How to read row index when clicking on F4 search multiple rows

Question

Hi Experts,
I would like to read index of selected row in assignation block. Please help.
My requirement is to restrict product search base on product category available in same row of table row.
When I select f4 search on product ID, It shows me all products available in system, however user wants product search should be based on product catagory.
I have added following code in get_v_orderprod. Problem is when user click on f4 button on product for first time CONTROL doesnot go to get_v_orderprod method in BT111H_OPPT component btadmini contextnode firsttime pop up comes with open search of all product available in system.
DATA:  lr_admini            TYPE REF TO cl_crm_bol_entity,
         lr_iterator         TYPE REF TO if_bol_bo_col_iterator,
         lv_ordered_prod     TYPE REF TO crmt_ordered_prod_db,
         lr_collection       TYPE REF TO if_bol_bo_col,
         current             TYPE REF TO if_bol_bo_property_access,
         dref                TYPE REF TO data,
         lv_pr_catagory      TYPE string.
  FIELD-SYMBOLS: <l_data> TYPE data.
* if iterator is bound.
*      current = iterator->get_current( ).
*    else.
*      current = collection_wrapper->get_current( ).
*    endif.
  lr_iterator = me->collection_wrapper->get_iterator( ).
if lr_iterator is bound.
      current = lr_iterator->get_current( ).
    else.
      current = collection_wrapper->get_current( ).
endif.
lr_admini ?= current.
*   lr_admini ?= lr_iterator->get_by_index( iv_index = iv_index ).
  IF lr_admini IS BOUND.
    lr_collection = lr_admini->get_related_entities(
                 iv_relation_name = 'BTItemProductExt' ).
*   lr_collection = current->get_related_entities(
*                 iv_relation_name = 'BTItemProductExt' ).
    current = lr_collection->get_current( ).
*   if lr_collection is bound.
*      current  = lr_collection->get_current( ).
*    else.
*      current = me->collection_wrapper->get_current( ).
*    endif.
    IF current IS BOUND.
      TRY.
          dref = current->get_property( 'PROD_HIERARCHY' ).
          ASSIGN dref->* TO <l_data>.
          CHECK <l_data> IS ASSIGNED.
          lv_pr_catagory = <l_data>.
        CATCH cx_sy_ref_is_initial.
          RETURN.
      ENDTRY.
      CLEAR: lv_pr_catagory.
    ENDIF.
  ENDIF.
Is there anyway out to achieve this ?
Thanks

Hi Venkat,
<li>You are the right person to solve the problem .
<li>What you have to get it solved is place Break-point on REUSE_ALV_GRID_DISPLAY function module and break-point inside USER_COMMAND event where u press SCREEN button which takes you to table control and another break point where DELETE function you are doing. Definitely it works out.
Thanks
