1. data management issue(s): data source(s), data date, report date as well as data consolidation -- e.g. =+Sheet2!B2+Sheet3!B2 result on Sheet1!B2 on excel spreadsheet, but it was =+Sheet2!B2+Sheet3!B3
2. checkpoint and audit since "只是２周前才转给我的" it should be your priority
well, it was a challenge project for you...good luck.
