Secondary List in REUSE_ALV_GRID_DISPLAY

Hi Experts,

I have made an REUSE_ALV_GRID_DISPLAY ALV Report in PP Module..it working fine ...

I want the functionality of secondary list i.e. when i double click on any line on the report it should show the detail list may be in a popup screen.

For reference The report has all the operations in it. If i select any line then i should be able to get the Split Quantities for that particular Operation.

For Ref. i am already having 6 buttons lined up...si i require the popup functionality for making report simpler. Currently if i double click on any line i get a popup which has the details of that particular line itself(i need to replace this).

FORM user_command USING ucomm LIKE sy-ucomm

selfield TYPE slis_selfield .

IF NOT ucomm IS INITIAL.

READ TABLE i_mat INDEX selfield-tabindex.

IF sy-subrc EQ 0.

SET PARAMETER ID 'ANR' FIELD i_mat-aufnr.

SET PARAMETER ID 'MAT' FIELD i_mat-matnr.

SET PARAMETER ID 'WRK' FIELD i_mat-werks.

SET PARAMETER ID 'RES' FIELD i_mat-rsnum.

SET PARAMETER ID 'RCK' FIELD i_mat-rueck.

SET PARAMETER ID 'RZL' FIELD i_mat-rmzhl.

SET PARAMETER ID 'AGR' FIELD i_mat-arbpl.

SET PARAMETER ID 'CAG' FIELD i_mat-plnnr.

ENDIF.

CASE ucomm.

WHEN 'CO02'.

CALL TRANSACTION 'CO02' AND SKIP FIRST SCREEN.

WHEN 'CM01'.

CALL TRANSACTION 'CM01' AND SKIP FIRST SCREEN.

WHEN 'CO13'.

CALL TRANSACTION 'CO13' AND SKIP FIRST SCREEN.
