SAP BW BO configuration in information steward

Hi Experts,

We have built SAP BO reports(Webi) topup SAP BI bex query's.

We need to analyze data lineage ,impact analysis about report (Ex:If I change the definition of a specific SAP BW object ,What Universe or reports are affected . Or What SAP BW source does the universe source obtain It 's data )

Can any one suggest what are the configurations required in Information steward to get this details

Please suggest what source we need to configure ,what access level required to get the meta data for above requirements.
