This document provides an overview of the mass additions process in Oracle Assets, which involves five main steps: 1) Create Mass Additions imports asset data into the FA_MASS_ADDITIONS table from external sources like legacy systems or Oracle modules, 2) Prepare Mass Additions adds additional data fields to the mass additions, 3) Post Mass Additions creates actual assets by posting the data, 4) Delete Mass Additions removes mass additions no longer needed, and 5) Purge Mass Additions completely removes deleted mass additions from the system. The document describes each step and available reports to help manage the mass additions process.
