  • Extract data from a scanned PDF Chart

    Hi,
    I have a scanned PDF chart, which shows linear relationship between two variables. Is there a way to extract data from the scanned PDF using Acrobat?
    I want to avoid error in my calculations by eyeballing the data. Using "Measuring tool" may be an option, but wanted to ask whether any forum members have a better and efficient way to extract data, which can later be used in a spreadsheet software.
    As an example, please refer to the attached link, I will like to extract data from Figure 6 in this document: http://www.seas.columbia.edu/earth/wtert/sofos/nawtec/nawtec13/nawtec13-3164.pdf
    FYI, I have Acrobat X installed on my Windows computer.
    Thanks in advance for your help.

    Using AA9 Pro I was able to use the TouchUp Object Tool, right click and open the graph in Photoshop. From there, or Paint and another image editor, one might be able to clean it up or re-create the paths. The gray values are too close for it to be simple.
    The measure tool does not seem a good choice; although you see measurement lines, it would not actually produce the line you desire, until maybe, just maybe you flattened annotations, a feature within Fixups, perhaps limited to the Professional version.
    IMO, it is a fairly linear graph with only a variation at the 10 Power (MW). You eyeball is as good as mine at this one; the actual values may be available from the authoring entity.

  • Extract data from Servo Tune in MAX

    Hello,
    I would like to know if it's possible to extract the data gathered in ServoTune in the MAX utility.  I am using the "jog" feature to view the velocity profile with the built-in graph.  I'd like to extract this data, and do my own analysis on it.  Is it possible to extract/export/save this data to a text file?
    Thanks.

    Masselin,
    unfortunately there is no way to export the data from the graphs in MAX. If you want to analyze these data, you should implement the "Jog Axis" feature in your IDE (C, LabVIEW,...) and gather the data there.
    I'm sorry that I don't have amore convenient answer for you.

  • 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.

  • 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).
