Infoset Creation for Segmentation

Hi,

I am new to segmentation and i have basic idea about it. My requirement is to create a new infoset for BP Role-wise segmentation. I have identified that I can createZinfoset by joining BUT000 & BUT100. But I am not sure about the steps involved.

I need you help for Zinfoset Creation in SAP CRM.

Regards,

Sunil
