Is possible change a text field value with ABAP?
Is possible change the value of a text field during PBO processing?
With "LOOP AT SCREEN" I´m able to change things like REQUIRED, VISIBLE, LENGTH, etc. But what I want is change the value of text field with ABAP (without edit in Screen Painter).
With an Input/Output field I change the value of associated variable and the field value automatically change. But didn´t work with text field. Is that possible?
I don't think that's possible because the field that you want to change acts like a constant.
