DOUBLE_CLICK and LOOP

Question

Hi all!
I have 2 internal tables g_t_mbew and g_t_sloc.
g_t_mbew is appended trough loop into output table itab_custdata of ALV list.
after display of the first ALV i would like to trigger DOUBLE CLICK event on that ALV. DOUBLE_CLICK should trigger an output of another screen.
My question is as follows: how can i loop at internal table g_t_sloc and search only records that correspond to the DOUBLE_CLICKED row, my search criteria should be MATNR field.
with:
READ TABLE g_t_sloc INTO wa_sl INDEX e_row-index.
i only get one record, how can i retrieve all the record that have same MATNR in g_t_mbew and g_t_sloc????
thanx!

Hi
  Below is the reply to each of your questions:
1. How to trigger Double-click?
A. In the PBO of screen, set PF-STATUS. In the PF-STATUS, activate the   Function code 'PICK' (F2). Thats all. Now when u double click, the ok_code field will contain the value 'PICK'.
2. How to identify the double clicked record? In the PAI of the screen, write this code. 
     DATA t_rowids TYPE lvc_t_roid OCCURS 0.
*&      Module  USER_COMMAND_0100  INPUT
PAI for Screen 100
MODULE USER_COMMAND_0100 INPUT.
   REFRESH t_rowids.
  CALL METHOD obj_alv_grid->get_selected_rows
    IMPORTING
      et_row_no = t_rowids.
     <b>Here t_rowids will contain the row number which is double clicked.</b>
      READ TABLE t_rowids INDEX 1.
      READ TABLE itab INDEX t_rowids-row_id.
     <b> Now itab work area contains the Double clicked record. ITAB is the Internal table displayed in the first screen.</b>
3. how can i loop at internal table g_t_sloc and search only records that correspond to the DOUBLE_CLICKED row, my search criteria should be MATNR field?
  LOOP AT g_t_sloc INTO wa_sl WHERE matnr EQ itab-matnr.
  Do your processing here. 
  ENDLOOP.
Same way for g_t_mbew.
