How to set (unix) permissions when creating a file in SAP ABAP?

Question

you would think this would be obvious, but searching through documentation, SAP forums, Googling, etc., I've been spectacularly unsuccessful. I'm creating a file in ABAP on a solaris filesystem using the following code:

OPEN DATASET p_file FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.

the resulting file is owned and grouped according to a pre-defined admin user, which is fine, but the sticky wicket is that the permissions are set to 660/rw-rw----, meaning I can't examine the results. is there a way (possibly using that vaguely defined TYPE addition?) I can specify the resulting permissions on the new file?

thanks!

Was it helpful?

Solution

this works in 4.6B:

        CONCATENATE 'chmod ugo=rw ' lc_filename
          INTO lc_chmod SEPARATED BY space.
        CALL 'SYSTEM' ID 'COMMAND' FIELD lc_chmod.

Hope this helps.

Cheers, Heiko

OTHER TIPS

Go to SM69, create a logical system command, you could call it ZCHMOD.

Map that command to chmod, then call with the proper parameter (man chmod on the command line is your friend).

CALL FUNCTION 'SXPG_COMMAND_EXECUTE'
  EXPORTING
    commandname                   = 'ZCHMOD'
    additional_parameters         = l_par
    operatingsystem               = l_os
  TABLES
    exec_protocol                 = it_log
  EXCEPTIONS
    no_permission                 = 1
    command_not_found             = 2
    parameters_too_long           = 3
    security_risk                 = 4
    wrong_check_call_interface    = 5
    program_start_error           = 6
    program_termination_error     = 7
    x_error                       = 8
    parameter_expected            = 9
    too_many_parameters           = 10
    illegal_command               = 11
    wrong_asynchronous_parameters = 12
    cant_enq_tbtco_entry          = 13
    jobcount_generation_error     = 14
    OTHERS                        = 15.

Obviously, that would be a 2 step process, but it works.

In RZ10 add parameter install/umask. Default value is 007, you can change it: 000, 002... So, the files created will be -rw-rw-rw-, -rw-rw-r--...
