Message logs duplicating during round trip

[former_member193460]

Hi Experts,

     i have done a message print at the top of the application and the set up of the area is as below.

Window INIT method:

METHOD wddoinit .
  DATA: l_api_mycomp TYPE REF TO if_wd_window_controller.
  DATA: l_wd_message_area TYPE REF TO if_wd_message_area.
  l_api_mycomp ?= wd_this->wd_get_api( ).
  l_wd_message_area = l_api_mycomp->get_message_area( ).
  l_wd_message_area->set_display_attributes( i_for_all_instances = 'X'
   i_use_toggle_area  = 'X'
   i_show_only_current = 'X'
    ).
ENDMETHOD.

Print method is inside view controller which is called where ever the message needs to be printed.

  DATA: lo_controller TYPE REF TO if_wd_controller.

lo_controller ?= wd_this->wd_get_api( ).

CALL METHOD wd_this->lo_message_manager->report_t100_message
        EXPORTING
          msgid                    = <lfs_messages>-id
          msgno                    = <lfs_messages>-number
          msgty                    = <lfs_messages>-type
          p1                       = <lfs_messages>-message_v1
          p2                       = <lfs_messages>-message_v2
          p3                       = <lfs_messages>-message_v3
          p4                       = <lfs_messages>-message_v4
          is_permanent             = abap_true
          VIEW                     = 'V_DASHBOARD'                        " View Name
          controller_permanent_msg = lo_controller
        RECEIVING
          message_id               = lv_msg.

The problem i am facing:

The message log is duplicated evertime there is a round trip on the page.(no code inside wddomodify method)
please help me with tips

Thanks & Regards,

Hi Tashi,

Are you getting message duplicated again on subsequent action PRINT button, you have set the messages as parmanent, hence old message remains as it is.

Replace :       is_permanent                  = abap_true

with         :       is_parmanent                = abap_false

Hope this helps you.

Hi Rama,

     if i do that , then for every round trip i loose the current message and its available only in log.

i want to retain the message till i do another print method , thats why i have made is_permanent = abap_true.

when a user does any round trip operation like changing view layout .. the current message section is emptied. i want to retain the current message and at the same time dont want any duplicates to be copied to the log.

Thanks & Regards,

Tashi

Hi Tashi,

I got your point

I suggest you to clear messages in PRINT method before reporting any messages. So that it clears all existing messages.

1.   "======================================= 
2.   "Clear messages from message manager 
3.   "======================================= 
4.   wd_this->lo_message_manager->clear_messages( 
5.     EXPORTING 
6.       including_permanent_msg = abap_true 
7.   ). 

Hope this helps you.

Hi Rama,

     Clear_message clears only the current messages but not from the log. the messages are getting duplicated on the log.

when i keep the message as permanent, any round trip copies the current message to the log even though the same message is already present in the log.

Thanks ,

Hi Tashi,

To delete messages from message log, use the method reset_messages( ) as below

wd_this->lo_message_manager->reset_messages( i_keep_current = 'X' ).

the above statement clears the messages from only log and keep the current messages untouched.

Hope this helps you.

Hi Rama,

     i already tried that, but it clears the log altogether ..i want to delete only the duplicates but the log should remain.

Hi Tashi,

You cannot delete only the duplicate messages from log as each time the message is generated with a unique id.

I suggest you to reset the log when user presses the PRINT button. so that old messages gets cleared and new log gets generated.

Hi Rama,

     Really appreciate your help, i have communicated this to my client. The would want the message to be permanent and can bear with the duplication of log entries on round trip .

Thanks & Regards,

Hi Tashi,

If you still looking for avoiding the reporting of duplicate messages, I would suggest you the below workaround solution... use the method WDDOMODIFYVIEW( ) method

May not be very cleaner in approach.

• Get the messages from message area using method GET_MESSAGES( )
• Now, sort the internal table based on message text " err_message "
• Loop over messages internal table and remove the duplicate message comparing message text using method REMOVE_MESSAGE( )

Sample:

if lv_action_name = 'PRINT_MESSAGES'.

          data lt_messages type if_wd_message_manager=>ty_t_messages.
          data ls_messages like line of lt_messages.
          data ls_messages2 like ls_messages.
          data lv_msg type string.

          lt_messages = wd_this->lo_message_manager->get_messages( ).

          sort lt_messages by err_message.

          clear: ls_messages2, lv_msg.

          loop at lt_messages into ls_messages.
               ls_messages2 = ls_messages.

               if     lv_msg = ls_messages2-err_message.
                    wd_this->lo_message_manager->remove_message( msg_id = ls_messages2-msg_id ).
               endif.
               at new err_message.
                    lv_msg = ls_messages2-err_message.
               endat.
          endloop.

Hope this work around approach helps you.

Rama
