Button at row repeater - How to identify what line button was clicked.

Hi,

I`m developing a WD application using ROW_REPEATER to show a list of items. For each item, I have a button to access another view to show the detail about the line where button was clicked.

My application is very similar with example showed in this link: http://help.sap.com/saphelp_nw70/helpdata/en/44/93d3bc2e8c60d6e10000000a114a6b/frameset.htm

How can I pass the ID of the line where button were clicked to detail view?

Many thanks!
