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.
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.
check if column PLANETYPE of this row was changed
CALL METHOD pr_data_changed->get_cell_value
i_row_id = ls_good-row_id
i_fieldname = ls_good-fieldname
e_value = l_planetype.
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 .
