Every month, loan data flows from the loan system into the data warehouse and then into a regulatory report. This month the loan system shows 48,210 loans with a $3.215 billion balance, but the warehouse only has 48,150 loans and $3.208 billion — 60 loans and $7 million short. The report is due in three days. How do you investigate?

每个月贷款系统的数据要送进数据仓库，再出监管报表。这个月贷款系统有 48,210 笔贷款、余额 32.15 亿美元，数仓里只有 48,150 笔、32.08 亿，差了 60 笔、700 万。报表三天后就要交，你怎么查？
