The client had 300+ companies, each with many financial dimensions, which resulted in building 180,000+ records in the migration tables. When reviewing the code that builds this information, class LedgerFrameworkSetupHelper, method setupDimensionMergeTable, the records were being read and inserted one at a time, and not using the bulk insert controls. this causes high load on SQL and is also very inefficient.
