BOL Object identification

HI Experts,

I have a problem related to BOL Objects identification

The problem is in Alert. I am trying to trigger an Alert at BP conform. For that I am using BuPaDetailB2B view .But I am facing problem to identify BOL Objects (attribute and root node). Could you please give me some brief idea about how I will identify correct attribute and root node for BOL.

Please share documents with me on Alert Modeler and BOL Object .

Thanks

Gaurav
