FI-CA reporting and analysis

We are using SAP for Media, which I understand has significant similarities to SAP for Utilities.

Both our subscriptions billing and our SD billing runs through FI-CA.

Once these transactions hit FI-CO we loose site of the detail. All transactions are aggregated via the reconciliation keys and posted with a singular document type.

Are there any standard ECC or BI optimised for HANA reports available that will enable us to analyse the information that ends in the GL, with reference to the detail sitting in FI-CA?

Thanks
