Write Table to XL sample

Greetings to all NI application engineers and programming experts.
I have downloaded a write table to XL spreadsheet from the labview example. This sample added a new sheet to the existing file whenever a new table of data is transferred. If I want to save the new data again and again on the same worksheet, how could I do it? Sincerely hope that anyone could help me modify this sample to cater to the above needs as I do not have knowledge with ActiveX property and methods control. Thanks a lot.

  • How can I assign filename for the Write Table to XL.vi from NI sample?

    The sample from NI (Write Table to XL.vi) works fine, but always it open a "Book1" as defult then askes to save it later!
    I try to modify it and assign a meaningfull filename so that the user does need to save or rename it ... but I failed!
    Is there an easy way to modify this sample for that purpose? Can anyone help me?

    Hi ATC,
    I modified your vi, it creates an XLS file with the filename you assign (no dialog box).
    You get a dialog box only if the file already exists, but this is normal; if you don't want to have it either, simply delete it progammatically before creating the new one.
    Good luck,
    Alberto

  • Write Table to Excel

    I have taken the write table to xl.vi example and modified it so that I can use it. Write now I have a vi setup that displays certain columns of data that I am pulling from a txt file in both a graph and a table. Then I am trying to write this table to xl by following the example, however I get the error 97 when running the vi, and a blank excel workbook opens up. I think this has something to do with how the table I have created is used to try and enter this into excel. Any help you can provide would be greatly appreciated. Thanks.

    Error 97 is "LabVIEW: Null Refnum was passed in as input."
    You might wanna check whether the Automation Refnum is linked to the correct ActiveX class in the "Open Excel" VI.
    In your diagram, as Dennis pointed out, it has no dataflow. The row header and column header in your table are both empty as well. That results in three for-loops doing nothing. Wire your "Hour" variable directly to the input of the third loop instead. Also at the end of the program, you should close all opened references regardless of the "Completion Task". Put only the invoke node "application quit" in the case structure should do.
    Hope this helps.

  • Read/write table rather than calling BAPI

    Hi experts,
    I need set "Deliv. compl." flag as true .
    set NOMOREGR='X' when call BAPI_GOODSMVT_CREATE
    I want to read/write table rather than calling BAPI, but I don't know what's the table,what's the field.
    who can tell me?  How to find that?
    I pressed "F1" key in the checkbox (Deliv. compl. flag), then I clicked "Technical infomation", and I got "MEPO1313-ELIKZ", but it's a struct, not a table.
    Many thanks.

    I happened to recall something about MEPO from way back when.... and the "EPO" suggested EKPO and EKKO to me...
    However, I utilize WHERE-USED function a lot.  For instance, in this case, one might go into SE11, enter ELIKZ into the data type field, and select WHERE-USED.  This takes a bit of research since field ELIKZ is used often as completion indicator, LOEKZ as deletion indicator, etc.
    Best wishes,

  • Write table to SAP (BAPI, ActiveX...)

    Hello everybody,
    I have to do a SW that interfaces with SAP. I already have functions to login/out, read/write a single parameter, and read a table (all this trough BAPI ActiveX), but I’m not able to write in a SAP table.
    Does somebody already have done this job?
    Many thanks for any advice!

    I find SAP doc not so easy to transpose into LabVIEW code...
    Error happends like this:
    Login SAP: OK (work also in other programs)
    Add name of the specific BAPI function to be used: OK (work also in other programs)
    Input of several single parameters (strings): OK (work also in other programs)
    Input of 2 Tables (2x same VI): see code here enclosed. No error at this point. (never tested in other programs)
    Call of BAPI function (code tested OK in other programs) but returns an error "SYSTEM_FAILURE"
    Reading some return parameters (code tested OK in other programs, but do not works here because of System_Failure)
    Close ref and Logoff  (code tested OK in other programs)
    I enclose also in this mail an image showing the main VI (named "Créer contenu HU.vi") making all this procedure. You will see that the error comes after the function call.
    I'm not a SAP pro (and far away!), but the SAP specialist has tested the BAPI function (with php?) and the function works. So the first suspect code is the one attached here.
    Please ask me if you need more details.
    Many thanks in advance, best regards,

  • Acquire, display, and write data at 50 samples per second

    I have a vi running on a PXI which samples data using two 4220's (all 4 channels) and one 6031 (only 6channels).  I am acquiring data at 100 samples per second, but only need to write the data out at 50 samples per second.  The data needs to be displayed at a minimum of 10samples per second.  The problem is that the VI can not get 50samples per second writen to the file, it writes about 20 to 30samples per second.
    I dont know if the issue is displaying the data which is holding up the writing at 50samples per second or if it is something else in the VI.  I have moved the writing of the data to the outside of the while loop, but this did not help enough to reach 50samples/sec.
    Is it better to change the waveform data types to dynamic waveforms?  Would this increase speed of operations?

    Galen,
    Looking at your vi, I would recommend writing to your file in a different way.  The function you are using is actually opening, writing, and then closing the file every time you call it.  This greatly increases the amount of resources being used.  Take a look at the Cont Acq to Spreadsheet File.vi example and note that the file is only being opened and closed once.  The data is being written to the file during execution of the program, and then closed when the app is done running.  The example is done in traditional DAQ but you should be able to do something similar with DAQmx.  Try this and let me know if it helps.

