Error Handling
错误处理
| Error | Cause | Solution |
|---|---|---|
| Missing periods | Data gaps | Fill with zeros or interpolate |
| Percentage calc error | Zero budget | Use IF to handle div/0 |
| Misaligned categories | Changed chart of accounts | Create mapping table |
| 错误 | 原因 | 解决方法 |
|---|---|---|
| 缺失周期 | 数据存在缺口 | 用零填充或插值补全 |
| 百分比计算错误 | 预算为零 | 使用IF函数处理除零错误 |
| 分类不匹配 | 会计科目表变更 | 创建映射表 |
Examples
示例
Example: Monthly P&L Variance
Request: "Analyze why we missed budget by $500K this month"
Result: Variance waterfall showing revenue shortfall offset by OPEX savings
Example: Department Budget Review
Request: "Which departments are over budget YTD?"
Result: Ranked list by variance magnitude with drill-down to line items
示例：月度损益表差异
请求：“分析本月我们为何未达预算50万美元”
结果：差异瀑布图显示收入缺口被运营支出节省所抵消
示例：部门预算审查
请求：“哪些部门今年迄今超预算？”
结果：按差异大小排序的列表，可下钻至明细项目
