In which tables are the data for the aplication KSB1?

I'm getting data from Qlik View with a BI tool called Qlik View.

I need help to find in which tables are the data for KSB1 aplication.

I've found something in COBK and COEP but there's more table involved since I didn't find all data.

Somente can help me please?

Regards.
