我面临的挑战是限制过去 90 天的数据运行，但要考虑到一组 ID 可能有不同的数据输入日期。如果我只是运行查询将数据限制为最近 90 天，它不会总是提取所有分组数据（每组 6 个数据）。大多数情况下，数据输入将在同一天完成。然而，有时我们没有这些值，因此数据会在第二天或几周后输入。我正在尝试解决以下问题：如果 5 项活动中的任何一项的输入日期在 90 天内，则可以获取可能早于 90 岁的同伴分组数据，以便它显示在报告中。
我有这个原始表（注意，我必须从活动代码中导出列）。
| 项目ID | 活动代码 | 活动说明 | 活动结果 | DTTM |
|---|---|---|---|---|
| 123456 | 15 | 客户ID | 999 | 24/4/24 18:01 |
| 123456 | 16 | 发票没有 | 11232 | 24/4/24 18:01 |
| 123456 | 1745 | 类别颜色 | 绿色 | 4/25/24 9:01 |
| 123456 | 2256 | 尺寸 | 大 | 4/25/24 9:21 |
| 123456 | 4748 | 数量 | 7 | 24/4/25 10:05 |
| 654321 | 15 | 客户ID | 1745 | 24/26/4 11:15 |
| 654321 | 16 | 发票没有 | 19121 | 24/26/4 11:15 |
| 654321 | 1745 | 类别颜色 | 蓝色 | 24/26/4 11:15 |
| 654321 | 2256 | 尺寸 | 中 | 24/26/4 11:15 |
| 654321 | 4748 | 数量 | 10 | 24/26/4 11:15 |
| 171718 | 15 | 客户ID | 149 | 24/20/4 13:25 |
| 171718 | 16 | 发票没有 | 12001 | 24/20/4 13:25 |
| 171718 | 1745 | 类别颜色 | 黄色 | 24/22/4 12:05 |
| 171718 | 2256 | 尺寸 | 小 | 24/22/4 12:05 |
| 171718 | 4748 | 数量 | 3 | 24/22/4 12:05 |
我想要得到的结果是这样的：
| 项目ID | 客户ID | 发票没有 | 类别颜色 | 尺寸 | 数量 | DTTM |
|---|---|---|---|---|---|---|
| 123456 | 999 | 11232 | 绿色 | 大 | 7 | 24/4/25 10:05 |
| 654321 | 1745 | 19121 | 蓝色 | 中 | 10 | 24/26/4 11:15 |
| 171718 | 149 | 12001 | 黄色 | 小 | 3 | 24/22/4 12:05 |
