update dynpro field

Hi,

I am currently adding some dates validations on an user exit. When I validate a date, I call a pop-up window to tell the user the date is wrong and I also suggest a new one. My problem is that I can´t update the field in the dynpro with the new value for the date afther the user accepted to change the date with the one I suggested.

Is there anyone who can help me with this?

Thanks in advance,

Best Regards,

Ezequiel Martin
