This article explains how to generate a csv or comma separated file and export data from Microsoft Dynamics AX 2012 by X++ code.

Applied on: Dynamics AX 2012 R3 CU9.
Prerequisite: Basic Dynamics AX 2012 programming knowledge.
Target audience: AX programmers.
Assumption: You are familiar with Dynamics AX 2012.

I prepared a x++ job here which will guide you how to generate a csv file with a header and one sample line. If you have one header and multi line, you may keep line in a while.

static void exportDataInCSV(Args _args)

{

    Dialog          dialog  = new Dialog();

    DialogField     dialogFieldFileSave;

    Commaio         file;

    container       line;

    FilePath        TempPath;

    dialogFieldFileSave     = dialog.addField(extendedTypeStr(FilenameSave),"File path","Help text goes here");

    dialog.caption("Caption goes here");

    dialog.filenameLookupFilter(['csv','*.csv']);

    if(!dialog.run())

        return;

    if (dialogFieldFileSave.value() == '')

    {

        error("Please set up the location for export file.");

        return;

    }

    TempPath = dialogFieldFileSave.value() + '.csv';

    #define.filename(TempPath)

    #File

    file = new Commaio(#filename , #io_write);

    if( !file || file.status() != IO_Status::Ok)

    {

        throw error("File Cannot be opened");

    }

    //Put headers

    line = ["CardNum","Amount","IssueDate","ExpiryDate","IssueBy","CustAccount","Description"];

    file.writeExp(line);

    //Put a sample line

    line = ["C_476786","100.00","05/26/2015","03/25/2016","John Smith S","Cust_0000034","Description"];

    file.writeExp(line);

    info(strFmt("File exported successfully. Please find it at %1",TempPath));

}
