Add button to toolbar dynamically using WD_BADI_DOMODIFYVIEW

Hello all,

I am trying to add a button to standard FPM button dynamically.

In an implementation of WD_BADI_DOMODIFYVIEW I have written following code as below -

DATA : lo_toolbar                TYPE REF TO cl_wd_toolbar,

           lo_toolbar_button     TYPE REF TO cl_wd_toolbar_button,

           lo_tool_item             TYPE REF TO if_wd_toolbar_item.

IF ir_view_info->get_name( ) EQ 'CNR_VIEW'.

     lo_toolbar ?= ir_view->get_element( 'TOOLBAR' ).

     CALL METHOD cl_wd_toolbar_button=>new_toolbar_button
             EXPORTING
               enabled   = 'X'
               id        = 'CUST_BUTT'
               on_action = 'DOACT'
               text      = 'Custom Button'
               view      = ir_view
               visible   = '02'
             RECEIVING
               control   = lo_toolbar_button.

     lo_tool_item ?= lo_toolbar_button.

     CALL METHOD lo_toolbar->add_toolbar_item
             EXPORTING
              index            = 7
               the_toolbar_item = lo_tool_item.

ENDIF.

In this case, no error is occurring and in ir_view->toolbar attribute toolbar items, i can see the dynamically created button added to the list, but it is not getting displayed.

Can anyone tell what or where am I missing?

Regards,

Yayati
