Hi, I don't understand your issue.

You can display multiple messages in a view using the message manager. Only need to call several times to the corresponding method...

Can you explain your problem with more details ?

Hi Prabhakar,

Let you wanna display multiple types (error, warning, success) messages, just create your own structure follows:

Types: Begin of ty_messages,

               message type string,

               message_type type char01,

          end of ty_messages.

Data: lt_messages type table of ty_messages,

          ls_messages type ty_messages.

Data: lv_error_true(1).

**** Append the messages in your required places. 

ls_messages-message_type = 'S'.

ls_messages-message = 'This is success message'.

append ls_messages to lt_messages.

ls_messages-message_type = 'E'.

ls_messages-message = 'This is error message'.

append ls_messages to lt_messages.

ls_messages-message_type = 'W'.

ls_messages-message = 'This is success message'.

append ls_messages to lt_messages.

if lt_messages is not initial.

loop at lt_messages into ls_messages.

if ls_messages-message_type eq 'E'.

     lo_message_manager->report_error_message(

               message_text = ls_messages-message ).

lv_error_true = 'X'. """" if required to stop the process.

elseif ls_messages-message_type eq 'W'.

     lo_message_manager->report_warning(

               message_text = ls_messages-message ).

elseif ls_messages-message_type eq 'S'.

     lo_message_manager->report_success(

               message_text = ls_messages-message ).

endif.

endloop.

if lv_error_true = 'X'.

     RETURN.

ENDIF.

endif.

I hope this would resolve your issue.

Prabhakar,

Create a structure at se11 level like below:

and write the below code in your WDP component:

data:      lt_messages type table of ZST_WD_REPORT_ATTR_ERROR_MSG,

             ls_messages type ZST_WD_REPORT_ATTR_ERROR_MSG.

ls_messages-attribute_name = 'ATTRIBUTE1'.

ls_messages-element           = <lo_element>.

ls_messages-message          = 'Display message 1'.

append ls_messages to lt_messages.

ls_messages-attribute_name = 'ATTRIBUTE 2'.

ls_messages-element           = <lo_element>.

ls_messages-message          = 'Display message 2'.

append ls_messages to lt_messages.

ls_messages-attribute_name = 'ATTRIBUTE 3'.

ls_messages-element           = <lo_element>.

ls_messages-message          = 'Display message 3'.

append ls_messages to lt_messages.

***** Display messages at a time.

if lt_messages is not initial.

     loop at lt_messages into ls_messages.

           lo_message_manager->report_attribute_error_message(

                    attribute_name = ls_messages-attribute_name

                    element           = ls_messages-element

                    message_text  = ls_messages-message ).

          clear: ls_messages.

     endloop.

return.

endif.

**************** above is the sample for attribute error message, you can use this for all types of messages by pointing respective parameters.

hope this will resolve your problem.
