Display msg when Schedule line is changed

[former_member762910]

Hi Experts,

I have a requirement that when Schedule line qty is made zero then an error msg should be displayed.

Msg should be displayed as soon as qty is made 0 and enter is pressed and at the time of saving it.

I have tried to code in User exit field_modification, but still it does not work.

Plz suggest the way in which this can be achieved.
