Thank you for your reply Tomek,
i have already set 'Display Null Value --> Yes' and still it doesn't allow me to leave it null after a value has been given.
Is your item set as required? What's the error message?
Good day sir,
let me explain a bit further.
It is not that the system does not allow me to proceed when i am pressing a button as if i have a validation or something.
My issue is that, while i am filling the information on this page i cannot insert the null value so i can apply it with the button.
It does not have the 'x' icon on popup lov to erase the given value.
