SAP standard function modules to upload / download to / from application server

[Former Member]

Summary

The document will give insights to two SAP standard function modules which can be used to upload / download files to / from application servers. There are few blogs on creating custom function modules to accomplish the task. Using the standard function modules will help in reducing this effort.

Data declaration:

Parameters:  p_file type sapb-sappfad.        “On presentation server
parameters : p_path type rlgrap-filename.    “On Application server

At selection-screen on value-request for p_path.
"Start to check current directory
  call function '/SAPDMC/LSM_F4_SERVER_FILE'
    exporting
      filemask         = ' '
    importing
      serverfile       = p_path
    exceptions
      canceled_by_user = 1
      others           = 2.

  if sy-subrc <> 0.
    p_path = p_path.
  endif.

  The above codes will popup the below screen for selecting the folder in application server:

 

a) Use ARCHIVEFILE_CLIENT_TO_SERVER function module to transfer file from presentation server to application server.

Code snippet:

call function 'ARCHIVFILE_CLIENT_TO_SERVER'
      exporting
        path       = p_file
        targetpath = p_path
      exceptions
        error_file = 1
        others     = 2.

    if sy-subrc <> 0.
      message id sy-msgid type sy-msgty number sy-msgno
              with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    else .
      message 'successfully transfered' type 'S'.
    endif.

b) Use ARCHIVEFILE_SERVER_TO_CLIENT function module to transfer file from application server to presentation server.

Code snippet:

data : w_path type sapb-sappfad,
       w_file   type sapb-sappfad.

parameters : p_path1 type rlgrap-filename.

parameters : p_file1 type rlgrap-filename.

move p_path1 to w_path.
move p_file1 to w_file.

    call function 'ARCHIVFILE_SERVER_TO_CLIENT'

      exporting

        path       = w_path

        targetpath = w_file

      exceptions

        error_file = 1

        others     = 2.

    if sy-subrc <> 0.

      message id sy-msgid type sy-msgty number sy-msgno

              with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

    else.

      message 'successfully transfered' type 'S' .

    endif.

Conclusion

Request you to try out these function modules and get back on improvements, if any.

Cheers!
