Is there a way to search the application log (SLG1) for a particular message?

Question

Is there a function module (or any other way) that searches the SLG1 application log for a particular message? I.e. the inputs are the message class and ID and maybe a date range.

Answer 1

Yes, search for BAL_* functions. In general you might need this sequence of functions:

• search on DB for these logs

  CALL FUNCTION 'BAL_DB_SEARCH'
    EXPORTING
      i_s_log_filter = g_s_log_filter    "here are the selection filters
    IMPORTING
      e_t_log_header = g_t_log_header
    EXCEPTIONS
      OTHERS         = 0.
  

• load logs from DB

  CALL FUNCTION 'BAL_DB_LOAD'
    EXPORTING
      i_t_log_header = g_t_log_header
    IMPORTING
      e_t_log_handle = g_t_log_handle
      e_t_msg_handle = g_t_msg_handle
    EXCEPTIONS
      OTHERS         = 0.
  

• display logs: get variant which creates hierarchy according to field DETLEVEL

  CALL FUNCTION 'BAL_DSP_PROFILE_DETLEVEL_GET'
    IMPORTING
      e_s_display_profile = g_s_display_profile
    EXCEPTIONS
      OTHERS              = 1.
  

• create a display profile

• use grid for display if wanted

  g_s_display_profile-use_grid = p_grid.
  

• define up to which level the tree should be expanded

  g_s_display_profile-exp_level = 1.
  

• set title of dynpro

  g_s_display_profile-title     = TEXT-004.
  g_s_display_profile-head_text = g_s_display_profile-title.
  

• set report to allow saving of variants

  g_s_display_profile-disvariant-report = sy-repid.
  

• when you use also other ALV lists in your report,please specify a handle to distinguish between the display variants of these different lists, e.g:

  g_s_display_profile-disvariant-handle = 'LOG'.
  

• call display function module: We do not specify any filter (like S_LOG_FILTER, ...,T_MSG_HANDLE) since we want to display all logs available

  CALL FUNCTION 'BAL_DSP_LOG_DISPLAY'
    EXPORTING
      i_s_display_profile = g_s_display_profile
      i_t_log_handle      = g_t_log_handle
      i_t_msg_handle      = g_t_msg_handle
    EXCEPTIONS
      OTHERS              = 1.
