Dynamic Date variant

Hi All,

I have a requirement to update "Planned Start Date"  dynamically in the variant created for Marketing->campaign.

I have added below logic in CPGAS_ADVSEARCH->ASCampaign(View)->DO_INIT_CONTEXT.

   data: lr_qs TYPE REF TO cl_crm_bol_dquery_service,
*        l_selection_parameter type ref to if_bol_bo_property_access,
         lr_col_params TYPE REF TO if_bol_bo_col,
         l_selection_parameter type ref to if_bol_bo_property_access,
          l_cnode type ref to cl_bsp_wd_context_node_asp,
          l_date type string,
          l_name type ref to NAME_KOMP.

FIELD-SYMBOLS : <gs_name> type any.
me->set_init_qs( abap_true )."Initialise the query

l_cnode = get_dquery_cnode( ).
lr_qs ?= l_cnode->collection_wrapper->get_first( ).
if lr_qs is not bound.
* add empty QS in order to allow application to prefill values
   assign l_cnode->('BASE_ENTITY_NAME') to <gs_name>.
    lr_qs = cl_crm_bol_dquery_service=>get_instance( <gs_name> ).
    l_cnode->collection_wrapper->add( lr_qs ).
endif.

lr_col_params = lr_qs->get_selection_params( ).

l_selection_parameter = lr_col_params->get_first( ).
while l_selection_parameter is bound.
  eh_onclear( ).
  l_name ?= l_selection_parameter->get_property( 'ATTR_NAME' ).
  if l_name->* = 'PLANSTARTDATE'.
    lr_col_params->remove( l_selection_parameter ).
    l_selection_parameter = lr_col_params->get_current( ).
    else.
      l_selection_parameter = lr_col_params->get_next( ).
      endif.

      endwhile.
l_date = sy-datum.
lr_qs->ADD_SELECTION_PARAM( iv_attr_name = 'PLANSTARTDATE'
iv_sign = 'I'
iv_option = 'EQ'
iv_low = l_date ).

Above logic is setting current date in Marketing->Campaign search screen .But when i create a variant with past date and try to execute it today even though do_init_context method is getting triggered date is not getting updated in the variant and i am able to see the result with past date only.

Kindly let me know how to update date dynamically in the variant
