HI,

THIS METHOD CHECKS FOR ANY DATA CHANGED IN U R ALV GRID DISPLAY .

SUPPPOSE U HAVE CHANGED ANY RECORD IN ANY ROW OR COLUMN IT WILL TRACK ALL THOSE CHANGES AND RETURN <b>E_VALID</b>.

IF IT IS 'X' THAT MEANS DATA HAS BEEN CHANGED AT THEN USE THIS IN U R FURTHER CODE

DATA: v_edited TYPE CHAR1.

CALL METHOD alv->check_changed_data

IMPORTING

e_valid = v_edited.

CHEERS

IF ANY DOUBTS ALWAYS THERE

Hi,

Thanks for your immediate reply...I just wanted to know that the variable you declared 'v_edited' will get stored with 'x' if any change is made in the grid.

There is also a changing variable called refresh. what is its use ?

[Former Member]

I guess REFRESH will refresh the ALV with the changed values if u set that to X ,tr that..

DATA: l_valid TYPE c.

Data grid1 type ref to cl_gui_alv_grid.

CALL METHOD grid1->check_changed_data IMPORTING e_valid = l_valid.

This method checks if any data is changed on the grid if there any editable fields .

And updates the changed values
