Dynamics attributes in a ALV component

Hi Guys,

I am triying to set dynamically two attributes that I have loaded dynamically. If I set them manually I can get the values, but when I want to set a value, my ALV doesn´t show this chage and the context contain these values but only for dynamic fields. When I use static attributes I can modify without problems.

How could I set these dynamic values like static ones?

Thanks,

Sergio.
