Internal table modification in ABAP object event

Former Member — Sun, 09 Sep 2007 05:26:51 GMT

Hi Gurus

I have an internal table displayed using ALV - OOPS concept. THe internal table has 15 rows in my test program but it can go up depending on user inpout.

I am able to display it . on the screen . One of the fields is editable . It is required that it take input from user and on pressing enter , the value entered in that cell should be subtracted from a total amout displayed in the cell next to it.

I have used the following code . There are no errors , but nothing happens when I edit it. The screen remains as it is.

Any help will be very useful

DATA : ITAB type ITABT occurs 0.

DATA : itab_w like line of itab.

CLASS LCL_EVENTS_D0100 IMPLEMENTATION.

METHOD handle_data_changed.

DATA: ls_good TYPE lvc_s_modi.

DATA : L_PLANETYPE TYPE ITABT-SEL_QUANT.

LOOP AT er_data_changed->mt_good_cells INTO ls_good.

CASE ls_good-fieldname.

check if column PLANETYPE of this row was changed

WHEN 'SEL_QUANT'.

CALL METHOD pr_data_changed->get_cell_value

EXPORTING

i_row_id = ls_good-row_id

i_fieldname = ls_good-fieldname

IMPORTING

e_value = l_planetype.

ENDCASE.

LOOP AT ITAB INTO ITAB_W .

read table itab into itab_w WITH KEY FINDEX = LS_GOOD-ROW_ID .

itab_w-f_balquant = itab_w-f_balquant - l_planetype.

modify itab FROM itab_w .

endloop.

ENDLOOP.

ENDMETHOD.

ENDCLASS.

Hi,

check this program

BCALV_TEST_GRID_EVENTS

u've to register the edit event with the Enter attribute, something like this

call method gr_grid_d0100->register_edit_event

exporting

i_event_id = cl_gui_alv_grid=>mc_evt_enter.

Well the problem is not solved, The code int he PAI , well it has its problems , like what is the type for v_valid. If I give it the data type of my internal table field , I get a type mismatch error.

Error mesage appears " sel_quant" not in s ABAP dictionary.

Sel_quant is the editable field in my internal table.

data : begin of itab occurs 0.
data : werks like t001w-werks.

yeah..thats how it had been declared.

It gives the error , when I change the data and click the green check at the top . So it can tell that change has taken place.

The error still shows ,

I appreciate your support.

Its actually very simple , I just want to get the input from user , and make changes to fields on the same row of the displayed ALV on which the user entered a value.

THanks for your help
