The scenario that I speak of occurs when you are debugging a pop-up window. When you are working with a pop-up window there is no convenient transaction window where you can turn on the debugger. So what do you do?

Simple.

Create a new file; lets call it debugger.txt and populate the contents of the file with the following lines:

[Function]

Title=Debugger Session

Command=/h

Type=SystemCommand

Save the file and leave it on your desktop.

Now when ever you get to a pop-up window that you want to debug simply drag the debugger.txt file in to the window and you will activate the debugging session.

Happy hunting!

For instance in this post I’ll show you a quick example of how to hide a on-screen component based on user selection.

PARAMETER:  cb_a AS CHECKBOX DEFAULT 'X'
            USER-COMMAND batch MODIF ID ida,
            cb_bAS CHECKBOX DEFAULT 'X'
            USER-COMMAND batch MODIF ID idb.

AT SELECTION-SCREEN OUTPUT.

  LOOP AT SCREEN.
    IF screen-group1 = 'IDA' AND cb_b NE 'X'.
      screen-active = 0.
      MODIFY SCREEN.
    ENDIF.

    IF screen-group1 = 'IDB' AND cb_a NE 'X'.
      screen-active = 0.
      MODIFY SCREEN.
    ENDIF.
  ENDLOOP.

This example will hide each of the check boxes depending on the selection of the other check-box. If both are selected then both are visible, if one is un-checked then the other is hidden.

The active attribute controls the visibility of a particular screen component. Explicitly: 0 = hidden, 1 = visible.

1. Using transactions SM49 and SM69 set up and test a new OS command that you wish to execute.  For the purposes of this post I’ve set up an executable command ZSAPCAR32.
2. When I was setting up the new command I’ve selected the option to add additional parameters to the command.
3. Once tested and satisfied you can add a new function module [SXPG_COMMAND_EXECUTE] to your report that will call preset executable command.

data: g_rlog                TYPE btcxpm OCCURS 0.

CALL FUNCTION 'SXPG_COMMAND_EXECUTE'
       EXPORTING
            commandname                   = 'ZSAPCAR32'
            additional_parameters         = <additional parameters>
            operatingsystem               = <system you specified in SM69>
       TABLES
            exec_protocol                 = g_rlog
       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.

if sy-subrc eq 0.
    LOOP AT g_rlog INTO g_warlog.
*     display command output
      write g_warlog.
    ENDLOOP.
endif.

The above code will execute your OS command and display the results.

data: l_select TYPE sapb-sappfad.

CALL FUNCTION 'WS_FILENAME_GET'
       EXPORTING
            def_filename     = l_select
            def_path         = ' '
            mask             = ',*.*,*.*.'
            mode             = 'O'
            title            = 'Select filename to OPEN'(f05)
       IMPORTING
            filename         = l_select
       EXCEPTIONS
            selection_cancel = 1
            selection_error  = 2
            OTHERS           = 3.

This function will open up a pop-up window [standard to windows] allowing the user to select a file somewhere on their local comptuer.

In either case I am determined to get better familiarized with the things that I’ve forgotten.
