    Hi,
    You cannot just download and upload module pool programs .
    There are 2 different ways.
    1. Copy all the includes and and create the same in the target system. You can download and upload the the Screen.
      But GUI status you have to manually create.
    2. If you have completely saved the module-pool program in one Workbench request(including Z tables u have used) in the original system ,just  release the workbench request and copy the data file and co file and upload to the target system ( use CG3Y & CG3Z).
    If the workbench is a Local Request save it in a Transport of copies and then move.

  • How to download and upload BDC programs

    How to download and upload BDC programs from one instance to another instance? I would like to transport my BDC programs from one dev client to another Dev client not through transport like smartforms.(we can download smartforms to desktop and upload to someother client)

    Hi,
    No need to record again. You can save the recording session by generating the program in transaction SHDB. Then you can download the BDC program and upload to another SAP client using transaction SE38.

  • Download and upload files

    Hi!
    I need to develop an application where the users want to be able do download a RTF document, modify it, and save it back into the application. I know how to download a RTF document, stored as a BLOB in a table, so the document opens in a new window and the user can change it. Now, I won't the user to save the file on the disk and then upload the file through the upload page in the application, but rather to just click "save" in MS Word and close it, and then somehow the file should automatically upload in the database. Does anyone ever created something like this, using some Java Applet on the client PC maybe?
    Thanks for help,
    Alen

    Hello Mradul
    Thanks for your answer. I deleted all history (both from
    Internet and flash player). Now I have no problem downloading files
    but Internet still crash when I uploading files (I have not tried
    the other suggetions). I use Vista 32-bits. Maby Acrobat.com, when
    using Flash player 10, requires Vista 64-bits to work without
    problem? What do you think.
    I read at Adobe troubleshooting about a similar problem; that
    Flash player causes Internet to crash or freeze. Maby I should
    inform Adobe support about my problem.
    Thanks

  • How to download and upload SPRO configuration to and from local disk?

    Hello,
       I'm very new to SAP. Recently we had a problem while refreshing our QNA system from PRD. I knew there are some configurations, which do not have a transport and thus configured directly in QNA. These changes were not noted by mistake and after the refresh from PRD, we have lost these configurations.
      Is there any way we can save the SPRO configurations to local disk and upload them again? Are there any custom programs available? Please advice?

    The trouble with these kind of situations is that an applet runs on the client. If you want an applet to connect to a specific server (which means the client makes a connection to that server), you basically have to give the entire world access rights to that server. I don't think your friendly local administrator will be too happy with such a prospect.
    What you could do is put a man in the middle. Don't upload to the file server directly, but to for example the web server where the applet was downloaded from, for example by making a servlet available that takes a HTTP file upload. When that upload is complete, send the file from your man in the middle server to the file server using whatever method you like/have available/know how to code. In this situation only your web server needs access to the file server, which is far easier to secure.

  • Download and upload file

    in J2EE project,how can I upload a file and process it at server side,for ex.a picture,a text file(may be text need to be process)..
    how can I generete a file from server side,like .doc and user can download it

    Do a search for servlets generating MS Office files. There are packages that can generate .pdf, .xsl and .doc files.
    When users uploads file, you have access to file's name. Use filename extension to determine what kind of file it is.

  • How to download and upload FM?

    Hello,
    I want to copy a function module from one system to another. So i tried Upload/Download i.e. Utilities->More Utilities->Upload/Download.
    But while uploading the source code is only uploaded and not the tables, import/export parameters, etc.
    So what can be done to copy the complete FM.
    Thanks & Regards,
    Rahul.

    Hi Rahul,
    Up/Download will not do the job. Even when transport is not possible because there is no connection between the 2 systems I would still use this mechanism.
    Create a WB-request, add the FM to the request and release the transport request. Pickup the co-file and data file from your server and use transaction STMS on the receiving system to add the request to this system.
    Regards,
    John.

  • How to download and exe file?

    Hi - is there a way for a mac user to download an exe file - I'm needing to download some software from my internet company in Africa - it tracks my usage, important because here we pay per download - thus the software is a program that tracks usage so we don't go over our monthly amount . . . as most things here, there is almost nothing set up for macs . . . hence my query: is there a way to convert an exe file so that I can use it? THANKS, Autumn

    Hi Masego
    Downloading is easy - but if it's an exe file then you might not be able to make much use of it on OS X, as it won't run.
    To run Windows exe files on a Mac you need one of the following technologies:
    1. A version of Windows installed on a separate partition of your hard disk, using Boot Camp.
    2. A version of Windows installed using a virtualisation technology, such as Virtual Box.
    3. I'm told that "Mono" will allow you to run certain exe files under OS X but I've never tried it myself.  Mono is free and if you do a search for it then you might find someone who can give you more support.
