ABAP Code for loading the flat files kept at FTP locations

Hi all,
I need to automate the process of data loading via flat files with the help of process chains , with respect to which I require following help:
1. what steps should I follow to load the data with respect that whenever the new file comes in the directory of the ftp location start that process chain for data load.(Note : there is no fix time that when the new file will be coming)
2. Every time the new file will be having differnt name , then in that case how we will be fetching the new file which is require for data loading?
Thanks and Regards,
Neha

Hi Neha,
I have not worked on this or made this code.
Recently my onsite did it.
Try to find more gyan on this functiona module...'DX_GET_PHYSICAL_FILENAME'
Code is... write it in infopackge start routine.
DATA: v_filename LIKE dxfile-filename.
Below function module generates the filename with the complete path
based on the app server attached to the Central Instance
The logical mapping Z_INBOUND_EBIZ_PAYMENTS is maintained in the
transaction - "FILE"
  CALL FUNCTION 'DX_GET_PHYSICAL_FILENAME'
    EXPORTING
      i_filename             = 'Z_INBOUND_EBIZ_PAYMENTS'
    IMPORTING
      o_filename             = v_filename
    EXCEPTIONS
      not_registered         = 1
      logical_filename_error = 2
      OTHERS                 = 3.
  IF sy-subrc = 0.
    p_filename = v_filename.
    p_subrc = 0.
  ELSE.
    p_subrc = 4.
  ENDIF.

    May be if you are loading from Client work station you will face problem of this type.
    Try to check if any change in format in the file.

    thanks

    Hi Adnan,
    First you create a source system for flat file loading.
    Do this in RSA1 - Source Systems. Via context menu, create it in node "File".
    Then, goto the RSA1 - Datasources view. Choose the corrrect source system.
    Create a datasource and assign fields.
    Use your datasource to load data into infoobject, datastore using a transformation between the datasource and datastore.
    Create and schedule an infopackage to load to PSA.
    Create and schedule a DTP to load into target.

  • ABAP code for caliculating the demand variability

    Hi gurus,
    I need to calculate the the demand variability for the requested raw material,
    Demand Variability for raw materials is calculated by taking the standard deviation of 52 data points, each point representing the total consumption in a week.
    The raw consumption data contains negative figures on many days, resulting from inventory adjustment transactions.  Aggregate consumption to a weekly bucket to keep variability from being artificially inflated by any negative figures from adjustments due to physicals, poor practices, or cycle counts.
    Calculation
    Calculate the consumption for every week based on MSEG-MENGE where MKPF-BUDAT falls within the week bucket from Sunday till Saturday. This is the value Xn.
    SUM all 52 Xn values for every week. This is Y.
    Divide the Y/52 = Z
    Calculate for that year the standard deviation
    SQRT (((Xn-Z)2)/n)
    Can you any one give the code for this condition.
    Thanks in advance.

  • What is the code to load a .swf file in AS3 on the same layer?

    I'm new to AS3 and am trying to figure out the code for loading a .swf file on the same layer of the same page, thereby replacing all of the information. I don't want to put it on layer 2, etc. Another easy thing I can do in AS2 but am struggling with in AS3.
    thanks!
    Steve

    There are no 'layers' in AS3 - there is just the display list. You can use addChildAt to add things at a specific depth - thereby placing it behind or above something, but if you just use addChild it goes on top of whatever is currently there...
    Anyway - to answer your question, you can load a .swf with a Loader object like so:
    var l:Loader = new Loader();
    l.load(new URLRequest("myFile.swf"));
    addChild(l);
    You can wait for complete like was shown, but you don't have to. And this will not 'replace' anything - it just loads myFile.swf on top of anything currently being shown. If you want to 'replace' what's there you need to remove it first:
    while(numChildren){
         removeChildAt(0);

  • ABAP code for Hierarchy Loading from Flat File

    Hi,
    Can anyone give me some idea / ABAP code for generating parent - child relationships (NODEIDS) from a flat file and load into BW.
    Best regards
    Any insight into this development is highly appreciated

    Hi,
    also have a look at this how to to get informations about the file structure:
    https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/0403a990-0201-0010-38b3-e1fc442848cb

  • ABAP code for flat file path

    Hello,
    My hierarchy is loaded through flat file. This file is present in the application server.
    We have hard coded the filename path in our program in the production system as:
    DATA:p_fname LIKE rlgrap-filename value '
    A0001SAP\PACE_PRD\interface\BI\BO\PYD_PDL.CSV'
    Now, our pre production system is refreshed and hence after the refresh, the same path got copied in the pre production system and our process chain got failed as the path name is wrong. Same is the case in the development system.
    Please note: The file path is same in all the systems except the name of the system i.e.
    For development system, the name is PACE_DEV
    for preprodcution system, the name is PACE_PREPRD,
    for production system, it is PACE_PRD.
    Could anyone let us know, what global logic should be developed so that the process chain runs smoothly in all the systems?
    Thanks in advance for the reply.
    Regards,
    Nitin Chopade.

