Download excel file in WDA and password protect

Hello,

I have read through many blogs but cannot find an answer to my question, so here goes... I want to be able to download an internal table/context node to a Excel spreadsheet that is password protected from WDA. I can see that function module EXCEL_OLE_STANDARD_DAT can be used to add a password, but can someone advise the best way to perform the download in Webdynpro ABAP?

Cheers, Russ.
