ITSM Reporting in Web UI Transaction

Hello experts,

I read documents on how to perform BI reporting in Solution Manger system.

I understood there are three BW strategies, like BW can be same client as solman, different client on solman system and separate BW system.

As I understood, in order to perform BI reporting some Standard BI content(DSO & BEx) needs to be activated in BW system. Data to these DSOs will be loaded by job which can be set in extractor framework of solman system.

I checked ITSM BW Reporting Cockpit, this is cockpit in solman system for accessing BW reports. Here I have below question.

1. What queries ITSM BW reporting cockpit uses? Is the cockpit uses standard BI content queries?
2. If I make customization in standard BI content query or create new BEx query, will it available in cockpit or what setting needed to add custom report to cockpit?
3. If BI content is activated into separate system, can ITSM cockpit be customized for accessing queries of different system?
   

Any help will be appreciated.

Thanks,

Swati
