Sap CRM : WebUi specfic Messages handling

We often come across the requirement when we need to suppress the specific messages on web ui which we not find in the message container CL_CRM_GENIL_MESS_CONT_MANAGER .This Messages we will get from the reference of class cl_bsp_wd_message_service.

1. The messages which are added to the global message container can be deleted by resetting the class :

DATA: lr_core TYPE REF TO cl_crm_bol_core,

  lr_msg TYPE REF TO cl_crm_genil_mess_cont_manager.

  lr_core = cl_crm_bol_core=>get_instance( ).

*Create a instance of message container

lr_msg = lr_core->get_message_cont_manager( ).

  *Reset the container to delete the messages

  lr_msg->reset( ).

2. But when we want to delete any specific messages type from web ui using the
reference of class cl_bsp_wd_message_service.

Read all the messages that are added by reference of class cl_bsp_wd_message_service by below code snippet:

DATA: lr_msg_srv       TYPE  REF TO     cl_bsp_wd_message_service ,     
            lv_ref_kind       TYPE  crmt_object_kind,

            lv_msgidno      TYPE symsgno,

           lt_idno              TYPE bal_r_idno,

          ls_idno              TYPE bal_s_idno,

           lv_activity_guid    TYPE crmt_object_guid,

           lr_messages          TYPE REF TO bsp_wd_message_tab,

          lr_entity                 TYPE REF TO     if_bol_bo_property_access,

          lv_guid                 TYPE REF TO     data.

      lt_message             TYPE crmt_orgman_symsgno_tab,

       lr_mess_obj      TYPE REF TO cl_crm_message_obj_bt.

    FIELD-SYMBOLS  :
<lt_message> TYPE bsp_wd_message_tab,

  <ls_message> TYPE bsp_wd_message.

 
FIELD-SYMBOLS:  
<l_guid>        TYPE crmt_object_guid.

  CONSTANTS:

    lc_msgid                     TYPE symsgid VALUE ‘R11’.

lr_msg_srv = me->view_manager->get_message_service( ).

CALL METHOD lr_msg_srv->get_messages

EXPORTING

   iv_msg_type = ‘W’

RECEIVING

rv_result = lr_messages.

*We got all the required messages in lr_messages

ASSIGN lr_messages->* TO <lt_message>.

*Then call the below function module to delete the specific messages

lv_msgidno = ‘185’.

INSERT lv_msgidno INTO TABLE lt_message.

  LOOP AT lt_message INTO lv_msgidno.

   CLEAR ls_idno.

   ls_idno–sign= ‘I’.

ls_idno–option = ‘EQ’.
ls_idno–low–msgid = lc_msgid.
ls_idno–low–msgno = lv_msgidno.
APPEND ls_idno TO lt_idno.
ENDLOOP.

* The below FM ‘CRM_MESSAGES_DELETE’ is used the delete the specific messages from the web ui

CALL FUNCTION ‘CRM_MESSAGES_DELETE’

   EXPORTING

* it_r_msgid = ‘R11’

   it_r_msgidno = lt_idno

   iv_ref_object = lv_activity_guid

   iv_ref_kind = lv_ref_kind

       EXCEPTIONS

   appl_log_error = 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.

ENDIF.

In the above function module we have to pass the specific
message id number in the required passing parametr also order_guid and ref_kind
in order to delete the specif messages.

Hope it will be going to help for those who gets confuse while handling the messages on webUi .

Happy Learning

Cheers !!
