Smartform to HTML conversion

Hi,

I need to convert Smartform data stream into HTML format and

pass the same to Webdynpro application where it will be displayed on the browser.

I have specified Smartform output format as 'XSF output+HTML'.

Use of BSP application is ruled out due to certain limitations.

The FM ‘CONVERT_OTF’ returns data in ASCII or PDF format only.

Can any one tell some Function Module name to convert

Smartform data to HTML format or any other way out?

thanks.
