Depends. You have at least two options (Ido may have others related to 3rd party software).
As you mentioned, BOE or BI is an option.
So is SAP Crystal Reports Server (CRS).
The above will depend on the loads you are expecting. Think of CRS as a light version of BOE. As far as sizing, etc.; you're best to talk to sales who can then recommend the best product for your needs. Sales ph: 866-681-3435