    Nitin Chopade,
    Put the path /file name on the selection screen.
    parameters: p_output(120). 
    Then use that selection-screen field in place of the hard coded value.
    You can then change the path / file name at will.
    or
    Change the file '
    A0001SAP\PACE_PRD\interface\BI\BO\PYD_PDL.CSV'
    to                      '
    A0001SAP\PACE_&SYSID&\interface\BI\BO\PYD_.CSV'
    Assign the hard coded value to a variable, w_variable.
    Before you use the file:
    replace '&SYSID&' in w_variable with sy-sysid

  • BAPI_PO_CREATE1 not able to create PO's for multiple rows from the flat fil

    Hi
    i am uploading PO's from a flat file into SAP using the BAPI_PO_CREATE1. Everything works fine if the flat file hast only one record.
    if the flat file has more than one record then while loading the second record the BAPI returns a error message. I am calling the BAPI in a loop.
    The strange thing is that if i load the second record individually the program is able to create the PO. So only when i have multiple records in the flat file i am unable to load the PO into SAP. I debugged and checked all the internal tables passed to the BAPI. All seems to have the data correctly but still the BAPI fails.
    any idea where i am going wrong?
    the code looks something like this.
    LOOP AT HEADER_ITAB.
       PERFORM FILL_HEADER_RECORDS.
    LOOP AT ITEM_ITAB WHERE EBELN eq HEADER_ITAB-EBELN.
         PERFORM FILL_ITEM_RECORDS.
    ENDLOOP.
      PERFORM CERATE_PO_VIA_BAPI.
    ENDLOOP.

    What is the error message. Are you trying something like this:
        LOOP AT T_DATA1.
          AT NEW LIFNR.
            READ TABLE T_DATA1 INDEX SY-TABIX.

  • Different formats of the flat file for the same target

    In our deployment, we use plugin code to extract the csv files in the required format. The customers are on same version of datamart, but they are on different versions of source database - from 3.x to 4.5 depending on which version of application they are using. In 4.0, we introduced a new column email in the user table in the source database. Accordingly, plugin will add the field in the csv file. But not all the customers will get the upgraded version of plugin at the same time. So ETL code needs to decide which data flow to process depending on the format of the csv file to load data to the same target table. I made the email field in the target table nullable but it still expects the same format of the csv file with delimiter for null value.
    Need help to achieve this. Can I read the structure of the flat file in DS or get the count of delimiters so that I can use a conditional to use different data flow based on the format of the flat files.
    Can I make the email column in the flat file optional?
    Thanks much in advance.

    You can add an email column that maps to null in a query transform for the source that does not contain this column. 
    Or else you can define two different file formats that map to the same file.  One with the column and one without

  • Can I combine two methods of code to load various SWF files into the same location

    I presently have a set up where a large SWF file brought on the stage by clicking small icons from the scrollable thumbnail menu on the bottom of the stage. All of it happens at the same frame with .xml loading file.
    Here is the code for constructing the ImageLoader(for thumbnails) and SWFLoader for (bigger SWF files)
    [CODE]
       function _xmlCompleteHandler(event:LoaderEvent):void {
       _slides = [];
       var xml:XML = event.target.content; //the XMLLoader's "content" is the XML that was loaded.
       var imageList:XMLList = xml.image; //In the XML, we have <image /> nodes with all the info we need.
       //loop through each <image /> node and create a Slide object for each.
       for each (var image:XML in imageList) {
        _slides.push( new Slide(image.@name,
              image.@description,
              new ImageLoader("loadingAssets/appThumbnails/slideshow_image scroller greenSock_mine/assets/thumbnails/appThmb_imgs/" + image.@name + ".jpg",
                   name:image.@name + "Thumb",
                   width:_THUMB_WIDTH,
                   height:_THUMB_HEIGHT,
                   //centerRegistration:true,//messes up the code as places SWFLoader in the upper left corner which is 0,0 coordinates
                   //x:260, y:320,//doesn't work here but works in line 69
                   scaleMode:"proportionalInside",
                   bgColor:0x000000,
                   estimatedBytes:13000,
                   onFail:_imageFailHandler}),
              new SWFLoader("loadingAssets/appThumbnails/slideshow_image scroller greenSock_mine/assets/images/" + image.@name + ".swf",
                    name:image.@name + "Image",
                    width:_IMAGE_WIDTH,
                    height:_IMAGE_HEIGHT,
                    //centerRegistration:true,//messes up the code as places SWFLoader in the upper left corner which is 0,0 coordinates
                    x:0, y:144,
                    scaleMode:"proportionalInside",
                    bgColor:0x000000,
                    estimatedBytes:820000,
                    onFail:_imageFailHandler})
    [/CODE]
    Here is what I would like to resolve. I have another section on the site with an image collage. Every image is a button. I want to script this each image on click to go to the label with ImageLoader and SWFLoader AND TO OPEN A UNIQUE SWF (ASSOCIATED WITH AN IMAGE CLICKED) ON THAT PAGE
    Previously this is what I did to achieve it. I would specify a String:
    [CODE]
    var sourceVar_ProductsPopUps:String;
    [/CODE]
    and then all my buttons will have their unique SWF assigned for them which opens at another labeled section ("prdctsPopUps" in this example):
    [CODE]
    function onClickSumix1PopUp(event:MouseEvent):void {
      sourceVar_ProductsPopUps="prdcts_popups/sumix1-popup_tl.swf";
      gotoAndPlay("prdctsPopUps");
    [/CODE]
    Then in the "prdctsPopUps" section I would specify that var string to bring up SWF files. The value of sourceVar_ProductsPopUps allows to load mulitple SWFs from the previous page.
    [CODE]
    loaderProductPopUps = new SWFLoader(sourceVar_ProductsPopUps,
    [/CODE]
    But I need both of them to be working at the same time. First there is a sectionA from where a user can navigate to specifically targeted SWF to section B's SWFLoader. Then in the section B a user has an option to bring up other SWF files into SWFLoader from the scrollable thumbs menu. Is there a way to combine these two lines into one:
    [CODE]
              new SWFLoader("loadingAssets/appThumbnails/slideshow_image scroller greenSock_mine/assets/images/" + image.@name + ".swf",
    [/CODE]
    and
    [CODE]
    new SWFLoader(sourceVar_ProductsPopUps,
    [/CODE]

