Why does MESSAGE not work in Web Dynpro?

[Former Member]

Hello! I'm new to Web Dynpro for ABAP.

When I add the code as below to method WDDOMODIFYVIEW without any conditions of judgment, I thought it could pop up a box just like in a report program. However nothing happens!

MESSAGE 'test' TYPE 'I'.

I want to know why this sentence of code didn't work? And what should I do to realize the same function?

Thanks a lot!

Hi Shelwin,

The error reporting in Web Dynpro ABAP is done using message areas. You need to insert a message area UI element into your view.

Following link contains step by step information on how to create a message area UI element and trigger custom messages.

Here is the link again : http://webdynproabap.wordpress.com/2012/07/08/message-handling/

But still i will list down the steps:

- Insert a message area UI element into the view

- Wherever you want to show the error message use the following code, the message will be displayed in the message area.

DATA: lo_api_controller TYPE REF TO if_wd_controller,

          lo_message_manager TYPE REF TO if_wd_message_manager.

lo_api_controller ?= wd_this->wd_get_api( ).

CALL METHOD lo_api_controller->get_message_manager

     RECEIVING

          message_manager = lo_message_manager

         .

* Display error message in message area

CALL METHOD lo_message_manager->report_error_message

     EXPORTING

          message_text  = 'Error Message'

          .

There are few more things to be kept in mind. You can declare only one message area in a view. If you want declare standard text elements you need you a assistance class and you can get text from that assistance class.

Refer to following link if you need to store text elements in assistance class.

Hi,

You can't use the ABAP message syntax in webdynpro. If you want to display the message go through the below steps,

DATA:

        lo_api_controller  TYPE REF TO if_wd_controller,

        lo_message_manager TYPE REF TO if_wd_message_manager.

lo_api_controller ?= wd_this->wd_get_api( ). 
CALL METHOD lo_api_controller->get_message_manager .
RECEIVING message_manager = lo_message_manager. 
* report message CALL METHOD lo_message_manager->report_error_message.
EXPORTING message_text = 'Please enter correct address type'. 
like this we have many types of message as follows, and we can call this message using the code wizard,
REPORT_ATTRIBUTE_ERROR_MESSAGE (Parameter PARAMS)
REPORT_SUCCESS (Parameter PARAMS)
REPORT_WARNING (Parameter PARAMS)
REPORT_ERROR_MESSAGE (Parameter PARAMS)
REPORT_FATAL_ERROR_MESSAGE (Parameter PARAMS)
REPORT_ATTRIBUTE_EXCEPTION NO (Parameters ELEMENT, ATTRIBUTE_NAME)
REPORT_FATAL_EXCEPTION
REPORT_ATTRIBUTE_T100_MESSAGE (Parameters P1, P2, P3, P4)
REPORT_T100_MESSAGE (Parameters P1, P2, P3, P4)

Hi Shelwin,

You cannot use the standard MESSAGE syntax in the webdynpro,

You can use the wizard and generate the message code

• Open the method in which you have written the MESSAGE syntax
• Click on WEBDYNPRO WIZARD button
• Open general tab
• select Generate Message radio button
• Press F4 in the field method, select 'REPORT_SUCCESS' and press OK
• Pass the required Message text that we want to show to MESSAGE_TEXT
• Now save and activate
• If you test the message will be displayed at the bottom of the screen
• If you want to display the message at a particular place then insert MESSAGE AREA screen element in the layout of the View
• Then the message will get displayed in the inserted MESSAGE AREA
• There are different types of messages in webdynpro

please have a look at the following link for detailed explanation MESSAGE GENERATION IN WEBDYNPRO ABAP

Points please if helpful

Hi Shelwin,

In Webdynpro You can use only Message Manager (IF_WD_MESSAGE_MANAGER ), which is already inbuilt and you can acces it through code wizard.
