Deference between solutions in SAP BO EPM

Hello all,

Can anybody help me to understand difference between products that are included in SAP BO EPM (Strategy management, Business planning and consolidation, Financial consolidation, XBRL Publishing, Financial information management, Intercompany reconciliation, Profitability and cost management, Spend performance management)? I understand a main idea for Strategy management, Business planning and consolidation and XBRL Publishing, and what is the main purpose for other applications?

At this page http://www12.sap.com/solutions/sapbusinessobjects/large/enterprise-performance-management/index.epx I can find very common information. Where can I find more detailed description?

Regards,

Veronica.
