Extract process chains data from SAP BW ?

Hello people !

I'm a new to SAP BI.

I would like to monitor the process chains with their Start data and time and their end date and time.

Here my questions :

1- How and where do I get these information ?

2 - Is it possible to extract it "Automatically" into a CSV file ?

3 - Is there any chance to "Vizualize this data directly with Microsoft Power BI ?

Regards,

Zakaria.