    Thanks for looking into my issue.
    Unfortunatelly I am not so advanced in AS and do not complitely understand the logic of the problem. I will try to decribe my set up more precise.
    So, my main flash file is broken into labeled sections on the main time line.
    One of the sections is "Applications" It has an animated collage of images. Each image acts as a button and once clicked brings a user to a section called "ApplicationsPopUps".
    "ApplicationsPopUps" section has small image thumbnails scroll menu at the bottom of the screen and a large SWFLoader in the middle of the screen. User can click on an image in the thumbnails scroll menu and a corresponding SWF file will load in the middle of the screen in SWFLoader. User can click on left/right navigation buttons and preceeding/following SWF file will load in SWFLoader.
    Everything works fine (with your previous help)
    Here is the working code for the ImageLoader and SWFLoader (please let me know if you need additional code on the page):
    function _xmlCompleteHandler(event:LoaderEvent):void {        _slides = [];       var xml:XML = event.target.content; //the XMLLoader's "content" is the XML that was loaded.        var imageList:XMLList = xml.image; //In the XML, we have  nodes with all the info we need.        //loop through each  node and create a Slide object for each.       for each (var image:XML in imageList) {         _slides.push( new Slide(image.@name,               image.@description,               new ImageLoader("loadingAssets/appThumbnails/slideshow_image scroller greenSock_mine/assets/thumbnails/appThmb_imgs/" + image.@name + ".jpg",               {                    name:image.@name + "Thumb",                    width:_THUMB_WIDTH,                    height:_THUMB_HEIGHT,                    //centerRegistration:true,//messes up the code as places SWFLoader in the upper left corner which is 0,0 coordinates                    //x:260, y:320,//doesn't work here but works in line 69                   scaleMode:"proportionalInside",                    bgColor:0x000000,                    estimatedBytes:13000,                    onFail:_imageFailHandler}),                 new SWFLoader("loadingAssets/appThumbnails/slideshow_image scroller greenSock_mine/assets/images/" + image.@name + ".swf",                   {                     name:image.@name + "Image",                     width:_IMAGE_WIDTH,                     height:_IMAGE_HEIGHT,                     //centerRegistration:true,//messes up the code as places SWFLoader in the upper left corner which is 0,0 coordinates                   x:0, y:144,                     scaleMode:"proportionalInside",                     bgColor:0x000000,                     estimatedBytes:820000,                     onFail:_imageFailHandler}) 
    Thumbnails in the section "ApplicationsPopUps" and images in the image collage in the section "Applications" represent the same photographs. So when a user clicks on one of the images in "Applications" section it would be natural that that image will load in the "ApplicationsPopUps" section. However "ApplicationsPopUps" section presently has a working code (as sampled above) It looks too complex for me and I do not know hot to implement this feature. I do want to keep the functionality of the thumbs image scroller in section "ApplicationsPopUps" as it is now. But I want to add that when a user click on an image from section"Applications" then that particular SWF file will load in SWFLoader in section "ApplicationsPopUps" and then the present functionality can as well be exectuted. Presently it just opens on a first image in xml order.
    P.S. I see that you had a download link in your answer. How did you do it? I could also upload a small sample file with my problem. This way you could see all the set up right away.
