First period setup with eliminations when migrating from another FCC app

Summary:

We are migrating from an old FCC environment to new FCC environment with chart of account changes.

To do so, we have created an FCC application, imported metadata (converted CoA), Created integration to load base entity data. Only change would be the old FCC has historical data from FY16 onwards but we are starting with FY20 & agreed to load FY20 YTD figures in the system to start with. We still need to track data by source (Managed Data, Journal Input, Other Data & Intercompany Eliminations)

The data looks good at base entities, but the top level entities have variances due to Intercompany eliminations - both system eliminated values & elimination data by configurable consolidation rules.
