Download ALV Output to Excel

Hi,

I have an issue that in ALV output we have 1 Lakh Records & Columns are dynamically increases.So while I am downloading through standard dump is coming bez of time out .

I already used SCMS_TEXT_TO_BINARY but only first column is displaying in excel.

I already tried it by convert it to String & then to Binary.Because of dynamic internal table it is also taking lot of time.

I searched Forum but I didn't any related document.

Help me to solve this...

Regards

Shek
