PREPARE TOOL BAR BUTTONS Method - Not able to see on the screen

Hello Experts,

  Not able to see the tool bar buttons on standard screen, On ERP_IT component.

Have extended the Standard tool bar buttons with the customs ones by implementing the PREPARE_TOOLBAR buttons.

I have coded some thing like this in PREPARE_TOOLBAR method of implementation class.

ls_button-text     = cl_wd_utilities=>get_otr_text_by_alias( 'CRM_UIU_BT_SALES_ORDER/SALESORDER_EDITLIST' ).
       ls_button-on_click = 'EDIT'.
       ls_button-enabled  = me->view_group_context->is_view_in_display_mode( me ).
       APPEND ls_button TO gt_button.

LS_BUTTON is of type :

  ls_button       TYPE        crmt_thtmlb_button.

Please help if any thing i am missing ?

Thanks and Regards,