  • Write Table to file (Excel or otherwise) in background

    Hello All,
    I am new the ABAP programming with only self training (two weeks).  I have searched forums for 4 days trying to find usable solutions.  I am writing directly to see if someone can point me in the correct direction.
    I have to output data from multiple tables into a file for transmission to another site.  My first attempt used the OPEN DATASET and a TRANSFER.  This works in interactive and in background mode, but the lines in file are truncated at 255 characters, this was true for both TEXT mode and BINARY mode.
    My second attempt used the GUI_DOWNLOAD to put the file into a tab delimited excel type format.  This gets all the fields and all the characters, but can't be run in background mode.
    How can I get a file that has a  line lenth of about 600 characters into a file for FTP?
    Thanks for assistance,
    Steven M Engel
    Attempt 1 - Problem is that the lines in p_file are limited to 255 characters.
        OPEN DATASET p_file FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.
       OPEN DATASET p_file FOR OUTPUT IN BINARY MODE.
        IF sy-subrc = 0.
          LOOP AT gt_delivery.
            TRANSFER txt_delivery     TO p_file.
          ENDLOOP.

    It is very difficult to get FM GUI_DOWNLOAD to run in the background. There is a white paper out there that describes how to do it, but I never heard of it actually being done successfully.
    The TRANSFER statement should work for wider records. You can check that it does by reading the file back in and then looking at an offset (rec+255).

  • Report Writer (Table FAGLFLEXT)

    I have created a group of reports in Report Writer where the table of data that use is the FAGLFLEXT.
    But, I have a problem for the Companies that use local currency CLP are in the table FAGLFLEXT, Report Writer in thousands of CLP and in Transactions FBL3N/FS10N the amount appears correct,  them attached an example.
    Table FAGLFLEXT     CLP   12.000,00
    Report Writer             CLP   12.000,00
    FBL3N/FS10N     CLP     1.200.000 ( Amount Correct)
    As additional information I can comment to them that the same does not happen to the other currencies (USD, MXN, BRL, PEN), them attached example
    Table FAGLFLEXT     USD  10.000,00
    Report Writer             USD  10.000,00
    FBL3N/FS10N     USD  10.000,00 ( Amount  Correct)
    It applies a solution but this it affects all the currencies to me, it modifies a Seth of ratio of the currencies and (HSL * 100) multiplies percent but to this it affects me change in all the currencies.
    Friendly, since I can do so that the Report Writer shows the whole amounts to me of CLP and that they do not affect the other currencies.
    Thank you very much to all u2026.!!!!!

  • Trigger to write only current individual sampled data to spreadsheet

    Hi, I am new to labview and I have a task that I am not capable of completing.
    My task is to read the values of two encoders simultaneously. I am reading the encoders using 2 counters. I am generating a clock using a third counter, allowing the encoders to use that clock for simultaneous sampling.
    Then, using a physical push button, I want to trigger writing the angular positions of the two encoders to one spreadsheet file, making sure that ONLY both values at that same sample are written to the file. I want to write the ouputs of the encoders everytime I press the trigger, multiple times during execution, appending the new values to the same spreadsheet file. (Each column in the spreadsheet file should contain several outputs of each encoder: Column 1 for Encoder 1 and Column 2 for Encoder 2)
    My problem is not knowing how to implement the writing of the encoder outputs at the same sample the trigger is pressed.
    I hope it is clear what I am trying to do and I would greatly appreciate your help.
    Please find the working VI attached.
    Thank you,

    Hi again
    Thanks for your replies.
    I followed your advices but I still need some adjusting for my code to work the way I intend it to.
    To be more specific, I am building a robotic coordinate measuring arm where I aim to place the end-probe of the arm on an object and get the (x,y,z) coordinate at that specific point. To get the coordinate, I have to get the angular positions of the encoders (placed at the degrees of freedom of the arm) at that specific point. Hence, I will be using this physical trigger to signal writing the encoder values, at that specific point, to a spreadsheet file. After registering one point, I would like to be able to move the end-probe of the arm to another point and to follow the same procedure. (Use the trigger to signal writing the angular values of that new coordinate to the same spreadsheet file).
    The problem with placing the trigger in the while loop is that on each iteration the value of the encoder is saved, which is not what is required of my task.
    I want the trigger to be somehow independent of the while loop because of my application I described above.
    I hope this makes it clearer as to what I am aiming for.
    I modified my VI as you advised (find modified VI attached), and I will be gratefull if you can help me further with this task.
    Thank you,

  • Crystal report : can't add table in the samples provided by SAP

    Hello,
    I tried to add tables in the generic samples provided  by SAP.  I used the database expert and just added a new table but when I save the report in SAP and want to run it it is blank.
    Is there another way to add a table ?
    BR

    Already tried all those tricks!
    My question is concerning the standard layouts provided by SAP (downloaded from marketplace). The idea behind those reports is that you can use them as Templates. 
    The tables are not hardcoded with the table.field name but with a specific syntax that allows you to use those templates in any type of document (ex : you can use the template of sales order for delivery and invoices). The problem is that if you add a new table the report doesn't work!
    Thank you for the response anyway.
    Best Regards,
    Arnaud
