You can determine the selected rows by calling the method get_selected_rows. Once you know what rows have been selected you can delete them from you internal table.

CALL METHOD o_grid->get_selected_rows

IMPORTING

et_index_rows = lt_rows

et_row_no = lt_rowno.

Hi

CALL METHOD grid->get_selected_rows

IMPORTING

et_index_rows = t_selected_rows.

To get the selected rows

perform operation on your final internal table (remove the records from your table)

(put this under when sy-ucomm = pushbutton code)

and again call

CALL METHOD grid->set_table_for_first_display

EXPORTING

is_layout = wa_layout

CHANGING

it_outtab = t_outtab[]

it_fieldcatalog = t_fldcat

EXCEPTIONS

invalid_parameter_combination = 1

program_error = 2

too_many_lines = 3

OTHERS = 4.

pass the same internal table again to the display

now out put will be refreshed and will not show the deleted records

When I pass the value obtained from the get_selected_rows method , I get a type mismatch error. I am not able to get the value and use it as an index to access my internal table , here is what my code looks like. :

FORM CANCEL_SEL.

DATA : TABIN TYPE I.

DATA T_SELECTED_ROWS TYPE LVC_T_ROW.

DATA LT_ROWNO TYPE LVC_T_ROID .

C_SELQUANT_N TYPE P DECIMALS 3.

CALL METHOD GO_grid->get_selected_rows

IMPORTING

et_index_rows = t_selected_rows

et_row_no = lt_rowno.

*APPEND T_SELECTED_ROWS.

*TABIN = LT_ROWNO.

CLEAR ITAB_W.

READ TABLE ITAB INTO ITAB_W INDEX <b>T_SELECTED_ROWS-ROW_ID.</b>C_SELQUANT = ITAB_W-SEL_QUANT.

C_BALQUANT = ITAB_W-BALQUANT.

C_SELECTED = ITAB_W-F_SELQUANT.

C_SELECTED = C_SELECTED - C_SELQUANT.

C_BALQUANT = C_BALQUANT + C_SELQUANT.

C_SELQUANT = 0.

ITAB_W-SEL_QUANT = C_SELQUANT .

ITAB_W-BALQUANT = C_BALQUANT.

ITAB_W-F_SELQUANT = C_SELECTED.

MODIFY ITAB FROM ITAB_W INDEX T_SELECTED_ROWS.

call method go_grid->refresh_table_display.

ENDFORM.

I have to find the index and pass it to the internal table to be able to update it .The bold portion is what is giving me trouble.

CALL METHOD o_grid->get_selected_rows

IMPORTING

et_index_rows = lt_rows

et_row_no = lt_rowno.

LOOP AT lt_rowno INTO lh_rowno.

READ TABLE t_screen INTO lh_screen INDEX lh_rowno-row_id.

ENDLOOP.
