AX 2012 - Bypass validation when clicked an action button up

Hi All,

I have an action button up and some textbox field at lower. I need to bypass validation when clicked action button up at that form. It wants me fill mandatory fields before click action button. In some situations that’s a bit silly I think. I could do this with other programming languages.

Is there any way for do this?

If it is mandatory it means that it has to be filled in. Right?

If a field is mandatory only in specific conditions, identify the situations and do a validation.
