Hi Darshna,

Hope i would be able to ans this ques as well.

some code snippet:

DATA:

l_current_controller TYPE REF TO if_wd_controller,

l_message_manager TYPE REF TO if_wd_message_manager.

Read your attribute to which your UI element is binded.

here i have attached an assistance class with the component, or else you can give a user defined message.

IF stru_flightinfo-connid IS INITIAL.

lv_text = wd_assist->if_wd_component_assistance~get_text( key = '002' ).

• report message

CALL METHOD l_message_manager->report_attribute_error_message

EXPORTING

message_text = lv_text

element = elem_flightinfo

attribute_name = 'CONNID'.

ENDIF.

in this case whenver your UI element is intial, the message would be displayed.

Hope this solves your Problem.

Cheers!
