Question

i want to hide the last entry of a line when i click on the checbox of my ALV

Answer 1

u want to hide or delete?
instead of using check box, u can use a button to display there.
it can be achived like below.
data: ls_lvclayout type lvc_s_layo.
LS_LVCLAYOUT-SEL_MODE = 'D'.
now in set_table for_first_diaplay
CALL METHOD GO_GRID->SET_TABLE_FOR_FIRST_DISPLAY
      EXPORTING
      <b>  IS_LAYOUT            = LS_LVCLAYOUT</b>
do like above.
then u click on the row, and the row will be selected.
now using the method GET_SELECTED_ROWS, u can get the data of the selected row and u can now manipulate what ever u needed.
data:
SEL_ROW TYPE LVC_S_ROID,
SEL_T_ROW TYPE LVC_T_ROID.
CALL METHOD GO_GRID->GET_SELECTED_ROWS
    IMPORTING
      ET_ROW_NO = SEL_T_ROW.
LOOP AT SEL_T_ROW INTO SEL_ROW.
          read table <itab> index SEL_ROW-ROW_ID.
          check sy-subrc = 0.
< now write the logic  like making the field blank and modify the itab>.       
        ENDLOOP.
