Send a table to bpm web service as parameter

Hello,

I need to send a table content to bpm web service as parameter in order to display table content on the approve window.

Does anybody have any sample or how-to guide to do this, i can send single parameters in a single type (1..1), if i make this (1..n) will it be enough to achieve this ? Is there anything else that i need to do to achieve this ?

Regards,

Yasin
