hi all
I have got the below piece of code from various other posts in SDN for the automatic refresh of ALV list.
But this code does not work in ECC. Can anyone help me what is the issue with this.

Hi Nitin,
In your USER_COMMAND form, I agree with the MOVE 'X' TO is_selfield-refresh
But I disagree with the SET USER-COMMAND '&OPT'.
What issue are you facing: syntax error ? no refresh ? short dump ?
KR,
Laurent
