HI Venkat ,

Use lo_el = lo_nd_nodename->get_element( NODE_ELEMENT = ur req attribute name).

then put the ref lo_el into the message.

Hi Venkat ,

You can use thecode below and modify it according to your field.

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 = 'hiiia '

element = lo_el_context

attribute_name = 'FIELD2'

receiving

message_id = msgid .

There is no relation to the lead selection with this , but still if you face any problem regarding lead selection ,

You can use SET_LEAS_SELECTIOn method of context at specified index .

hope this will solve your issue.

Venkat, you can use the REPORT_ATTRIBUTE_ERROR_MESSAGE for table column by passing the message object, context_element which has the error column and the attribute name.

see example in demo_messages,WDR_TEST_MSG_MANAGER_00 components.

i am displaying some message when no element is select on table

i do not understand how lead select get affected when no element is selected. when there is no element selected how come lead selection ?/

Hi Baskaran,

My code is like this...

if lv_pack_material is initial.

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 = 'Please Select Packing Material...'

ELEMENT = lo_el_pack_mat

ATTRIBUTE_NAME = 'PACK_MATERIAL' .

endif.

But it is giving error... Null Object reference at ...CALL METHOD lo_message_manager->REPORT_ATTRIBUTE_ERROR_MESSAGE

here.. Pack_material is one column in table .. used as drop down, when ever i not select any value i want to display error msg,

but it is giving error.

2. when i use REPORT_ERROR_MESSAGE...

if i select one row in table, suppose drop down value is not select it is giving error, but lead selection is removing in this table

and above this another table is there, that lead selection also removing.. why?

Thanks,

Venkat.

HI Venkat,

I guess the element that you are passing to the method REPORT_ATTRIBUTE_ERROR_MESSAGE is initial.

Put a breakpoint and check the value at runtime.

Somehow you will have to get the element to which you want to raise the error message and pass the refrence to the method.

Hi Aditya,

Except pack-material value all values in that table are field na, so why lo_el_pack_mat contains null values???

Check my omplete code..

• navigate from <CONTEXT> to <PACK_MAT> via lead selection

lo_nd_pack_mat = wd_context->get_child_node( name = wd_this->wdctx_pack_mat ).

CALL METHOD lo_nd_pack_mat->get_selected_elements

RECEIVING

set = lt_temp.

LOOP AT lt_temp INTO wa_temp.

CALL METHOD wa_temp->get_static_attributes

IMPORTING

static_attributes = ls_pack_mat. // This contains all values except pack-material

lv_pack_material = ls_pack_mat-pack_material.

if lv_pack_material is initial.

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 = 'Please Select Packing Material...'

ELEMENT = lo_el_pack_mat

ATTRIBUTE_NAME = 'PACK_MATERIAL' .

Thanks,

Venkat.

• navigate from <CONTEXT> to <PACK_MAT> via lead selection

lo_nd_pack_mat = wd_context->get_child_node( name = wd_this->wdctx_pack_mat ).

CALL METHOD lo_nd_pack_mat->get_selected_elements

if lv_pack_material is initial.

lo_api_controller ?= wd_This->Wd_Get_Api( ).

exit.

endif.

append ls_pack_mat to lt_pack_mat.

CLEAR ls_pack_mat.

ENDLOOP.

lo_nd_pack_mat->bind_table( new_items = LT_PACK_MAT

SET_INITIAL_ELEMENTS = abap_false ).

Pass the receiving paramater also..

Somthin like this..

DATA msg_id TYPE string.

CALL METHOD lo_message_manager->report_attribute_error_message
  EXPORTING
    message_text              = 'hi'
    element                        = lo_el_main
    attribute_name            = 'EMLID'
*    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                = msg_id
    .

Hi,

With drop down UI element in table and using attribute_error_message wont work.

2. when i use REPORT_ERROR_MESSAGE... 
if i select one row in table, suppose drop down value is not select it is giving error, but lead selection is removing in this table
and above this another table is there, that lead selection also removing.. why?

With out seeing your both table how they are connected , it is difficult to say why both tables are empty. Much more information is needed than what you have described so far.

Hi Basakaran,

Then which method i ahve to use to display error message on dropdown table column?

Thanks,

Venkat.

You can use this method(REPORT_ATTRIBUTE_ERROR_MESSAGE) but it will not not highlight the column with redline around it as u would expect when using attribute error messages.
