
We need to extract data from a query to a flat file periodically, but each time 10 separate executions based on 10 profit centers, to get the separate files.
So, we have PC1, PC2, ... PC10 Profit centeres.
We have Query1, with profit center variable.
We have created 10 variants for Query1 so that we can execute for 10 profit centers.
Now, we have used RSCRM_BAPI to execute the Query1 and write to a flat file. Now we are having a problem in getting this feature used to execute the query automatically for 10 different varaints.
Thanks in advance,

Extracting data from Excel To Illustrator javascript or vbscript

Hi all-
I was wondering if there was a way to extract data from Excel to be used in Illustrator. I know there is an option of variables and xml, and I don't want that. I've seen and tried out how to read illustrator and write to excel, and I get that. What I would like to do is pretty much the opposite:
1.Pre-fill in an Excel file(.xls,.csv, doesn't matter) with data such as a filename in column 1 and (Replacement Text) in column 2 and close manually.
2. Run script(VBSCRIPT,Javascript, doesn't matter)
3.For each column in Excel file where cell in first column is not empty, open Illustrator Template with placeholder of "DWG" textframe and replace the frame titled "DWG" with Replacement text from Excel in Column2.
4, Save each to a PDF file and name file with text from Excel Column1(Filename)
In a nutshell, there will be a single illustrator template with a premade textFrame with a name of "DWG". Excel will contain two columns, one for the filename to be named and one for the relative text to replace with the placeholder in AI. I hoped I explained this well enough without causing too much confusion. Thanks in advance.
Filename
Replacement Text
test1.pdf
DWG01
test2.pdf
DWG02
test3.pdf
DWG03
test4.pdf
DWG04

As text… \n is new line character and \r is return character. I can't remember which excel uses but they both equate to a line/paragraph… I very quickly threw together an example for you…
#target Illustrator
textToPDF();
function textToPDF() {
          if ( app.documents.length == 0 ) { return; }
          var doc, csvFile, i, fileArray, opts;
          csvFile = File( '~/Desktop/ScriptTest/Test.csv' );
          if ( !csvFile.exists ) { return; }
          fileArray = readInCSV( csvFile );
          doc = app.activeDocument;
          opts = new PDFSaveOptions();
          opts.pDFPreset = '[Press Quality]';
          // Here we loop the main array
          for ( i = 0; i < fileArray.length; i++ ) {
                    // Here we get the second item of sub array i
                    doc.textFrames.getByName( 'DWG' ).contents = fileArray[i].[1];
                    // Here we get the first item of sub array i
                    doc.saveAs( File( fileArray[i].[0] ), opts );
function readInCSV( fileObj ) {
          var fileArray, thisLine, csvArray;
          fileArray =[];
          fileObj.open( 'r' );
          while( !fileObj.eof ) {
                    thisLine = fileObj.readln();
                    csvArray = thisLine.split( ',' );
                    fileArray.push( csvArray );
          fileObj.close();
          return fileArray;
I haven't tested it but it should be close…?

Is it possible to save / extract data from a MS SQL database 2008 using lookout 6.2?

Is it possible to save / extract data from a MS SQL database 2008 using lookout 6.2?
Now a days we are saving / extracting data in a excel spreadsheet, but we would like to do that using a database because it is better.

You can use ODBC connection to work with SQL Server database.
Use SQLExec object to execute the SQL statement. Here is a KB about the SQL statement.
http://digital.ni.com/public.nsf/allkb/4ADEEA04CD24AE0B862565E20002A16F?OpenDocument
To write data to spreadsheet is more straightforward because Lookout has built-in spreadsheet object. But you need to write SQL statement by yourself to interact with other database.
To read the data back is the same way. Just use "select" SQL statement to query. You can use Datatable object to query.
The "Data Source" can be "DSN = data source name;". The data source name is configured in Control Panel->Administrative Tools->Data Sources(ODBC).

Need suggestion on how to extract data from a table

Many years ago, I wrote many Perl scripts to increase my work productivity.
Now I am starting learning Java, Javascript and PHP for some purposes. Just wrote a simple html2txt java program.
Now I need experts' suggestion for one specific purpose - extract data from a html table. One of the examples is here: http://mops.tse.com.tw/nas/t06sa18/200902/A02_2454_200902.htm
I need to extract datum from the table and make some analysis. (Txt is in Chinese, sorry)
What is the best way to code it? Java, PHP or other? If Java, any suggestion what classes/module and approach to use?
Thanks very much.

What is the best way to code it? It this a one shot (one time only task)? Then the best way is whatever way you are most comfortable with and which works.
If on going then I doubt language choice matters but using a html parser rather than attempting to parse it yourself is going to help in any language.
And are you starting with html files or starting with a http server? The two are very different.

How to Extract data from a Request management tool to Apex to avoid working on Excel reports

Client uses a ticketing tool,I donot know what is the database for the tool,but I would like to know the best way to extract data from the tool to pex so that we can eliminate working on Excel reports.These excel reports are basically the open request log,resolved tickets,aging tickets etc,currently we work on many excel reports,can we achieve this in Apex ,if so how do we achieve this.Then we would like to use this report and prepare multiple charts,how the above two requirements can be mapped.

A very important function for the system will be - one sends an email in certain format to a dummy email address, then some data will be extracted from the email based on the pre-defined format and inserted into the database my APEX application is using.
Any idea on how I can make it happen please? I agree that this is not really an Apex question, but a more general PL/SQL question.
There are many approaches, all boiling down to one of these two:
1) Push: Some process in the mail server sends/forwards information to your database when new mail arrives.
The language/tools used to do this, and the way it would connect to your database, depends on your environment (what is your operating system? mail server? existing middleware/tools? security protocols used? etc.).
2) Pull: Some process in the database contacts the mail server and polls for new information.
Ie. some PL/SQL code would communicate with the mail server. Again, it depends on your environment (what is your operating system? mail server? existing middleware/tools? security protocols used? etc.).
For example, if you are using Exchange 2007 or newer, it has a web services API:
http://msdn.microsoft.com/en-us/library/dd877045.aspx
The challenge here will be to build the correct SOAP requests from PL/SQL, and to handle the security protocols used.
