ABAP – Export Transport request to local file system

SAPAll development or customizing in SAP is written into a transport request unless it is a local object not intended to be transported ($TMP package). Sometimes it might be useful to backup your development but in SAP this task is quite complicated to export all programs, classes, standard texts, …

Therefore there is an option to export the whole development encapsulated on a transport request level. And that’s what this article is about – exporting development encapsulated in a transport request to local file system.

Export of the whole transport is possible either manually(see Manual export) or using your own program (see Automatic export)

Manual Export

  1. Note down the name of your transport

    The name of transport request you are going to backup is in format XXXKYYYYYY (e.g. A1DK012ABC).You can find your transports using TCode SE09.

  2. Find the transfer directory of the SAP system

    Transport request consists of two parts:

    • one header field (co-file)
    • one body file (data-file)

    Once a transport is released, these files are written on SAP file system. To be able to download them, it’s necessary to know the path on SAP file system where they are placed.

    Using TCode AL11 you can access the directory parameters on your SAP system.

    The transport directory can be found under “Directory Parameter” called DIR_TRANS – note down the corresponding “Directory” (e.g. \usr\sap01\saptrans).

    The header and body files are stored in different directories on the server:

    • If you display details of the DIR_TRANS entry (double click on it) it shows its content.
      The entries we are looking for are two sub-directories called “cofiles” and “data”.
    • The header file with the naming syntax like KYYYYYY.XXX (e.g. K012ABC.A1D) should be placed in directory cofiles (double click to open the directory) .Now you have the cofiles directory (e.g. \usr\sap01\saptrans\cofiles) and the header file name (e.g. K012ABC.A1D)
    • Similarly you will find the body file of your transport in sibling directory data (e.g. \usr\sap01\saptrans\data) and the file name with prefix ‘R’ (e.g. R012ABC.A1D)

    If the files and directories mentioned above can’t be found, either there are different sub-directories defined in your system for transports or the transport request release failed.

  3. Download the files

    To download the two files mentioned in previous steps from SAP application server to local file system you can use the standard function module ARCHIVFILE_SERVER_TO_CLIENT which can be called/executed from TCode SE37.

    It takes two importing parameters:

    • source path including the file name (path to file on SAP file system)
    • target path (directory on the local file system where the downloaded file will be placed to)

    This means you have to call this FM twice – first to get the transport request header file and second to get the body file. These files can subsequently be used to be imported to another SAP system (this requires special authorization – most probably not granted to basic users/developers)

If such backup action needs to be performed more often or even needs to be automated it might be good idea to write own program for it – such program is available in the next section.
