I've a screen (SE51) and i need to change field properties using an ABAP instrution.
I need to do this... if variable LV_NDEP_IN is not initial, user can't change field content.
I've tried this...
IF lv_ndep_in IS INITIAL.
SET CURSOR FIELD 'LV_NDEP_IN'.
ELSEIF lv_ndep_in IS NOT INITIAL.
screen-input = ' '.
but doesn't work.
Can somebody help me ?
