Download dynamic fields (based on changed layout) from ALV

Hello All,

Currently i am displaying 28 firelds in my ALV output.

I have created my own button for downloading the contents displayed using GUI_DOWNLOAD.

Say if user changes the layout and say now we have 35 fields in the layout.

Now when we click the DOWNLOAD button, i want to download these 35 fields instead of 28 fields.

Can anyone please help me on this...

Thanks in advance....

Regards,

Tarun
