OFSAA is abbreviation for “Oracle Financial Services Analytical Applications” and OFSAA is an applications which read data extracted from legacy sources and save results in the OFSAA results tables. Old OFSAA versions (named OFSA) had a series of Discoverer reports but these reports were not very userful so they were not generally used.
OFSAA has optional modules for reporting / analysis of the generated result data: ALM Analytics and Profitability Analytics, both built over OBIEE.
