What can I do to keep a field from changing data by pressing an Actions button?

[Yesenia_Leon]

I have a record that, when changing state, a field places the data of the user who made the change of state. But when you press an action button, this field changes with the data of the user who pressed it.

What can I do so that this field does not change and keep the data of the user who made the change of state but not of the user who pressed the button of an action?
