Hi deepika ,

In REPORT_ATTRIBUTE_ERROR_MESSAGE you have to pass the Msg text , context element , and attribute name of the UI element binded .

Look in to the sample code .

l_element type ref to if_wd_context_element.
l_element = wd_context->get_element( ).

 l_message_manager->report_attribute_error_message(
        message_text  = 'Error Text ''
        element = l_element 
        attribute_name = 'PERNR'   " Attribute Name of the UI binded 
*        PARAMS        =
*        MSG_USER_DATA =
           ).

Hi Deepika,

Here for the method REPORT_ATTRIBUTE_ERROR_MESSAGE, mandotory fields are

MESSAGE_TEXT

ELEMENT

ATTRIBUTE_NAME

Here ELEMENT v need to pass lv_el_context type ref of IF_WD_CONTEXT_ELEMENT.(Context Elemet Reference).

Suppose your context having an attribute 'KUNNR'.

So, here v need to pass in the below manner to raise an exception

    DATA lo_el_context TYPE REF TO if_wd_context_element.
    DATA ls_context TYPE wd_this->Element_context.
    DATA lv_gr2_visible TYPE wd_this->Element_context-kunnr.

*   get message manager
  data lo_api_controller     type ref to if_wd_controller.
  data 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_ATTRIBUTE_ERROR_MESSAGE
    EXPORTING
      MESSAGE_TEXT              = 'MESSAGE TEXT TO DISPLAY'
      ELEMENT                          = lo_el_context
      ATTRIBUTE_NAME           = 'KUNNR'
*      PARAMS                    =
*      MSG_USER_DATA             =
*      IS_PERMANENT              = ABAP_FALSE
*      SCOPE_PERMANENT_MSG       = CO_MSG_SCOPE_CTXT_ELEMENT
*      MSG_INDEX                 =
*      CANCEL_NAVIGATION         =
*      IS_VALIDATION_INDEPENDENT = ABAP_FALSE
*      ENABLE_MESSAGE_NAVIGATION =
*      VIEW                      =
*    RECEIVING
*      MESSAGE_ID                =      .

Kindly revert for further clarification.
