I have an editable ALV Grid (based on CL_GUI_ALV_GRID object). I am able to add data and save it. However:
(1) When I edit 1 particular column of grid (change number or make it blank), I get a short dump with message "GETWA_NOT_ASSIGNED - Field symbol has not yet been assigned".
(2) When I edit one of the columns of the grid, the change seems to be also affecting the column next to it. (ex: If I change value of first column to 10, the second column also shows value of 10 after data has been saved)
Can anyone help with these issues please?
